1) Verify whether UpRSPictureedt has a RUNAT=server attribute. Custom manually typed controls normally, we skip and create this error.
2) upload1.PostedFile should be checked for NULL

Or you can output your data to an HTML table in the page and then add headers to get explorer to open that item in Excel.

Please check out whether all the tags are being closed i.e all the start tags have its corresponding end tags.. if so then there'll be no such errors..

Put a UpdatePanel, and drag your drop down control inside to that. You are almost done
