I succesfully created some constants in Silverlight's XAML like that <sys:Boolean x:Key="foo">True</sys:Boolean> However, when I try to do the same with a DateTime (to initialize some DatePicker controls) <sys:DateTime x:Name="myDate"/> the system throws an XamlParseException "Unknown element: DateTime. [Line: xxx Position: xxx]...
I'm using PRISM (and thus the MVVM pattern). I've got a complex DateTime picker view with radio buttons. The user can pick today, yesterday, a date, a week of a year, etc. I use radio buttons for the different choices. What's the best way to do that in MVVM? I really can't think of a clean way. I could create lots of custom behaviors ...

Sorry for asking an complete n00b question, but I've tried everything I can think of and nothing has worked. Google hasn't been too useful, all the results are from ancient versions of Silverlight :( The problem: I've got an Silverlight User Control. The layout root is an Grid. The grid is defined so: <Grid.ColumnDefinitions> <C...

I've got a Silverlight control with a Data Form inside to create an entity in my db. Beside the client-side validation that comes for free with Silverlight 3 and the Data Form control, I also have server side validation rules.

A common technical decision nowadays is whether to build a ClickOnce rich client application or a web application. Here I'm focussing primarily on choosing between a WPF application or a Silverlight application. The chief benefit of Silverlight is obvious - it can be hosted in a browser. But, if a programmer used to WPF was to star...
Hey guys, I'm having problems with the ItemContainerGenerator in Silverlight 3. In my derived Custom ListBox I'm adding this handler: ItemContainerGenerator.ItemsChanged += new ItemsChangedEventHandler(ItemContainerGenerator_ItemsChanged); Every time the Items change I'm getting a call back. Fine so far. Now in the ItemContainerGene...

I'm using RIA Services in one of my silverlight applications. I can return about 500 entites (or about 500 kb JSON) from my service successfully, but anything much over that fails on the client side - the browser crashes (both IE and Firefox). I can hit the following link and get the JSON successfully: http://localhost:52878/ClientBin...
Where is the best place to put Style StaticResources? I have been putting the global and default styles in app.xaml and the page specific styles in page_name.xaml. Should every control have its own style StaticResource? Is it acceptable to put some style attributes right in the control? I have a page with 5 TextBoxes on it, should there ...
