I have a MainWindow with 3 main buttons at the top and below a MainUserControl.

In the MainUserControl I have at top 3 UserControls with ButtonBars
and at the bottom a DataGrid.

When I enter data in a DataGridCell and I click into another cell a property change is fired in my ViewModel bound to the DataGrid.

When I enter data… and I click on one of the 3 main buttons again a property change is fired because of Lost Focus event.

When I … and I click on one of the buttons in the ButtonBar in the UserControl no property change is fired because there seem to be no Lost Focus event.

How can I fix that?

    FocusManager.IsFocusScope=”False” on the UserControl or other elements like Menu solved the problem and my property changes are raised now in the model 🙂
