Hi

A gridview works with many models and I suppose ClistView does the same.

First your have the main $model - which is used to call the search() function to create the dataprovider.

The dataprovider also contains many models - one for each gridview row. They are called $data in each row.

Since each row in the gridview uses its own model (called $data) it does not help to store your total in $data, because the next row will not use the same $data.

If you want to store your total in such a way that ALL rows can access it, then you have to store it in the main $model.

Have a look at this wiki.

HI,

I am not sure about the following but may help you.

In While loop we use an increment variable suppose i and do i++ at the end.

Same way you may follow by having a variable and use it inside your _view of listing to add up the total, like you variable is $totalofAll= 0 in code calling the listview than inside listview you will do $totalofAll+$data->amount.

Let me know it helps or you need further.

Hello,

Here i find my solution.




class AbcController extends Controller

{

    public $total=0;

}

and then use it in your renderPartial _view.php like




$this->total += $data->amount(value 100);

Hope it helps you. see link
