Hi Mitul,
You could try handling TableControlCurrentCellChanged event and check for the ExtraSection to catch the changes.
private void gridGroupingControl1_TableControlCurrentCellChanged(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlEventArgs e)
{
Syncfusion.Grouping.Element element = e.TableControl.Table.DisplayElements[e.TableControl.CurrentCell.RowIndex];
if(element is ExtraSection)
{
Console.WriteLine("Editing");
}
}
Here is a small sample:
