Programatically do grouping, and detect user-grouping

[Dominic Morris]

Hi,

I''d like to programatically setup the grouping grid to group by a given column. How is this done?!

Also, I''d like to detect when the user alters the grouping manually by dragging a column header; what event fires when this happens?

The reason for the second request, is that when I set TableDescriptor.ChildGroupOptions.ShowCaptionSummaryCells = true, the grouped row containing the +- icon needs its width increased to show the group text; I need to do this programatically in response to the grouping changing.

Thanks,
D.

To programmitically group by a column, you add the column to the GroupedColumns collection.

this.gridGroupingControl2.TableDescriptor.GroupedColumns.Add("Col2");

To ne notified of the user do a grouping, you can subscribe to the GroupedColumns.Changed event.

private void GroupedColumns_Changed(object sender, ListPropertyChangedEventArgs e)
{
	SortColumnDescriptor dc = e.Item as SortColumnDescriptor;
	Console.WriteLine(dc.Name + " "  + e.Action.ToString());
}
