Hi,

I am trying to export a datagrid to an excel sheet. I found this code at the following location:http://codebetter.com/blogs/darrell.norton/archive/2004/02/12/7154.aspx

 ' Set the content type to Excel
        Response.ContentType = "application/vnd.ms-excel"

        'Turn off the view state
        Me.EnableViewState = False

        'Remove the charset from the Content-Type header
        Response.Charset = String.Empty

        Dim myTextWriter As New System.IO.StringWriter
        Dim myHtmlTextWriter As New System.Web.UI.HtmlTextWriter(myTextWriter)

        'Get the HTML for the control
        dg_disp.RenderControl(myHtmlTextWriter)

        'Write the HTML to the browser
        Response.Write(myTextWriter.ToString())

        'End the response
        Response.End()

The problem is that I have a checkbox in my datagrid and I get the following error when I run it:
Control 'dg_disp__ctl2_cbSelect' of type 'CheckBox' must be placed inside a form tag with runat=server.

If I remove the checkbox it will export the data. Does anyone know of a way that I can export the rest of the data in the grid without exporting the checkbox? I would appreciate the help. Thank you!

Actually add this to your code behind.

Public Overrides Sub VerifyRenderingInServerForm(ByVal control As
Control)

End Sub

Okay, I'm sorry, but where do I need to put this exactly. I tried to place it in my code behind and it said:
sub VerifyRenderingInServerForm shadows an overloadable member declared in the base class "Page". If you want to overload the base method, this method must be declared 'Overloads'.
