CGridview filter on page load with pre define value in search field - yii

Question

I am working with the Yii framework.
I have set a value in one of my cgridview filter fields using:
Here is my jQuery to assign a value to the searchfield:
$('#gridviewid').find('input[type=text],textarea,select').filter(':visible:first').val('".$_GET['value']."');
And here my PHP for calling the cgridview:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'bills-grid',
'dataProvider'=>$dataProvider,
'filter'=>$model,
'cssFile'=>Yii::app()->baseUrl . '/css/gridview.css',
'pager'=>array(
'class'=>'AjaxList',
'maxButtonCount'=>25,
'header'=>''
),
'columns' => $dialog->columns(),
'template'=>"<div class=\"tools\">".$dialog->link()." ".CHtml::link($xcel.' Export to excel', array('ExcelAll'))."</div><br />{items}{summary}<div class=\"pager-fix\">{pager}</div>",));
The value appears in the search field and my cgridview works correctly without any issues, but I am unable to trigger the cgridview to refresh or filter. Does anyone know who to trigger the cgridview to filter after page load with a predefined value?
Any help would be greatly appreciated and please let me know if you need additional information.
Thank you.

You can solve the problem without any clientside code modification. In your controller action just set the default value for the attribute as shown below
public function actionAdmin()
{
$model = new Bills();
$model->unsetAttributes();
$model->attribute_name="default filter value";//where attribute_name is the attribute for which you want the default value in the filter search field
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('admin',array('model'=>$model));
}

Have a look at 'default' index action that gii generates:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('index',array('model'=>$model));
}
So if you add one line like: $model->attribute = 'test';, you're done. 'attribute' is of course the attribute that has to have the default filter value (in this case value is 'test') :). So your code looks like:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
if(!isset($_GET['Bills']['attribute']) {
$model->attribute = 'test';
}
$this->render('index',array('model'=>$model));
}
Of course youre attribute will have a test value (in filter) set up as long as you wont type anything in its filter field. I hope that that's what you're looking for. Your filter should work as always.
Sorry for my bad english :)

You can use Yii's update:
$.fn.yiiGridView.update('bills-grid', {
type: 'GET',
url: <?php echo Yii::app()->createUrl('controller/action') ?>"?Class[attribute]=<?php echo $_GET['value'] ?>
success: function() {
$.fn.yiiGridView.update('bills-grid');
}
});
This is how i do it, just change the URL, it should be the same controller action of the gridview and change URL parameters to the structure represented in there, should be like Bills[attribute]=value.
