beforeAjaxUpdate on delete cgridview yii - php

Question

Here is my code
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'dsfsd',
'dataProvider' => $model->search(),
'filter' => $model,
'cssFile' => false,
'itemsCssClass' => 'table table-striped',
'beforeAjaxUpdate'=>'js:function(id,options){$.blockUI({
message: "Please wait",
//showOverlay: false,
css: {
border: "none",
padding: "15px",
"-webkit-border-radius": "10px",
"-moz-border-radius": "10px",
opacity: 1,
"z-index": "9999"
}
});}',
'columns' => array(
array(
'header' => '#',
'name' => 'id',
'type' => 'raw',
'value' => 'CHtml::link(CHtml::encode($data->id),array("abc/m/".CHtml::encode($data->id)."/info"))',
'htmlOptions' => array('width' => '40px'),
'filter' => CHtml::activeTextField($model, 'id', array('placeholder' => 'search by id')),
), array(
'header' => 'First name',
'name' => '$data.user.f_name',
'type' => 'raw',
'value' => 'CHtml::encode($data->user->f_name)',
), array(
'header' => 'Last name',
'name' => '$data.user.l_name',
'type' => 'raw',
'value' => 'CHtml::encode($data->user->l_name)'
),
array(
'class' => 'CButtonColumn',
'template' => '{update} {delete}',
//'updateButtonUrl' => 'Yii::app()->createUrl("abc/xyz?id=".$data->id."&c_id=".$data->c_id)',
'deleteButtonUrl' => 'Yii::app()->createUrl("xyv/abc",array("uid"=>$data->id))',
),
),
));
Well, what I want is that the operations under beforeAjaxUpdate will work only when delete button is clicked, not for any other ajax actions like on search or update. How is it possible?

You can add callback function to delete button:
http://www.yiiframework.com/doc/api/1.1/CButtonColumn#buttons-detail
You should set click option in buttons config array:
'columns' => array(
...
'buttons'=>array(
'class'=>'CButtonColumn',
'template'=>'{delete}{update}',
'buttons'=>array(
'delete'=>array(
'click'=>'function(){/*your code here*/}'
)
)
)
...
)
You can return false from callback function to prevent deleting.
