Adding UserControl to RadTabControl and making added control fill available space

[Peter]

I am adding UserControls to a RadTabControl at runtime thus:

            var tabItem = new RadTabItem();
            tabItem.Header = somestring
            tabItem.Content = new RtiDetailViewer();
            ImagesTabControl.Items.Add(tabItem);

Where RtiDetailViewer is a UserControl.

However, I have been unable to find a way to ensure that the added UserControl fills the available space, any help would be appreciated.

Hello Peter,

First, we highly recommend you to build your UI in XAML and not in code behind, this way you can save hundreds of lines of code.
What is the Template of your custom control ? Is it possible to set HorizontalAlignment and VerticalAlignment to Stretch on your control or on the containers from its Template ?

Thanks for that, the user control is built in XAML but is loaded into the RadTabControl at run time based on user record/data selection.
But this works!!
