有没有办法让CGridView 不在其所在的视图的初始渲染上加载数据,而是在初始页面加载后使其加载第一页以及后续的AJAX请求?
这主要用于性能优化。有一个数据模型在CGridView背后相当缓慢,我希望能够以一种快速的方式加载页面,然后在几秒钟之后通过AJAX请求加载数据。

您可以按如下方式修改操作:
public function actionIndex() {
$dataProvider = new CActiveDataProvider('User'); // The dataprovider your grid uses
if (!$this->isAjaxRequest()) {
$dataProvider->criteria->addCondition('1 = 0'); // You could also use 0, but I think this is more clear
}
[...]
}
然后在javascript部分的视图中:
$(function() { // If you are using jQuery this is executed when the page is loaded
$.fn.yiiGridView.update("{id-of-your-grid-view}");
});

Brewer Gorge非常接近,并且由于他建议的答案,它让我走上正轨。这有效:
// Controller, after creating $dataProvider, before calling $this->render...
if (!Yii::app()->request->isAjaxRequest) {
$dataProvider->criteria->addCondition('1 = 0');
}
// View
<script type="text/javascript">
$(window).load(function() {
$('#id-of-grid').yiiGridView('update');
});
</script>

只需在控制器中编写代码,如下所示:
$model= new Data('search');
$model->unsetAttributes();
if(isset($_GET['Data']))
$model->attributes = $_GET['Data'];
if (!Yii::app()->request->isAjaxRequest)
$data->id=0; //or something that sure model return empty
