    Hi,

    I'm building an Silverlight application using PRISM/MVVM and VB.NET. Currently I'm struggling with creating a Tree control of two Lists that I have in my ViewModel. The lists are quite simple, and I build the relation between them in my ViewModel. The Parents is default OptionType and the Childrens are of OptionType Checklist, looking like this:

    Parent 1
        [X] Child 1
        [  ] Child 2

    Parent 2
      [  ] Child 1
      [X] Child 2

    My problem is to communicate from the view to the viewmodel the Uncheck/Check behaviour of the RadTreeViewItems!
    What is the most correct and easy way to do this in PRISM/MVVM? I've tried using commands, but command binding is not supported in RadTreeView yet?

    Hello Frank -,

    Instead of using commands and events, you can bind the RadTreeViewItems CheckState property to a business property from your ViewModels. You can find more info here.

    Give this a try and let me know if this is what you had in mind.

    Best wishes,

    Hi Buzz,

    Thank you for reporting this issue. Please keep in mind that the corresponding link was supposed to lead to an article describing how the feature should be used in data binding scenarios.

    However, this feature is designed to be used in XAML defined scenarios, only. This is why we updated the article.Please take a look at this article and let us know if you need any further assistance.
