Stefan,

Thanks for helping with what message I want to trap.  But, how do I prevent editing in a particular cell?  My customer wants to turn editing on or off at a particular cell, as some cells in a column may be editable or not based on what is in the row.

So, given a data grid, how do I manage to prevent editing at the cell level?

Thanks.

Thanks, Stefan for all of your help.

Hello Mike,

I have been looking into your code, and I can say that it is a very good approach for achieving the thing you want.

Stefan,

I did manage to get the result I was looking for by trapping the GotFocus message on the grid, and then filtering on the OriginalSource to prevent a stack overflow.  Here is my code.  Do you think it's ok to take this approach, or is there a better one you can think of?

		private void dgExpandedPFT_GotFocus( object sender, RoutedEventArgs e )
		{
			if( e.OriginalSource == this.dgExpandedPFT )
			{
				Record[] records = this.dgExpandedPFT.GetRecordsInView( false );
				this.dgExpandedPFT.ActiveRecord = records[ 0 ];
				this.dgExpandedPFT.ActiveRecord.DataPresenter.ExecuteCommand( DataPresenterCommands.CellFirstInRecord );
				this.dgExpandedPFT.ActiveRecord.DataPresenter.ExecuteCommand( DataPresenterCommands.StartEditMode );
			}
		}

Ah, Stefan - I am fast becomming a fan of yours.  Thanks so much, the link gave me what I needed.  This, coupled with how I am setting cell editing permissions work together very well and now if a user clicks on cell that is not editable, it goes to the first cell in the row that is editable and I can only tab into cells that are editable.  This works really nicely.

I have one last question.  My grid is set to tab order 3 and when I tab from the control before it, to the grid, I can see that the entire grid has the focus.  What I want is for the tab to go not to the entire grid, but into the first editable cell.  How do I do that?

Thanks.
