Details grid view refreshes the whole page unexpectedly

I have a grid view and details view. My details view is in the update panel and it should be displayed for edits of the gridview. I have a file Upload control inside detailsview, Now when I click the upload button the whole page gets refreshed.

What do I do and where do I do? I think it should be some problem with t开发者_如何学Pythonhe postback triggers.

I think , you must post back when uploading a file, but try to do the following:

in the file uploader event : call the following method:

updatepanelName.Update();

If, it should not get refreshed then use the AutoPostBack= false in Upload control.
