Hi John,
Thank you for your interest in Syncfusion Products.
The header text of the selected cell can be retrieved using TableControlCellClick event of the GridGrouping Control, even when the control is grouped.
void gridGroupingControl1_TableControlCellClick(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellClickEventArgs e)
{
int field = e.TableControl.TableDescriptor.ColIndexToField(e.Inner.ColIndex);
Console.WriteLine(e.TableControl.TableDescriptor.Columns[field].HeaderText);
}
Please have a look at the following sample that illustrates this:
