Hi there

I have a few usercontrols loaded into a tabcontrol via MVVM in WPF.

Within the XAML for the usercontrol I am setting focus to a textbox using the FocusManager, however this appears to only work when the first instance of the usercontrol is created.

Just to test I added a loaded event handler to the usercontrol - this is only called on the first instance.

I'm using data templates for the user controls as follows:

    <DataTemplate DataType="{x:Type local:UserTypeViewModel}">
        <local:UserTypeView />
    </DataTemplate>

The textbox is focused as follows:

    FocusManager.FocusedElement="{Binding ElementName=txtName}"

Additionally I'm using a global event handler (for the textbox GotFocus event) which selects all the text using a dispatcher.

If anyone has any tips on how to achieve focus with every usercontrol I'd be very grateful.

Thanks, Ben.
