I have a update panel where first is a Next button and then Submit. When clicking Submit it is showing fileload HasRows property false. Whats the reason

It should show some files in upload control

  • why you are using HasRows to check fileupload have any files or not. you can check it by fileUploader.HasFile – Kevin Shah Jun 07 '19 at 09:15

  • I mean same fileUploader.HasFile is giving false result even if I am selecting files. – Anurag Singh Jun 07 '19 at 10:51

I got the answer

In Page_Load add: Page.Form.Attributes.Add("enctype", "multipart/form-data");

This is working when there is multipart form
