How to change url of back button in grid form in admin of magento?

Question

I am working Magento community edition 1.7 version.

I have a grid in admin panel. Now when I click on this URL it open a form with two tabs in left sidebar. When I click on second tab it show a grid in its right side.

Then I click on a row of this grid it opens a form on another page. In this form there is back button.

How can I change its URL to previous page?

Answer 1

Add your custom back button and remove default one in your Form Container class constructor.

$data = array(
        'label' =>  'Back',
        'onclick'   => 'setLocation(\'' . $this->getUrl('*/*/*') . '\')',
        'class'     =>  'back'
   );
$this->addButton ('my_back', $data, 0, 100,  'header'); 
...
parent::__construct();
...
$this->_removeButton('back');
