I have the following XAML
<dx:DXTabControl ItemsSource="{Binding List}">
<dx:DXTabControl.ItemHeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Label}"/>
</DataTemplate>
</dx:DXTabControl.ItemHeaderTemplate>
</dx:DXTabControl>
The List property in the DXTabControl 's DataContext contains a list of UserControls.
Each usercontrol, has in its DataContext a property "Label".
I would expect to see the Label value in my 2 tabs header but it doesn't work.
Could you help ?

Hi Sylvain,
Thank you for providing the sample code.
On my side, bindings inside the DXTabControl's ItemHeaderTemplate works as expected. So, I am afraid I do not quite understand how to reproduce the problem. I am attaching a small sample I used for testing purposes. Can you please let us know how we should modify it in order to see the issue in action, so that we can continue working on it?
Thanks,
Vito
In your sample, if TabItemInfo inherits from UserControl then it doesn't work anymore !
Because, I'm using DXTabControl as a Prism region, I'm putting some UserControls in the collection binded to DXTabControl.ItemsSource.
Hi Sylvain,
Thank you for your response, and for providing the additional information.
I now see the problem. This seems to be a well-known issue with binding to the UserControl properties. I suggest that you refer to the following thread, where this issue is discussed, to find more information on this subject:
Problem with binding TabControl to collection of UserControls
The only solution we can suggest is to use a workaround, suggested in this thread: use the ItemContainerStyle to set up header bindings. I am attaching a modified project, illustrating this approach in action. Hopefully, you will find it helpful.
Thanks,
Vito
