Problem with file control and Update Panel
Posted on 2009-05-11
I am using file upload control inside the UpdatePanel
But I was not getting the object of fileupload control
then I added following code
where txtSelectVideo is the ID of File upload control
But Now I am getting an error
Control with ID 'txtSelectVideo' being registered through RegisterAsyncPostBackControl or RegisterPostBackControl must implement either INamingContainer, IPostBackDataHandler, or IPostBackEventHandler.
