Getting this on submit button click

Invalid postback or callback argument. Event validation is enabled
using 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."

Click event is not occurring.

Please Help!
