Question

The following code uses a ToolBar and correctly causes DataGrid.LostFocus (there by committing any uncomitted row-edits before the command is executed);

<Toolbar FocusManager.IsFocusScope="False">
  <Button Command="{Binding CommandName}" />
</ToolBar>
<DataGrid ... />

However, I am now trying to do the same using the Ribbon (oct10 release), but the following does not cause DataGrid.LostFocus to be raised;

<Ribbon>
  <RibbonTab>
    <RibbonGroup FocusManager.IsFocusScope="False">
      <RibbonButton Command="{Binding CommandName}" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<DataGrid ... />

How can I raise this event using the Ribbon? I have tried moving the IsFocusScope through the other levels (Ribbon, RibbonTab, RibbonButton) to no avail.

Don’t like this due to the need for code behind, but in the absence of any other answers;

<Ribbon>
  <RibbonTab>
    <RibbonGroup>
      <RibbonButton Command="{Binding CommandName}" Click="dropFocus" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<Control IsTabStop="False" Name="focusControl"/>
<DataGrid ... />

And the code behind;

private void dropFocus(object sender, RoutedEventArgs e)
{
  Keyboard.Focus(focusControl);
}
