sorskoot: PivotViewer – Custom Actions

sorskoot — 08/30/2010 23:01

PivotViewer series Building your first PivotViewer application Runtime PivotViewer collection creation PivotViewer - Working with Facets Handling PivotViewer events PivotViewer - Custom actions PivotViewer and MVVM . . .IntroIn this tutorial about the Silverlight PivotViewer control I would like to explain how to make use of Custom Actions. Small labels are placed on top of items in the viewer and clicking them will trigger an event. They look something like this:The only downside of these actions is that they aren’t fully implemented. So you’ll have to extend the PivotViewer control yourself. If you haven’t worked with the PivotViewer before, you might want to have a look at the Building your first PivotViewer application tutorial I wrote earlier first. This tutorial continues on that.Extending the controlStart by adding a new class to a Silverlight project and naming this PivotViewerEx. Make this class inherit from PivotViewer. Create an override of the GetCustomActionsForItem method. This method is called by the PivotViewer when it is in need of some custom actions. The id of the item the user is hovering is passed to this method. You can do some filtering of the actions based on that. In this example no filtering takes place and the whole collection of custom actions is returned.The list of custom actions is defined as property of this class. It is instantiated by the constructor.public class PivotViewerEx:PivotViewer { public List CustomActions { get; set; } public PivotViewerEx() { CustomActions=new List(); } protected override List GetCustomActionsForItem(string itemId) { return CustomActions; } }

sorskoot: Handling PivotViewer events

sorskoot — 08/27/2010 22:39

PivotViewer series Building your first PivotViewer application Runtime PivotViewer collection creation PivotViewer - Working with Facets Handling PivotViewer events PivotViewer - Custom actions PivotViewer and MVVM . . .IntroToday I would like to go into a little detail about the events used in the PivotViewer control for Silverlight. If you haven’t worked with the PivotViewer yet you might want to read the getting started tutorial I wrote earlier first.CollectionLoadingCompletedThe CollectionLoadingCompleted event is fired when loading of the collection is completed. CollectionLoadingFailedThe CollectionLoadingFailed event is raised when an error occurs when loading a collection. The event uses gets an instance of the CollectionErrorEventArgs class when it is fired. This class contains two properties.The first is ErrorCode. This property is of the enum type CollectionError and contains two values: DownloadError and ParsingError.ErrorCode equals DownloadError when there was an error downloading the collection. For example if the URL used in the LoadCollection method is wrong. The ErrorCode contains the ParsingError value when there is an issue with the .CXML file which prevents it from being parsed. For example a typing error in the .CXML.The second property used in the CollectionErrorEventArgs class is Exception. This property contains the exception thrown by he PivotViewer control. This exception can provide very useful information when building runtime collections. ItemDoubleClickedThis event is fired when an item in the PivotViewer is double clicked. The event is given a ItemEventArgs object. The ItemEventArgs class contains 1 property, ItemId. This string contains the ID of the items that is clicked. You can use this ID to get the whole item by calling the GetItem method on the PivotViewer control.private void Pivot_ItemDoubleClicked(object sender, ItemEventArgs e) { PivotItem item = Pivot.GetItem(e.ItemId); // insert something useful to do with the item here // like showing a popup with more info. } LinkClickedWhen the end-user click on

dennisdoomen: ALM Practices Part 11: Modeling the business domain using Domain Models

dennisdoomen — 08/25/2010 09:10

What is it? A domain model is a class diagram in which the classes and associations represent the business concepts and the relationships between them. Although you can use a piece of paper to draw up a domain model, in most cases a UML case tool is better suited for that. Business concepts such as orders, customers or contracts are represented by classes stereotyped as entity. Associations are used to illustrate the roles which that entity fulfills in in the relationship with other entities. An example of a domain model representing a recipe database looks like this: Why would you do it? Because a domain model centralizes the concepts and behavior of the business domain at one place Because while creating it, you'll run into many new important questions on both the static and dynamic aspects of the domain, including constraints, relationships, the business process, roles and responsibilities Because it can be used to verify that the developers and other team members have the same view on the domain as the business people have. What’s the minimum you need to do? You should clearly communicate that the domain model should not be confused with a data model. It does not imply anything about the database schema and should not contain specific decisions or changes because of that database. Make sure all entities, association roles, attributes, operations and other documentation comply with the Ubiquitous Language. Write in your native language, unless company policy says otherwise. Avoid bidirectional associations. It makes understanding the life cycle of related entities more difficult and introduces technical complexity that ripples throughout the entire system. I also found that bidirectional associations reduces the obviousness of the user interface, because a bidirectional relationships clouds the parent-child obviousness. Always use directional associations. Base those on the conceptional relationship between the entities, not on the way you intend to query the domain for presentation purposes. Always add roles to your associations. They may seem obvious, but by thinking about the role, you may find misinterpretations or an opportunity to get more insights in its purpose. Don't specify a multiplicity of 1, but always specify the others explicitly. Use a composite association when the child's lifecycle is dictated by the parent (like the Recipe-Ingredient association). Don't include any technical terms or .NET-specific types such as string or integer. Use text, number, money or another type from the Ubiquitous Language instead. Make sure that the individual class models are small and do not show more than what the model is intended for. If an entity has a status attribute, carefully consider what impact each status has on the editability and associations of that entity. If these constraint become very complex, consider modeling the State Pattern or choose a design in which

marcelmeijer: Windows Live 2011 Beta

marcelmeijer — 08/25/2010 08:00

Op de laptop van mijn zoon was om een of andere reden Messenger stuk. Na deinstalleren en installeren werkte het nog steeds niet. Om het probleem op te lossen hebben we uiteindelijk maar de Windows Live 2011 Beta geinstalleerd. Toen kon hij weer MSN-en. Maar Windows Live 2011 Beta zag er zo grappig uit, dat ik besloten heb deze versie ook op mijn laptop te installeren. En tot op heden bevalt het mij uitstekend. Vooral de integratie met al mijn social networks is erg goed. In een oogopslag krijg je een overzicht van alle updates. Uiteraard kun je ook naar de oude variant. Daar is niet veel aan veranderd, behalve dan dat er een groep FaceBook bijgekomen is. Wel is het veranderd als je meer chat sessies open hebt, voorheen had je meerdere schermpjes bij elkaar. Nu is het een scherm met meerdere tabbladen. Kortom het ziet er allemaal net weer een beetje beter uit. en beter geintegreerd met Windows 7. Ook Windows Live Writer is aangepast, daarover later meer!

sorskoot: PivotViewer – Working with Facets

sorskoot — 08/24/2010 22:31

PivotViewer series Building your first PivotViewer application Runtime PivotViewer collection creation PivotViewer - Working with Facets Handling PivotViewer events PivotViewer - Custom actions PivotViewer and MVVM . . .IntroIn this next tutorial about the Silverlight PivotViewer control I would like to give a little more depth on Facets. What are facets, and how are they used in runtime generation of collections using the PivotServerTools library.This tutorial continues on techniques from last tutorial about runtime collection creation. If you are just getting started using the PivotViewer control, you might want to have a look at the Getting Started Tutorial first. This tutorial is centered around the methods build in the last tutorial: MakeCollection and MakeItem. FacetsFacets are basically the properties on the PivotViewer that allow the visitor to sort and filter. Facets are also shown when viewing the details of an item.Facets are added to the collections by calling the Collection.AddItem() method. This method takes a couple of parameters. The first is the Name of the item being added. The second is a URL. This can be used to navigate to more details about the item for example. This URL is used when clicking on the Name of the item in the details panel. Then there’s the Description of the item. This text is shown on the details panel. The fourth parameter is the image shown in the DeepZoom part of the control. The ItemImage type from the PivotServerTools. Its constructor is used, to which a URL to the image is given. All parameters after that, from the fifth on are Facets. You can add as many as you need. A call to AddItem might look something like this: collection.AddItem( id, url, description, new ItemImage(new Uri(image)), new Facet("String value", FacetType.Text, id), new Facet("Integer Value", FacetType.Number, intValue), new Facet("Double Value", FacetType.Number, doubleValue), new Facet("Date value",FacetType.DateTime,date), n

sorskoot: Runtime PivotViewer collection creation

sorskoot — 08/17/2010 23:14

Intro Today I would like to show you how you can consume web services in the PivotViewer control for Silverlight and build a collection at runtime. This tutorial is based on examples found on www.getpivot.com and the getting started tutorial I posted earlier this week. This tutorial used the previous as a starting point, so if you haven’t read that you probably want to do that first. The only difference is that I named the project PivotViewerDynamic this time. The PivotViewer control loads a collection by reading an .CXML file. To get the PivotViewer to load a generated collection HTTP handlers are used to redirect the request for an .CXML file to custom code. This code, the Collection Factory, returns the collection in .CXML format. Requests for the DeepZoom images used in the collection are also redirected to custom code is capable of generating images on the fly or load them from the web. Building a Factory The factory class that will be building the collection is based on a class that can be found in one of the examples on www.getpivot.com. You can download this example here. Add the PivotServerTools project from this example to the project created in the Getting Started tutorial. And add a reference to the PivotServerTools project from the Web project. It is also include in the sample code for this tutorial. To be able to use the factory a custom HTTP handler needs to be build. This sounds more complex than it is. Start by adding a new class to the Web project and name this class CxmlHandler. Make this class implement the IHttpHandler interface. This will give you one method, ProcessRequest, and one property, IsReusable. Add one line of code to the ProcessRequest() method as shown below. The PivotHttpHandlers.ServceCxml() method will look for factories and returns the collection in .CXML format. Don’t forget to resolve a using to the PivotServerTools namespace. public class CxmlHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { PivotHttpHandlers.ServeCxml(context); } public bool IsReusable { get { return true; } } }To get the HTTP handler to work it has to be configured in Web.Config. To do this add the code below. <

sorskoot: Building your first PivotViewer application

sorskoot — 08/16/2010 21:10

IntroIf you haven’t had a change to look at the new PivotViewer control for Silverlight, have a look here or here. The PivotViewer enables visitor of you website to search large amounts of data very easily. The control takes a lot work out of your hands. Basically you tell it to load a collection and the PivotViewer takes care of everything else. Like adding controls to enter search and sort criteria. It uses DeepZoom to show large amounts of images and animate between states.Getting startedBefore you can start coding you have download the control itself. The Silverlight control can be downloaded from the PivotViewer section on Silverlight.net. You also need the Silverlight Toolkit which can be found here.Your first PivotViewerTo get your first PivotViewer control up and running create a new Silverlight project in Visual Studio and add references to all 5 PivotViewer assemblies to the Silverlight project. These assemblies can be found in C:\Program Files\Microsoft SDKs\Silverlight\v4.0\PivotViewer\Jun10\Bin or C:\Program Files (x86)\Microsoft SDKs\Silverlight\v4.0\PivotViewer\Jun10\Bin on 64bit system.In MainPage.xaml add an xml namespace definition for the System.Windows.Pivot namespace and add the control to the LayoutRoot grid. Getting data in the PivotViewer control has to be done in CodeBehind. The PivotViewer contains a method LoadCollection which takes an URL to a .CXML file. This file can be stored anywhere on the web and c

sorskoot: Adding options in Expression Blend extensions

sorskoot — 07/30/2010 23:21

IntroOften extensions for Expression Blend have to need to store some global variables. Why not use the mechanisms Blend itself offers? I’d like to show you how to add a custom options page to the options dialog.I’ve started the example project by creating a new C# WPF Custom Control Library project and naming it ExtendingBlendOptionsTutorial. The details on how to create a new Blend Extension can be found here. You need to make sure the Microsoft.Expression.Extensibility and Microsoft.Expression.Framework assemblies are referenced in your project. Both can be found in the Expression Blend installation folder on your machine.The architectural design is taken from the existing option pages that are used by Blend. Every existing page uses a '’…Page’ , a ‘…Control’ which is contains the xaml for the dialog and a ‘…Model’. The Model is bound to the Control. The example in this tutorial follows the same pattern. IPackage ImplementationLet’s start at the beginning. When Blend is started it loads the extensions using MEF. Therefore the extension has to be an implementation of the IPackage interface and has to be decorated with an Export attribute. The code is pretty simple. From the IServices provided by Blend an instance of the IOptionsDialogService is requested. This services contains a collection of all option pages. Every options page is an implementation of IOptionsPage. In this case a new TutorialOptionsPage is created in the Load method. A new TutorialOptionsModel is passed into this. After that the TutorialOptionsPage is added to the list of option pages. [Export(typeof(IPackage))]public class OptionsTutorialPackage:IPackage { public void Load(IServices services) { IOptionsDialogService optionsDialogService = services.GetService(); TutorialOptionsPage optionsPage = new TutorialOptionsPage(new TutorialOptionsModel(services)); optionsDialogService.OptionsPages.Add(optionsPage); } public void Unload() { } }

marcelmeijer: SQL Azure – Project Houston CTP

marcelmeijer — 07/27/2010 10:00

Al een tijdje is SQL Azure beschikbaar, zoals bekend de Database in de Cloud. Om objecten (tabellen, stored procedures etc) aan te maken moest je gebruik maken van de SQL Server 2008 R2 tools of Visual Studio 2010. Het was nog niet mogelijk om via de SQL Azure website andere zaken te regelen dan de firewall instellingen en het aanmaken van de database. De belofte was dat er een Online tool zou komen om objecten in de database te maken. Tijdens de PDC 2009 is daar een voorproefje van gegeven. Maar nu is de CTP van dit Tool beschikbaar gekomen. De codenaam is Houston. Op http://www.sqlazurelabs.com/ zijn alle developer preview zaken te vinden en op https://manage.sqlazurelabs.com/ is het beheertool te vinden. Deze zal uiteraard de komende tijd flink uitgebreid worden, want op dit moment is nog niet alles mogelijk. Het inlogscherm Na het inloggen is dit je startscherm. Door deze schermen kan gescrolled worden op het start scherm. Er is ook nog een scherm resources. De schermen voor het aanmaken van de verschillende objecten in SQL Azure.

marcelmeijer: Outlook Social Connector for Facebook

marcelmeijer — 07/14/2010 07:00

Sinds de release van Outlook 2010 zijn we bekend gemaakt met het fenomeen Social Connector. Deze was er voor SharePoint sites en Linkedin. Maar nu is er ook een connector voor Facebook bij gekomen. En tussen alle updates op LinkedIn, nu ook de updates vanuit Facebook. Bevriend worden met een van je contacten via Facebook is heel gemakkelijk. Als je kiest voor Facebook uit het eerste plaatje, dan wordt je vanzelf doorgerouteerd naar de Facebook site en wordt je aan je contact gekoppeld. De Social Connector for Facebook/LinkedIn/SharePoint is hier te downloaden; hij is er zowel in een 32 bits als een 64 bits variant.

Vandaag in de keynote van Microsoft Wordwide Partner Conference is bekend gemaakt dat samen met een aantal hardware leveranciers Azure Appliance beschikbaar komt. Daarmee ontstaat de mogelijkheid voor een om premises Cloud te hebben. Daarvoor heb je dan wel specifieke hardware nodig. Erg handig! Het is nog gelimiteerd, maar ik ben benieuwd naar de resultaten.

marcelmeijer: Windows Phone 7 Tools

marcelmeijer — 07/12/2010 23:14

De Beta van de Windows Phone 7 tools zijn te dowloaden. http://www.microsoft.com/downloads/details.aspx?FamilyID=c8496c2a-54d9-4b11-9491-a1bfaf32f2e3&displaylang=en Daarvoor is het nodig dat de vorige versie gedeinstalleerd is. De installer van de beta tools geef wel aan, welke je allemaal moet deinstalleren. Waar het bij mij mis ging, was het de-installeren van de Windows Phone Developer tools. Om de een of andere reden is de wizzard niet erg duidelijk en probeert de uninstall tools te installeren. Om deze toch te kunnen deinstalleren heb je de XNA Game Studio Cleanup Tool nodig (http://blogs.msdn.com/b/astebner/archive/2009/04/10/9544320.aspx). Daarna kunnen de Beta tools gewoon geinstalleerd worden! Happy WP7 developing!

sorskoot: Silverlight Databound Application Project Template

sorskoot — 07/09/2010 17:14

Intro One of the new additions in Expression Blend 4 is the Silverlight Databound Application Project template. I use that often when starting a new MVVM project. The template creates View and ViewModel folders and provides a good starting point for Model-View-ViewModel applications. The only downside is that this template is only available in Expression Blend and not in Visual Studio 2010. I’ve exported the project to a Visual Studio template to be able to use it in VS2010 too. Download The template can be downloaded here. Installation Just place the .zip in ??\Documents\Visual Studio 2010\Templates\ProjectTemplates\Visual C#\Silverlight Do not extract. It should work in VS2010 now.

sorskoot: Window Closing Event

sorskoot — 07/07/2010 19:37

IntroWhen running Silverlight 4 out of the browser it could become handy to know that the application is being closed. In case of my open source demo application SilverAmp (http://SilverAmp.CodePlex.com) I wanted to notify the user the application is being closed when music is still playing. Catching the eventIn Silverlight 4 a new event has been added to the System.Window class. This event is raised when the application is being closed. Closed in any way: by the user hitting F4; by the user clicking on the right-top cross; by a calling close on the application from within code or even when windows is shut down.The great thing about handling this event is that you can cancel it. In the example below the closing event is handled and the user is asked if he wants to exit the application. The application uses a MediaPlayer to play media which is named _internalPlayer. If the currentState of the player is playing than a message box is shown. If the user chooses not to quit, the closing is canceled by setting the Cancel property of the ClosingEventArgs to true. public MainPage() { InitializeComponent(); Application.Current.MainWindow.Closing += MainWindow_Closing; } void MainWindow_Closing(object sender, System.ComponentModel.ClosingEventArgs e) { if (_internalPlayer.CurrentState == MediaElementState.Playing) { if (MessageBox.Show("Music is playing, exit application?", "Exit", MessageBoxButton.OKCancel) == MessageBoxResult.Cancel) { e.Cancel = true; } } } One last note: you might want to add a check if the application is running out-of-browser. Using the closing event in browser causes an exception. Technorati Tags: Silverlight,OOB
