GridGroupingControl.TableModel.Options.NumberedRowHeaders

[Daniel Chait]

When I set

gridGroupingControl1.TableModel.Options.NumberedRowHeaders = true;

I expected that instead of the little triangle thingy on the current record I would see row numbers there... like Excel... but it doesn''t work.

Daniel,

The GridTableRowHeaderCellRenderer (RowHeaderCell celltype) ignores this setting since it does not make sense to display the underlying row index in most cases. Row 1 will be the column headers and records would be offset.

What is better is if you display the record index instead. You can do this by handling the TableControlPrepareViewStyleInfo event and specify "Header" as cell type.

this.groupingGrid1.TableControlPrepareViewStyleInfo += new GridTableControlPrepareViewStyleInfoEventHandler(groupingGrid1_TableControlPrepareViewStyleInfo);

private void groupingGrid1_TableControlPrepareViewStyleInfo(object sender, GridTableControlPrepareViewStyleInfoEventArgs e)
{
	GridTableCellStyleInfo style = (GridTableCellStyleInfo) e.Inner.Style;
	if (style.TableCellIdentity.TableCellType == GridTableCellType.RecordRowHeaderCell 
		|| style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordRowHeaderCell)
	{
		Record r = style.TableCellIdentity.DisplayElement.ParentRecord;
		int recordIndex = r.ParentTable.Records.IndexOf(r);

		string displayText = recordIndex.ToString();

		e.Inner.Style.CellValue = displayText;
		e.Inner.Style.CellType = "Header";
	}
}

Thanks... what''s the difference between

groupingGrid1.TableControlPrepareViewStyleInfo

and

gridGroupingControl1.QueryCellStyleInfo

They seem like they accomplish similar things, no? If I already have code in QueryCellStyleInfo will it clobber the other?
