I've setup a gridview with extra fields in the footer to allow inserts.  My problem is, that if the sqldatasourcr contains no records the gridview does not display and thus the footer does not, so I can't insert any new records.
What do I do?

A couple of ways either define an emptydatatemplate :

<asp:gridview id="CustomersGridView"  
        datasourceid="CustomersSqlDataSource"  
        autogeneratecolumns="true" 
        runat="server"> 
 
        <emptydatarowstyle backcolor="LightBlue" 
          forecolor="Red"/> 
 
        <emptydatatemplate> 
 
          <asp:image id="NoDataImage" 
            imageurl="~/images/Image.jpg" 
            alternatetext="No Image"  
            runat="server"/> 
 
            No Data Found.   
 
        </emptydatatemplate>  
 
      </asp:gridview> 

Open in new window


or you can put in a dummy row if nothing is returned and then hide it:

    Protected Sub Page_PreRenderComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRenderComplete 
        If gvSites.Rows.Count = 0 Then 
            AddDummySiteRow() 
        End If 
    End Sub

    ''' <summary> 
    ''' Create a dummy hidden row so that the title bar columns remain 
    ''' </summary> 
    ''' <remarks></remarks> 
    Private Sub AddDummySiteRow() 
        Try 
            Dim lstDummy As New Collections.Generic.List(Of JEMSConfiguration.BLL.Site) 
            lstDummy.Add(New JEMSConfiguration.BLL.Site) 
            gvSites.DataSourceID = "" 
            gvSites.DataSource = lstDummy 
            gvSites.DataBind() 
 
            With gvSites.Rows(0) 
                ' hide the delete and edit buttons 
                .Cells(0).Controls(1).Visible = False 
                .Cells(0).Controls(3).Visible = False 
 
                ' hide the labels displaying the dummy data 
                .Cells(1).Controls(1).Visible = False 
                .Cells(2).Controls(1).Visible = False 
                .Cells(3).Controls(1).Visible = False 
                .Cells(4).Controls(1).Visible = False 
            End With 
 
        Catch ex As Exception 
            Throw 
        End Try 
    End Sub

Well  , the requirement as I mentioned, is that, I should be able to use the Insert button and show the footer template, so i can add my first record, does it makes sense?

I actually tried pasting the html code generated from the page, but could not make the insert button work since, it looks for the
.FooterRow.FindControl("txtNT1Census")).Text;

Yes and if you use one of the techniques in my last post the footer will be shown.
