changing cell color at startup

[Clario Menezes]

Hi,

I''d like to initialize the color of a set of cells based on their grouping grid coordinates, but I don''t want to affect the color of the group header rows/columns in the process. Here''s what I''d like to say in my TableControlPrepareViewStyleInfo handler:

int row = e.Inner.RowIndex;
int col = e.Inner.ColIndex;

if ((col >= 4 && row <= 5) && "cell is not some sort of header")
{
e.Inner.Style.BackColor = Color.LightGoldenrodYellow;
}

Any ideas on how I can accomplish this would be greatly appreciated.

Thank you,

Clario

Hi Clario,

Try code like this instead:

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

		GridColumnDescriptor column = style.TableCellIdentity.Column;
		
		if (column.TableDescriptor.Columns.IndexOf(column) == 4)
			e.Inner.Style.BackColor = Color.Red;
	}
}

Not sure about this one but check out also the GridEngine.AllowCacheStyles property which we added for 2.1. Then you could do the coloring also in QueryCellStyleInfo.

Then option forces GridRecordRow and GridCaptionRow elements to keep a cache with style information for individual cells and reduce the number of QueryCellStyleInfo calls being raised for this cells.

Thanks a lot, Stefan! The code you sent worked very well.
