Export DataGrid to Excel

Question

I have this code to export DataGrid to Excel: Response.Clear() Response.Buffer = True Response.ContentType = "application/vnd.ms-excel" Response.Charset = "" Me.EnableViewState = False Dim datiExcel As String Dim SW As System.IO.StringWriter = New System.IO.StringWriter() Dim HTW As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(SW) DataGrid1.RenderControl(HTW) Response.Write(SW.ToString()) Response.End() This code works well but how is possible to export in a new window different from the page of datagrid? Thanks
