I figured it out.  The DisplayLayout.Bands.IndentationGroupByRow was set to -1.  When I set this to 0, it removed the blank header area.

With this solution, I lose the grey bars that go down the left side of the grid which add visual indicators of the seperate groups.  It would be nice to be able to keep the bars and have the header render for the entire width of the grid.

I applied the latest hotfix and it did not fix the issue.  It appears that the white area in the top left corner does not have any header element drawn on it.  This area takes on the background color property which is set for the grid.  If I set the background color of the grid to blue, the upperleft corner shows as blue.

 Do you have any idea why this little area would not have had a blank header drawn on it, or how I can get the grid to draw a blank header in this area so it matches the look of the rest of the header row?

 I am using version 6.2.20062.1083.

Thanks for your help.

All I did was use the InitializeLayout event to set the ViewStyleBand to OutlookGroupBy and set HeaderPlacement to FixedOnTop. Then I ran the app, grouped some columns, and expanded a few rows.  

Is it possible for you to share your code you used to create the grid so I can copy it on my machine and see if I get your result or my result?

Thanks.
