Enable/Disable a "vsct" button - Is BeforeQueryStatus the right thing?

Hello there,

I've a ToolWindow with a ToolBar, implemented with vsct. I want to enable/disable a button in this ToolBar, when there is an item selected in the WPF datagrid.

Currently I'm using the BeforeQueryStatus-Methode to handle this. The problem is, that this method only get's called when there's a new ui state (or something similar). But that's not the case every time. So the enable/disable action is not quite constant or reliable.

How can I handle this. Can I force a UI refresh? Or is there another (better) approach.

Thanks,
Fabian
