I need the data being send from the controller to be displayed on the view..
But unable to do it, any help plss

Answer 1

For ajax returns, you generally would can use renderPartial or echo the results as you have it, but the CHtml::tag functions you would usually pass an HTML object for the tag name, see here or here but it looks like your function is expecting JSON, so you would need to output your results as JSON, see the Yii JSON methods. If that's not the issue, you might need to explain a bit more.

Answer 2

Normally with Yii on ajax button or link or what ever the case might be, you do a on success
array('success'=>'js:function(data) {
jQuery("div#status").html(data);
}
and inside your controller, you can echo the response back to your view. Also make sure you have jQuery loaded in the view!
