I have three fileupload controls using multiple images upload. Now I need to disable fileupload2, fileupload3 ect... whenever empty data in fileupload1, after I need to enable fileuploadcontrol1. If fileupload1 & fileupload2 have data after fileupload3 will be enabled.
Note: I think it's correct way to upload multiple images using fileupload control, if you anyone please tell me the other way to upload multiple images.
Please help me.........
Thanks in advance.
