ASP.NET FileUpload in UpdatePanel - still not working

Question

Attempting to use a FileUpload or AsyncFileUpload control in an updatepanel on a NET 4.5/C# web application.

I\'ve tried using either standard Scriptmanager or ToolK

Answer 1

File Upload will not work with a partial post back. It requires full page request. So add the below line in your page load.

ScriptManager.GetCurrent(this).RegisterPostBackControl(this.YourControlID);
