Hi Michael,
To change the apearance in the GridGroupDropArea, you need catch the PrepareViewStyleInfo event of the GridGroupDropArea. Please try the below code.
// form load
gridGroupingControl1.GridGroupDropArea.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(GridGroupDropArea_PrepareViewStyleInfo);
void GridGroupDropArea_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
if (this.gridGroupingControl1.TableDescriptor.GroupedColumns.Count > 0)
{
e.Style.BackColor = Color.BurlyWood;
e.Style.TextColor = Color.White;
e.Style.Borders.All = new GridBorder(GridBorderStyle.None);
}
}
Let me know if you have any other questions.
Have a nice time.
Regards,
Rajagopal
