Grid Grouping Control

[Troy]

Is there a way to have the GridGrouping control +/- boxes have a default to expanded rather than collapsed when grouping by a specific column?

You can handle the TableDescriptor.GroupedColumns.Changed event.

this.gridGroupingControl1.TableDescriptor.GroupedColumns.Changed += new Syncfusion.Collections.ListPropertyChangedEventHandler(GroupedColumns_Changed);

private void GroupedColumns_Changed(object sender, Syncfusion.Collections.ListPropertyChangedEventArgs e)
{
	if(e.Action == Syncfusion.Collections.ListPropertyChangedType.Add 
		|| e.Action == Syncfusion.Collections.ListPropertyChangedType.Insert
		&& e.Item != null)
	{
		SortColumnDescriptor scd = e.Item as SortColumnDescriptor;
		if(scd != null && scd.Name == "Col1")
			this.gridGroupingControl1.Table.ExpandAllGroups();
	}
}
