How do I use ASP.NET File upload control inside AJAX Update panel?

Can you use ASP.NET File Upload control inside the AJAX Update Panel without any difficulty? Actually, ASP.NET File upload control requests full post back to post the file to server. So, when you put File upload control inside the AJAX Update panel, it will return null value as a post file.

So, what is the solution for this? Yes, you can define post back trigger to fire full page post back. I hope you realized the set-up behind this and next time I will post about “How do I use ASP.NET File upload control inside the GridView + Update Panel?”
