Kendo Grid Filter Posting Twice

Hello Tony,

The second filter will be sent because the built-in filter menu will still filter the dataSource if the default action is not prevented. You should call the event argument preventDefault method to prevent the form from submitting in order to stop the built-in filter. Since the event will not be handled in this case by the built-in logic, you also will need to manually close the popup. The scenario is demonstrated in this example.

Regards,
Daniel
