Unexplained Error while Exporting Datagrid to Excel

Question

Everything else seems to work ok (e.g. paging, master/detail functions, etc.) but the Export Datagrid to Excel isn't. I get the following:
ErrorWe Recommend:Refreshing the page.Contacting your Portal administrator if problems persist.Accessing this Portlet at a later time.
I am exporting it out as an attachment so Excel opens for the user. It works fine outside of the portal. Anyone know what I'm doing wrong?

I'm using the standard Microsoft ASP.NET 1.1 Datagrid control. Here is my routine that gets launched from a LinkButton Control...
privatevoidExportDataGrid(){Response.Clear();Response.Buffer= true;Response.ContentType = "application/vnd.ms-excel"; Response.AppendHeader("Content-Disposition", "attachment;filename=Lead_FeedBack.xls");Response.Charset = "";
this.EnableViewState = false; System.IO.StringWriter oStringWriter = newSystem.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = newSystem.Web.UI.HtmlTextWriter(oStringWriter);
// Create a DataGrid control and Pass content from first DataGrid to itDataGrid DataGrid2 = newDataGrid();DataGrid2 = DataGrid1;this.RemoveControls(DataGrid2);
//Lets make it a generic looking spreadsheetDataGrid2.HeaderStyle.BackColor = Color.LightGray;DataGrid2.AlternatingItemStyle.BackColor = Color.White;DataGrid2.PagerStyle.BackColor = Color.LightGray;DataGrid2.HeaderStyle.Font.Bold = true;DataGrid2.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString()); Response.End(); }
