Focus is not returned to control after IsBusy is turned off

[Geoff Hardy]

We have a RadGridView which is contained within a RadBusyIndicator. The RadBusyIndicator.IsBusy property is bound to the IsBusy property on our underlying ViewModel. In the RowEditEnded event of the RadGridView, we do a web service call to update some data and set IsBusy to true on our ViewModel, which activates the RadBusyIndicator, blocking the user from editing the grid while the web service call happens. When the web service call is complete, we set IsBusy to false on the ViewModel and the RadBusyIndicator stops showing itself.

The problem is that the focus is not returned to the RadGridView afterwards - it is not obvious what control actually has focus after the RadBusyIndicator animation is complete. Ideally it should return to the RadGridView since that had focus previously.

Is this by design or is this a bug? It seems like the obvious thing that you would want the RadBusyIndicator to do is to return focus to the previous control that had focus.

Thanks in advance,

Geoff

So how can this be done in code?  I have a form that contains the RadBusyIndicator and a bunch of text boxes.  I am implementing an autosave feature that when the LostFocus of the textboxes is executed I set the IsBusy to true and save the data.  The problem is if the user uses the TAB button to go to the next box the RadBusyIndicator shows up and when it goes away the next textbox does not get focus.  I have tried to call Focus() on the next textbox after I SubmitChanges  and set IsBusy to false, but still can't get the control I want to get focus.

I hope this makes sense.  Basically I want the TAB to take the user to the next control after the BusyIndicator disappears.

Thanks,

Jason

Hello Jason,

Into your scenario I would suggest you save the focused element when some of the textboxes lose focus. Using a DispatcherTimer you can focus it back after the RadBusyIndicator has disappeared. I have created sample example to demonstrate you how to do this.

Hope this helps.
