Dear,

 

When I go to Admin to create new lobby. After that I click Edit to add user for MangerList. But when I click Search on ManagerList it have error. Please help me, why?

 

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.

Thanks you

You shoud add following line in <system.web> section of your web.config file:

 

<pages enableEventValidation="false" />
