WebExcelExporter not working with WHDG.....
posted

Hello,

I have a WHDG that I'm trying to export via the WebExcelExporter. Below is my code. In Internet Explorer, when i click the button to download to excel, I see that the postback is firing the code but, the file that its trying to give me back is "default.aspx" and not the XLS file. When i try it on FireFox, I get the .XSL file to return but in opening the document, i see an empty grid. How do I send the WHDG as is (with out having to refresh the datasource) on the page to the explorter?

Below is my code.
