I am using VS-2005.
In my website I have used the html input control with type=file.
The problem is that when I place this control inside an 'UpdatePanel' the 'PostedFile' property becomes 'Nothing' on postback. So in order to get things working I have removed the 'UpdatePanel' and things are working fine.
However, I am interested to know what kind of workaround is required if I were to use an 'UpdatePanel'? In one of the threads at forums.asp.net I found that we need to set a 'PostBackHandler' for the update panel. I have no idea how to implement this. Does it refer to 'AsyncPostbackTrigger' or 'SyncPostBackTrigger'?
Can someone give an idea how to implement this?
