Not Solved how to call back and post back.
hi
i put this line also
Code:
<pages enableEventValidation="false"/>

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

You also need to set validateRequest to false as below
Code:
<pages validateRequest="false" enableEventValidation="false" />

if you are using ajax script, then also, make sure - Scriptmanagers partial rendering is enabled
