Control disappears after postback when in update panel

Mar 24, 2011 at 4:36 AM

When placed in an update panel, the control disappears whenever a postback is made.

It does work, if its the first load of the page and you upload files they do get uploaded, the problem is that it vanishes after any postback. And I do make an async postback when upload is complete so that I can reload my list of uploaded files.

Has any else experienced this problem? Found a solution?
