RadTabControl with RadGridview as TabItem and complex collections

[Masha]

Hello,

I'm trying to implement the following:

<telerik:RadTabControl
           x:Name="Stage"
           ItemsSource="{Binding DistributionList}"
           DisplayMemberPath="Name"
           TabStripPlacement="Left"
           TabOrientation="Horizontal">

           <telerik:RadTabItem>
               <telerik:RadGridView
                   Name="Recipients"
                   ItemsSource="{Binding Recipients}">

                         .........

                       </telerik:RadGridView>
           </telerik:RadTabItem>

       </telerik:RadTabControl>

I have a collection of "DistributionLists" in the view model. Each item in this collection has a child collection "Recipients". I would like to show the Recipients in a GridView inside the TabItem of the TabControl but this doesn't seem to work. I'm not even getting the grid on the tab.

Thanks in advance.

Hi Masha,

In the code you pasted I see that you're populating the TabControl both through its ItemsSource and Items collection (adding a TabItem declaratively). This approach is not valid. You have to use either ItemsSource or Items but not both. I've modified you're code to demonstrated what I have in mind. Please take a look at the attached project and let me know if you have further questions.

All the best,
