To customize a form or grid behavior you can create an own custom class that overrides methods or adds custom buttons/actions/whatever.

The example below is for a form, but works the same for a grid.

First you have to define the new class, inheriting from Kwf.Auto.FormPanel:

Example.FooForm = Ext.extend(Kwf.Auto.FormPanel, {
    initComponent: function() {
        //add custom code here or override other methods;
Ext.reg('example.fooform', Example.FooForm);

Then the class needs to be used:

  1. Using xtype in indesAction()

    public function indexAction()
        $this->view->xtype = 'example.fooform';
  2. Create directly in javascript

    Example.FooPanel = Ext.extend(Ext.Panel, {
        initComponent: function() {
           //instead of creating a Kwf.Auto.FormPanel use custom class
            var fooForm = new Example.FooForm({
                 controllerUrl: '...'
