Merge common Cell of first column in Datagridview

HI,
if you want to group the name column add the below method and pass the paramters to after data bind event


groupGridView(gridviewname,0,2,"Name");


 public void groupGridView(GridViewRowCollection gvrc, int startIndex, int total, string labelName)
    {
       
        if ((total <= 0) || (gvrc == null) || (gvrc.Count == 0) )
        {
            return;
        }

        int i, count = 1;
        Label ctrllbl, nextlbl;
        ArrayList lst = new ArrayList();
        lst.Add(gvrc[0]);
        var ctrl = gvrc[0].Cells[startIndex];
        ctrllbl = (Label)gvrc[0].Cells[startIndex].FindControl(labelName);
        var prevControl = gvrc[0].Cells[0];
        for (i = 1; i < gvrc.Count; i++)
        {
            TableCell nextCell = gvrc[i].Cells[startIndex];
            TableCell prevCell = gvrc[i].Cells[0];
            nextlbl = (Label)gvrc[i].Cells[startIndex].FindControl(labelName);

            if (nextlbl != null && ctrllbl != null)
            {
                if (ctrllbl.Text == nextlbl.Text)
                {
                    count++;
                    nextCell.Visible = false;
                    prevCell.Visible = false;
                    lst.Add(gvrc[i]);
                }
                else
                {
                    if (count > 1)
                    {
                        ctrl.RowSpan = count;
                        prevControl.RowSpan = count;
                        groupGridView(new GridViewRowCollection(lst), startIndex, total - 1, labelName);
                    }
                    count = 1;
                    lst.Clear();
                    ctrl = gvrc[i].Cells[startIndex];
                    prevControl = gvrc[i].Cells[0];
                    ctrllbl = (Label)gvrc[i].Cells[startIndex].FindControl(labelName);
                    lst.Add(gvrc[i]);
                }
            }


        }
        if (count > 1)
        {
            ctrl.RowSpan = count;
            prevControl.RowSpan = count;
            groupGridView(new GridViewRowCollection(lst), startIndex, total - 1, labelName);
        }
        count = 1;
        lst.Clear();
    }
