I have a grouping grid with the ShowGroupDropArea set to true. I don''t like the dark gray colors of that area. How can I set my own colors? Also, I''ve set the ListBoxSelectionMode to One and the row highlights with a black background. How can I change this color?

1) The droparea is a little grid. So, you can handle its PrepareViewStyleInfo event, and explicitly set a backcolor there. this.gridGroupingControl1.GridGroupDropArea.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(GridGroupDropArea_PrepareViewStyleInfo); //the handler private void GridGroupDropArea_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e) { e.Style.BackColor = Color.Red; } 2) Make sure the AllowSelections property includes the AlphBlend flag. gcc.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended; gcc.TableOptions.AllowSelection = GridSelectionFlags.Any;

Thanks Clay, I tried your code to change the droparea''s background color and it worked...sort of. The problem remains that if I resize the form, the droparea''s background color (red) does not fill the complete band (at the top of the grid). It looks like the droparea is painted red for the form''s initial size, but, upon resizing the form larger, the droparea band is both red and dark gray. Is there anyway to have the entire droparea''s background color to be one color? Also, I set the Alphablend flag on but now I get no row highlight at all! What am I doing wrong? >1) The droparea is a little grid.

Try setting these two properties. this.gridGroupingControl1.GridGroupDropArea.Dock = DockStyle.Fill; this.gridGroupingControl1.GridGroupDropArea.Model.Properties.BackgroundColor = Color.Red; Here is a sample with the alpha blend selection set ok as well as coloring teh drop area. GGC_9672.zip
