Turning off the old sort arrow on a column of a GridGroupingControl

[Thabo]

Hi,
I am performing a sort on a column. If i sort the column for the first time in ascending order, i can not perform another sort on the same column in descending order.

How do i turn off the old sort arrow so that i can perform another sort on the same column.

Thanks
David

Here is a code snippet that will initially sort an unsorted column, or reverse the sort if the column is already sorted.

SortColumnDescriptor scd = this.gridGroupingControl1.TableDescriptor.SortedColumns["ParentDec"];
if(scd == null)
{
	this.gridGroupingControl1.TableDescriptor.SortedColumns.Add("ParentDec");
}
else if(scd.SortDirection == ListSortDirection.Ascending)
	scd.SortDirection = ListSortDirection.Descending;
else
	scd.SortDirection = ListSortDirection.Ascending;
