Hello Telerik team,

I'm using this article from your tutorial to add Close buttons to RadTabControl. I added the buttons, but I cannot seem to manage to add UserControl as Content for the tab

<Setter Property="ContentTemplate">

<Setter.Value>

<DataTemplate>

<Grid>

<UserControl Content="{Binding Content}" />

</Grid>

</DataTemplate>

</Setter.Value>

</Setter>

The Content property is of type UserControl. Can you give mi a hint how to do that?
The example this way is loading my custom user control in the tab, but when I load multiple tabs (for example lets call them 1 and 2) and when I select 1 tab, then 2 tab and then 1 again an exception is thrown:

{System.ArgumentException: Value does not fall within the expected range.
