Formatting rows as summary

[Jason]

I am using a grid with bound rows and a summary row.  I would like to also format one of the bound rows to look like a summary row.
Is there a simple way to do this?

I've tried setting the cell element ThemeRole to "GridSummaryCellElement" in the CellFormatting event, but it didn't work

Hello Jason,

Thank you for writing.

In order to achieve your goal, you can use the RowFormatting event and apply custom formatting to RadGridView's data rows. Summary row elements have specific BackgroundShape. Here is a sample code snippet demonstrating how to extract the RadImageShape from the theme and set it to a specific data row by using the RowFormatting event:

RadImageShape shape = null;

private void Form1_Load(object sender, EventArgs e)
{
    Theme theme = ThemeRepository.FindTheme("ControlDefault");
    StyleRepository rowRepository = theme.FindRepository("GridSummaryRowImageShape");
    shape = rowRepository.FindSetting("BackgroundShape").Value as RadImageShape;

    GridViewSummaryItem summaryItem = new GridViewSummaryItem();
    summaryItem.Name = "CategoryName";
    summaryItem.Aggregate = GridAggregateFunction.Count;

    GridViewSummaryRowItem summaryRowItem = new GridViewSummaryRowItem();
    summaryRowItem.Add(summaryItem);

    this.radGridView1.SummaryRowsTop.Add(summaryRowItem);
    this.radGridView1.SummaryRowsBottom.Add(summaryRowItem);

    this.categoriesTableAdapter.Fill(this.nwindDataSet.Categories);
}

private void radGridView1_RowFormatting(object sender, RowFormattingEventArgs e)
{
    if (e.RowElement.RowInfo.Index == 3 && shape != null)
    {
        e.RowElement.BackgroundShape = shape;
    }
    else
    {
        e.RowElement.ResetValue(LightVisualElement.BackgroundShapeProperty, ValueResetFlags.Local);
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.
