IsEnabled not updating?

[Kristoffer]

I have a toolbar with a button that executes a command. When the command is executed, I set a property from code behind:
SetValue(IsRunningProperty, true);

A worker thread does some work, and when completed the property is updated again:
SetValue(IsRunningProperty, false);

The toolbar binds to this property as follows:
<telerik:RadButton Margin="2" Command="{StaticResource Commands.Run}" IsEnabled="{Binding IsRunning, Converter={StaticResource InverseBooleanConverter}}">
  <Image Stretch="None" Source="..." />
</telerik:RadButton>

This works as long as the toolbar is not focused. If I press the button and wait for my worker to complete, the button will remain disabled until I click in my RadDiagram.

Why isn't the toolbar updating immediately?

UPDATE: Ok, it seems this is caused by a call to someOtherWindow.Focus(). Still, why doesn't the toolbar update itself?

Hello Kristoffer,

RadToolBar is designed to be a separate focus scope. You can try setting the attached property:

FocusManager.IsFocusScope=False

in XAML and check if all your scenarios work as expected.

All the best,
