Hello,

i have a one error when masterpage linkutton is clicked. i use script manager on one page and it is use master page. there is no script manager in Master page.

error is :

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.

Please help Me..

Thanks in Advance.

This is because while requesting to server i.e.while postback the compiler getting some tag like sysntax or some invalid operator so it is showing problem.so you can check your attributes at page directive
To solve these problems we used to add CDATA section but that is not good idea,try placing ScriptManager on Master page or change the attribute.

when i put script manager in master page so it next inherited page it will not allow to put next script manager because i want to use updateprogress on next inherited page. Please Correct if i am wrong.

It does not matter. As long as you are using Master Page as the Master for all your ASPX pages ScriptManager can be present in Master Page and you can always use UpdateProgress in those pages.
