Cgridview Ajax Update/filter Fail

Hi everybody!

I am really getting stuck in a problem I can’t understand.

the problem

Given a certain Model (‘Struttura’: [‘codice_struttura’, ‘codice_regione’, … ])

I am trying to build a custom search page with a jvectormap, some dropdown and a CGridView.

Clicking on the map, users select a region.

A js function will:

  • update one dropdown with the list of cities

  • filter the CGridView by ‘codice_regione’ in order to find the ‘Struttura’ in that region

Currently I can perform an ajax update of the dropdown but I cannot update the CGridView.

the code


        [..some other stuff..]

	<div id="mapData">

		<?php $this->widget('bootstrap.widgets.TbGridView', array(

				'type'=>'striped bordered condensed',




)); ?>


        [..some other stuff..]


        //[..some other stuff..]

	public function actionSearch()


		$uri = Yii::app()->baseUrl . '/js/jquery-jvectormap-1.1.1.css';

		Yii::app()->clientScript->registerCssFile($uri, 'screen, projection');


		$model=new Struttura('search');

		$model->unsetAttributes();  // clear any default values





		$this->render('search', array('model'=>$model));


        //[..some other stuff..]


        [..some other stuff..]

	if(region_id !== false) {

		$.fn.yiiGridView.update("strutture-grid", {data: {codice_regione:region_id}});


        [..some other stuff..]

Firebug console logs:

GET /.../index.php?r=struttura%2Fsearch&codice_regione=16&ajax=strutture-grid

GET /.../index.php?r=struttura/jSbrowse&id=16

When I manually filter the CGridView I get the same GET request

GET /.../index.php?r=struttura%2Fsearch&codice_regione=16&ajax=strutture-grid

obviously in the Model:

	public function search()


		$criteria=new CDbCriteria;


		return new CActiveDataProvider($this, array(




so, why the CGridView doesn’t display filtered data?

Thanks in advance for your help and for all the topics I snooped so far :)
