I am updating a page to no longer user any postbacks by using the RadAjaxManager. Previously, in my code-behind, I had captured a return value and embedded javascript code on the page based on the return value to display a message to the user. Now that I am using RadAjaxManager and eliminated postbacks, everything is working fine except that it does not show the message to the user. What is the best way to do this if I am capturing the return value in the code-behind?
