Failed to Load Viewstate Problem
Whenever, I try to upload with the RadAsyncUpload control I get the following error.
Is there something I need to do to avoid this problem?
Whenever, I try to upload with the RadAsyncUpload control I get the following error.
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
Is there something I need to do to avoid this problem?
