I’m using SAP’s CrystalReportViewer to display crystal reports using ASP.NET and C#. The print/export functionality works for IE, but not for Chrome.
I’m using Framework 4.
This is the error message.
“Exception Details: System.ArgumentException: 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.”
Could you please help me solve this mystery. I’m complete beginner in ASP.NET, so please try to give me plain advise or solution.
Thanks in advance.
