Thanks for getting back to me gep13. Yeah, thats what I thought. It doesn't appear to be the case though. This is the code that I am using for a Gridview Export;

Code:
 Public Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
          End Sub
Then, within the export button function;
Code:
Dim sw As StringWriter = New StringWriter()
        Dim htw As HtmlTextWriter = New HtmlTextWriter(sw)

        Response.Clear()
        Response.ContentType = "application/ms-excel"
        'Response.ContentType = "application/vnd.excel"
        Response.Charset = ""
        Response.AddHeader("content-disposition", "attachment;filename=" & Me.txt_SReference.Text & ".xls")

        'Bind the dataset to the datagrid, to export the same to excel
        Me.grd_order.RenderControl(htw)
        
        'Replace the hyperlinks
        Response.Write(Regex.Replace(sw.ToString(), "(<a[^>]*>)|(</a>)", " ", RegexOptions.IgnoreCase))
        Response.End()
