I've had the same problem for 2 years or more.  Exactly the same as in this thread http://xceed.com/CS/forums/thread/14706.aspx, InsertionRow in the FixedHeaders and one level of grouping.  Very intermittant and not reproducable. Happens when calling EndEdit() while focus is still in the InsertionRow, i.e. user enters something ...

Sounds like the future but disappointed that there will still be no support for variable height rows.  Is it anywhere on the roadmap? Michael

I've just been reading the press release and features for the forthcoming Silverlight grid.  Looks very exciting. From the features page:- 'Smooth-scrolling animations. Reduces the perception of lag thanks to the time required to execute the smooth scrolling effect. Fades in empty rows and data once they arrive. Also improves readability by ...

Try this:-     //  reload the view   DataGridCollectionView dgcv = dataGrid.ItemsSource as DataGridCollectionView;   if (dgcv != null)    dgcv.Refresh();   --Michael

The behaviour of EditTriggers when tabbing between cells in 3.5 has changed/broken compared to 3.2.  You can see this in WPF Live Explorer => Editing Data => Edit Modes.  When the trigger is 'Cell is current', tabbing alternates between the focus rectangle and actually placing the cell in edit mode. Is there any way to fix ...

Hi Odi, Yes, one could think of this as two separate requirements.  I was really suggesting the second (pre-generating the next page and rendering a row at a time) as a necessary step to solve the first (smooth scrolling) whilst maintaining responsiveness.  I hadn't realised that that was effectively what the DataGrid was ...

Hi Odi, I've just read your Post no. 22142  in reply to BringItemIntoView and scrolling re disadvantages of ATV and the requirement that all rows have the same height.  That's a major diappointment for me.  Most of my grids have fewer than 20 rows but each row has at least one column containing a variable amount of text or ...

Hi Odi, Is V3.2 still on course for release in May?  Are you able to be any more specific yet? Thanks, Michael

Any more news on this?  I started getting the same message when I upgraded to version 3.0.8576.14450 In my case I had handlers for Cell.EditEnding/EditEnded like so:-         <Style TargetType=''{x:Type xcdg:DataGridControl}''>            ...

Hi Odi,   The PDC smooth scrolling demo looks very interesting.   However all your demos assume thousands of 'single line' rows.  My app needs to display a small number of 'tall' rows; i.e row height maybe 2-3 inches and so there may be only 2 or 3 rows on a page and maybe 5 pages.  There is quite a lot of binding for ...
