Grouping grid - memory exception

I am developing an mdi application. When I create a child form, i am initializing a grouping grid that is on the child during the form load. here is my code grdMemberships.DataSource = dt; grdGrpMemberships.TableDescriptor.GroupedColumns.Add("parent_class_id"); // grdGrpMemberships.TableDescriptor.Columns["Membership"].GroupByOptions.CaptionText = "{Category} - {RecordCount} Items"; // grdGrpMemberships.TableDescriptor.Columns["Membership"].Width = 0; grdGrpMemberships.TableDescriptor.TopLevelGroupOptions.ShowCaption = false; this works fine, until I uncomment the 2 commented lines either of these lines causes an out of memory exception and reports an error creating the window handle for the child. why is this happening.

Hi Richard, does this also happen with the 3.0 version? Do you have a small sample or can you reproduce this with one of our samples? The error description itsself doesn''t ring any bells on my side. So I can''t tell if it has been fixed. But we made quite a few fixes we made for 3.0. So it is worth a try. Thanks, Stefan

Thanks Stefan, I will try version 3.
