(this question is a refinement of my other question on this topic which was a bit complicated but I really want to understand why this doesn't work so here's a more straight-forward example) WHAT I WANT TO DO: create a simple class (no XAML) in one project which inherits a WPF UserControl (with XAML) in another project. Here is my inhe...

There is a plenty coding guidelines/standards available for c# language. However I couldn't find anything "official" regarding XAML. I'm particularly interested in naming conventions of the visual elements, but something about formatting would be also useful. At the moment my XAML files look like a big soup of tags, not really human read...
I'm using XAML for serializing some objects and it's working great for the most part. The problem I'm now facing is when I change the data structure all the old objects produce an exception like the one below. I don't mind if the values are lost. Is there a way to turn off these exceptions and just have the xaml reader ignore unknown ...
In Expression Blend, you can view and edit the control template of objects in the "Objects and Timeline" panel. I'm wondering if there's an equivalent feature in Visual Studio or if there's something free (or very inexpensive) I can download that will allow me to do this. Here's a screen cap from Expression Blend that shows what I'm tal...
I was using the XamlPad from the .NET SDK, so I did a quick search for something similar but with more features and utility. My search turned up multiple alternatives, so I was wondering if anyone had any specific recommendations on which XamlPad alternative to choose. ...

Hi everyone! I was wondering if anyone knows how to use the TreeListView in WPF/XAML/Expression Blend. Without using the code behind. This what I want to do. I would like to populate a TreeListView with information, if the information's client and matter are the same, then just make that item a child of it. Example: Client 1= Kevin, ...
Either I'm not as intelligent as I once believed or the UI in Blend is really this bad. Is there any way to 'refresh' changes I've made to an XAML file in the designer? Something simple like changing 'Fill="Red"' to 'Fill="Blue"' does not show up in the designer unless I close and re-open the file. Google and SO were sadly and surpri...
