Asked On June 23, 2005 10:55 AM

Can you please provide a simple code example on how to find the rows in the underlying data table that corresponds to the current selection in the grouping grid? (If the selection is a block of cell, I want all rows intersecting this block.) I find it a bit difficult to figure out this from the doc. I am using TableOptions.AllowSelection = GridSelectionFlags.Any; TableOptions.ListBoxSelectionMode = SelectionMode.None; Thanks.

This worked for me using a flat table.
private void button1_Click(object sender, System.EventArgs e)
{
	GridTableControl tc = this.gridGroupingControl1.TableControl;
	foreach(GridRangeInfo range in tc.Selections.Ranges)
	{
		GridRangeInfo range1 = range.ExpandRange(1, 1, tc.Model.RowCount, tc.Model.ColCount);
		for(int row = range1.Top; row <= range1.Bottom; ++row)
		{
			GridTableCellStyleInfo style = tc.Model[row, range1.Left];
			if(style.TableCellIdentity.DisplayElement != null 
				&& style.TableCellIdentity.DisplayElement.ParentRecord != null)
			{
				DataRowView drv = style.TableCellIdentity.DisplayElement.ParentRecord.GetData() as DataRowView;
				if(drv != null)
				{
					Console.WriteLine("{0}  {1}  {2}  {3}", drv[0], drv[1], drv[2], drv[3]);
				}
			}
		}
	}
}

Just what I was looking for. Thanks a lot! One more question: If I have got a TableDescriptor from the grid (may be the TableDescriptor for a foreign key table), how do I found the underlying ADO DataTable?

Try TableDescriptor.Name.
