Hi Friends,

I have Grid View inside grid i have no of records.but i want to change or edit selected row in grid.so i want to display all data in to text boxes and dropdownlist .I displayed those to but i need to display fileupload control to update file name.


Here small thing when i edit data without fileupload they get error like

Access to the path 'D:\Venkat\Venkat.s\VENKAT\Dmst\documents' is denied.

But i don't select any file in fileupload.thats why i get error, then i selected file then it ll be ok.

Thanks&Regards
