Hi , I use Virtual Grid v.4.1.0.4 (beta). I open a dialog form with a GridControl. When I close the form, it does not free the Grid,and when the application exits raises a null reference exception. Only if I dispose the form explicitly, then it does not raise the exception. This problem didn''t appear in v.3.3. (I implement the interfaces IGridModelDataProvider, IGridControlBaseEventsTarget.) I suppose it is related with resetting of volatile data. at Sync.Windows.Forms.Grid.GridModel.get_TableStyle() at Sync.Windows.Forms.Grid.GridControl.get_TableStyle() at Sync.Windows.Forms.Grid.GridControl.get_Font() --------- ! here !------- at System.Windows.Forms.Control.AssignParent(Control value) at System.Windows.Forms.Control.ControlCollection.Remove(Control value) at System.Windows.Forms.Control.Dispose(Boolean disposing) at Sync.Windows.Forms.ScrollControl.Dispose(Boolean disposing) at Sync.Windows.Forms.Grid.GridControlBase.Dispose(Boolean disposing) at Sync.Windows.Forms.Grid.GridControlBaseImp.Dispose(Boolean disposing) at AristonTools.AristonGrid.Dispose(Boolean disposing) at AristonTools.AristonGrid.Finalize() Regards

Hi Stefan, We tried to reproduce this in V4.1 by just implement IGridModelDataProvider interface to the GridControl, but could not get this issue. Maybe I am not following the steps that you are doing. Attached sample working fine here. Can you post a small sample showing this problem or tell us how to see it in the Browser sample/Attached sample? Here is a sample for implementing it. CSIGridModelDataProvider.zip If you can provide more information, we can try to suggest some solution. Regards, Haneef
