Hi,
in my wpf usercontrol, I have a RadGridView with a RowDetailsTemplate inside of it. The template contain a RadTabControl and a only one TabItem with nothning inside of or if you want, we can add a TextBlock inside of it, it doesn't matter.
When I see my grid, I have my column with the "+" sign, when I click on the sign, my app hang and after 1 or 2 minutes, my Visual Studio tell me that I fall in an infinite loop.
Juste the fact to remove the RadTabItem it solve the problem!!!
Here is the xaml of my control:
