Upload control in a Wizard in an Update Panel. How to add the trigger dynamically?

I have an update panel surrounding a Wizard control. One of the steps in that wizard is that the user can upload photos. So what I want to do is add a trigger to force a full postback on the upload step.

Is this at all possible? I'm having troubles obtaining the correct ControlID to add on the trigger...

Hi.

FileUpload is not supported with ASP.NET AJAX .because that you cann't use it and you cann't find it with ControlID's!

Create a Button Control and set this as a PostBack trigger forupdatePanel. In the Button Click event save the file from File uploadcontrol.

Thank you for the suggestion. I'll give it a go!
