Hi,

GotFocus event is a bubbing event, so if i handle GotFocus event for GridView,everything in the GridView got focus should make the GridView onfocus.But why when i click on the column header it not work? I handle it like this:
this.gridView.GotFocus += new RoutedEventHandler(GridView_GotFocus);
seems click the column header can't trigger this event.

Hi kyle,

I have just tried this with the latest binaries (Q3 2010) and the event fires when I click on the column header.
Can you try with this version please?

All the best,

Yes,I've tried with the last version.But it still not work.My code just as above. Do i have some mistake?

Seems same as mine. The first time you click the column's header,it's will output "Telerik.Windows.Controls.RadGridView",but i add a button (or something else),you click the button,it's output "Telerik.Windows.Controls.RadGridView" as well.And i set a breakpoint in the Debug.writeline line,then click the header,it can't trigger this.

Hi kyle,

Can you please tell us the ultimate goal so we can provide some alternatives?

Thanks

Hi,

OK.Seems I should describe more clearly about my problem.Sorry for that. Assuming we have a page with some controls,for example,we have two GridViews named grid1 and grid2,and we also have a TextBox.When we click one of the GridView,it got focus and the TextBox will display  the name of it,grid1 or grid2.But now when we click on the column's header,it's belongs the GridView,but nothing happen.Do you got me?

Hello kyle,

You are right. It seems when you click on the column header - the sorting mechanism fires and prevents the gridview focus. What you can do is to subscribe to the Sorting event and perform the same logic (as with GotFocus) there.

Hope this is feasible for you.
