Disable Grouping with certain columns

[Aditi Reshma]

I have 3 columns in GGC.Grouping can be done by first 2 column.I have to restrict choosing 3rd column for grouping.ie.,
Product,Group,Member are the three columns.
grouping should be allowed by both product and group.but disable grouping by member.
how can it be done?

Hi Aditi ,

This can be achieved by handling TableControlQueryAllowDragColumn event. You can check for the e.Column for column name and set e.AllowDrag property to false.

See the code:

this.gridGroupingControl1.TableControlQueryAllowDragColumn += new GridQueryAllowDragColumnEventHandler(gridGroupingControl1_TableControlQueryAllowDragColumn);


void gridGroupingControl1_TableControlQueryAllowDragColumn(object sender, GridQueryAllowDragColumnEventArgs e)
{
if (e.Column == "Member")
{
e.AllowDrag = false;
}


}
