colors in grouping grid

[Faraz Haque]

Hi,
Is it possible to use different color for different grouping levels in a grouping grid. I use a caption summary grid, and if i have 3 grouping (summary) levels, each level has the same color. The actual record cells have a different color though. For example if i have a grid with Country , State , city and city population, if i add country and state as grouped cols, and summarize city population, I will get country total and state totals in the same color. I need this to be a bit different.

Any help would be great.

So you have summaries in the group caption row? If so, you can try using QueryCellStyleInfo to color the different levels. Here is code that colors level 1.

private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
	if(e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionSummaryCell)
	{
		GridCaptionRow caption = e.TableCellIdentity.DisplayElement as GridCaptionRow;
		if(caption.ParentGroup.GroupLevel == 1)
			e.Style.BackColor = Color.LightGoldenrodYellow;
	}
}

You can also modify the color for individual grouping levels if you change

GridColumnDescriptor.GroupByAppearance.

For example, if you grouped by "Country" and "Region", you can change the formatting with

grid.TableDescriptor.Columns["Country"].GroupByAppearance.GroupCaptionCell.BackColor = Color.Green;
grid.TableDescriptor.Columns["Region"].GroupByAppearance.GroupCaptionCell.BackColor = Color.Blue;
