I Used Update Panels to avoid post backs. within page i used grid and one column of grid contains file upload control.

If i am not using update panel then my code runs fine. but when i used update panel my file uploader gets nothing from control.

Dim uploadControl As FileUpload = CType(gvOrderList.Rows(index).FindControl("fileUpdNm"), FileUpload)
