                                  • Hi.
                                    Found a bug when moving the AgDatagrid between different Panels (compact/full view modes).

                                    I would also appreciate some kind of temporary workaround for this, when moved I would like to keep the grouped columns and have the same grouped rows expanded as before.

                                    Best regards
                                    /Ralf

                                Hi Ralf,

                                Thank you for the report, and for providing the sample project.

                                I've reproduced the problem locally, and we'll examine why it occurs.

                                As an immediate solution, please surround the code that changes the grid's parent with the BeginUpdate/EndUpdate pair:

                                	
                                [C#]
                                aggrid.BeginUpdate();            
            if (grd1.Children.Count == 0)
            {
                grd2.Children.Clear();
                grd1.Children.Add(aggrid);
            }
            else if (grd2.Children.Count == 0)
            {
                grd1.Children.Clear();
                grd2.Children.Add(aggrid);
            }
            aggrid.EndUpdate();

                                This should "fix" the problem.

                                Thanks,
                                Vito
