Grid Excel Export works in visual studio debug mode but not normally

[Indy]

Hi
I have an an asp.net radgrid using webforms.  The Excel export seems to work in debug mode when in visual studio but faisl when in environment.  If I debug I can see the items being hit via debug/watch window and all works well.  Any idea why it does not work when not in debug mode.  Please see below sample code:

 

<ClientSettings ReorderColumnsOnClient="False" AllowDragToGroup="False" AllowColumnsReorder="False">
<Selecting AllowRowSelect="True" />
 </ClientSettings>
<ExportSettings IgnorePaging="true" OpenInNewWindow="true" ExportOnlyData="true" >
<Excel Format="ExcelML" AutoFitImages="true" />
<Pdf PageHeight="210mm" PageWidth="297mm" DefaultFontFamily="Arial Unicode MS" PageBottomMargin="5mm" PageTopMargin="5mm" PageLeftMargin="5mm" PageRightMargin="5mm" />
</ExportSettings>


With GridView1
.ExportSettings.FileName = "ProjectTrackerAt" & Now().ToString("dd-MMM-yy")
.ExportSettings.IgnorePaging = True
.ExportSettings.OpenInNewWindow = True
.HeaderStyle.Font.Bold = True
.ExportSettings.Excel.Format = GridExcelExportFormat.Html
.MasterTableView.ExportToExcel()
End With

I finally managed to work this out - it was because my page was not identified in the URL eg my URL was:

http://localhost/WebSiteName/SubDirectory/

The above goes to default.aspx

However if the raw url is http://localhost/WebSiteName/SubDirectory/default.aspx then the Export works fine
