but updateprogress is not working thansk

You need to have a Post Back Trigger if you want to use a File Upload in the Update Panel.

From the documentation (http://www.asp.net/ajax/documentation/live/overview/UpdatePanelOverview.aspx), File Upload controls are not compatible with UpdatePanel Controls.

Try to use <input type= "File" id="fileUpload" name="fileUpload" />
