Answer 1

 protected void GridView31_DataBound1(object sender, EventArgs e)
{
    int i = 1;
    for (int rowIndex = grdView31.Rows.Count - 2; rowIndex >= 0; rowIndex--)
    {
        GridViewRow gvRow = grdView31.Rows[rowIndex];
        GridViewRow gvPreviousRow = grdView31.Rows[rowIndex + 1];

        if (i % 4 !=0)
        {
            if (gvPreviousRow.Cells[0].RowSpan < 2)
            {
                gvRow.Cells[0].RowSpan = 2;
            }
            else
            {
                gvRow.Cells[0].RowSpan = gvPreviousRow.Cells[0].RowSpan + 1;
            }
            gvPreviousRow.Cells[0].Visible = false;
        }
        i++;
    }
