Hi everyone, I have an ItemsControl in my View, that is bound to an ObservableCollection from ViewModel. The collection is filled, and afterwards an event from VM to view is raised (think search results and SearchFinished event).

I'm afraid my Google-Foo is failing me again today. I'm trying to find a good tutorial on creating custom ItemsControls in Silverlight (though I imgaine a WPF version might work as well). I'm trying to create a custom ItemsControl that will be something of a virtualized ListBox. What I'm trying to accomplish isn't really similar enoug...
I have a TreeView which uses a custom ItemsPanel to show the first level of items in a StackPanel, but I need to show subitems in a StackPanel too. The problem is, the second level of items are shown in a WrapPanel, and as HierarchicalDataTemplate doesn't have an itemsPanel property I'm not sure how to do this. This is my xaml: <TreeVie...

I am using Microsoft UI Automation (i.e. AutomationElement) to run automated acceptance tests against my application. This has gone well, but I've hit a situation that doesn't appear to be exposed to the automation framework. I have an ItemsControl (although I could be using one of its derived controls, e.g. ListBox) and I am using Coll...
