This error is coming on vb.net please give suggestion

Hi Rupesh,

<%@ Page EnableEventValidation="true" %>

This code snippet enables event validation in a VB web application. Event validation is a security feature that ensures that postback or callback arguments originate from the server control that originally rendered them. It helps prevent certain types of attacks, such as cross-site scripting (XSS) attacks.

By setting EnableEventValidation to true, the page will validate the postback or callback data to ensure its integrity and origin. If the data is not valid or expected, an "Invalid postback or callback argument" error will be thrown.

To register the postback or callback data for validation, you can use the ClientScriptManager.RegisterForEventValidation method. This method allows you to explicitly specify the valid values for the event arguments, preventing any unauthorized modifications.

are you dynamically adding controls to your page ?
