Hi,

Is it possible to do any HTML like formatting in a group header row?  I'm currently changing the header in GroupSummaryEvaluate event right now.

Thanks!

Hi Kaddy,

Yes, this is possible. You should replace the default content cell in the group header row with a custom one by inheriting from GridGroupContentCellElement. Use the CreateCell event to replace the cell:
void radGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e)
{
    if (e.CellType == typeof(GridGroupContentCellElement))
    {
        e.CellType = typeof(MyGroupCell);
    }
}
 
public class MyGroupCell : GridGroupContentCellElement
{
    public MyGroupCell(GridViewColumn column, GridRowElement row)
        : base(column, row)
    {
    }
 
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(GridGroupContentCellElement);
        }
    }
    public override void SetContent()
    {
        this.DisableHTMLRendering = false;
        this.Text = "<html><b>" + this.Value;
    }
}

I hope this helps.
