I thought this would be easy, but i wasted hours trying to merge cells of a column at a child band. This is what i am doing:

 protected void ugTimesheet_InitializeLayout(object sender, Infragistics.WebUI.UltraWebGrid.LayoutEventArgs e)
        {
            e.Layout.Bands[1].Columns.FromKey("BUTTONCOLUMN").MergeCells = true;
                      
        }

The value in all the cells of this column is the same textvalue. Even then, its not merging them. I can't set to manual merge since the user may add rows to this band.

 Please help.
