wpf - Binding with UpdateSourceTrigger==LostFocus do not fire for Menu or Toolbar interaction

Question

I noticed that bindings with UpdateSourceTrigger==LostFocus do not get updated when the user activates the menu or the toolbar.

This leads to the unfortunate situation that the last change that the user made gets lost when the user selects "Save File" from the menu or toolbar.

Is there an easy way around this or do I have to change all my bindings to UpdateSourceTrigger=PropertyChanged.

Answer 1

I know this is a bit old, but for any future reader, simply setting the following on my ToolBar worked for me:

FocusManager.IsFocusScope="False"
