File Upload will not work with a partial post back.

Use PostBackTrigger instead as a trigger and it should work fine.

I am changing a project which I didn't created myself. the developer had some terrible implementation on this project. specifically he put the contentplaceHolder of master page in an updatePanel so I can not use PostBackTrigger. Is there another solution?

Sorry for late reply but I just saw your post.
You might have to use AsyncFileUpload in AjaxControllToolkit (3rd answer in the above mentioned link). If that doesn't help, try using jQuery file upload plugin.
