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++;
    }

This worked our for me. Trial & error :)

    'VB.NET Code


Private Sub DG_Data_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles DG_Data.RowDataBound
            Try

                'fusion , rowspan , colspan , 
                If e.Row.RowType = DataControlRowType.DataRow Then
                    If e.Row.RowIndex Mod 4 = 0 Then
                        e.Row.Cells(0).Attributes.Add("rowspan", "4")
                    Else
                        e.Row.Cells(0).Visible = False
                    End If
                End If



            Catch ex As Exception
                jq.msgErrorLog(ex)
            End Try
        End Sub

Use RowDataBound event instead:

void GridView31_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow )
    {
        if (e.Row.RowIndex % 4 == 0)
        {
            e.Row.Cells[0].Attributes.Add("rowspan", "4");
        }
        else
        {
            e.Row.Cells[0].Visible = false;
        }
    }
}
