Question

I have a GridView that is bound with a dataset. I have my footer, whichis separated by the column lines. I want to merge 2 columns; how do I do that?

<asp:TemplateField HeaderText="Name" SortExpression="Name">
<ItemTemplate>
...  
</ItemTemplate>
<FooterTemplate >                    
Grand Total:
</div>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Age" SortExpression="Age">
<ItemTemplate>
...  
</ItemTemplate>
<FooterTemplate >                    
<%# GetTotal() %> 
</div>
</FooterTemplate>
</asp:TemplateField>

Answer 1

untested code

1st footer template should include <%# GetTotal() %>

2nd footer template should be empty

    Protected Sub Page_SaveStateComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.SaveStateComplete
        Dim DG As GridView = GridView1
            Dim Tbl As Table = DG.Controls(0)
            Dim tr As GridViewRow
            Dim i As Integer
            Dim j As Integer

tr = Tbl.Rows(Tbl.Rows.Count - 1) 'this line assume last row is footer row

                    tr.Cells(0).ColumnSpan = 2 'if you have 3 columns then colspan = 3 instead

                    For j = 1 To 1 'if you have 3 columns then j = 1 To 2 instead
                        tr.Cells(j).Visible = False
                    Next

    End Sub
