print button of Crystal report 11.5 didnt show pop-up dialog with AJAX

I have developed one web application with ASP.Net 2.0 with AJAX 1.0 and Crystal Report 11.5 Release 2.

When i put Crystal Report viewer in AJAX's update panel, Crystal report viewer is opened properly, but when i try to export or print the report from Crystal Report viewer, it is not showing any dialog box for export or print. Print mode of Crystal report viewer is ActiveX.

Can any body help regarding this problem with example(if possible) ?
