I want to start to implement a new web application (with many user interactions) from the scratch. I have 2 years experiences with ASP.NET. Now Microsoft offers ASP.NET MVC. I have read a little about the concepts behind, but I am not sure if I should use the classic ASP.NET variant or the new one. Perhaps it makes sense to mix it ? Or s...
Hi, I was wondering if it's possible to use the FilterDescriptor control from code behind? On the page load of my form I set the datasource of a grid in the code behind, not using a DomainDataSource control, like: TestDomainContext context = new TestDomainContext(); dataGridEmployees.ItemsSource = context.EmployeePositions; context.Lo...

I'm trying to write a Silverlight application that reads a media file from a database (most likely a .mpeg or .mpg) and play it on the fly using either a Silverlight MediaPlayer or ExpressionMediaPlayer. When I try using Expression Media Player it plays .wmv and .mp4 files but NOT .mpeg or .mpg file extensions. Is this even possible? If ...
I am just getting into the Silverlight world, and wish I didn't learn WPF first so I wouldn't be so frustrated with the little things that are missing. In WPF I was using commands (RoutedUICommand) for my view/UI to handle "events" (by event I mean something the user did) and passing them to the viewmodel. Now in silverlight I find tha...

We have a Silverlight application using the RichTextBox as a rich text editor for the user to create emails. We actually have our own serializer but essentially we are saving and restoring the Xaml. As far as I can tell it is impossible to restore any text containing curly braces. You can demonstrate this fairly easily by creating a Ri...
