I created my custom grid in an extension but I don't know if it is something with permission or not that a button is not showing up in grid customization: enter image description here

it should have add attribute column like this: enter image description here


class Lenmar_Lightbulbs_Adminhtml_LightbulbsController extends Mage_Adminhtml_Controller_action
protected function _isAllowed()
        return Mage::getSingleton('admin/session')->isAllowed('lightbulbs/lightbulbs');

public function indexAction() {



public function gridAction()



my cache is disabed and I reindexed it didn't help even I copy pasted my other extension which has this button and again rename everything it didn't work

I have the buttons comming from T:\app\code\community\BL\CustomGrid\Block\Widget\Grid\Columns\Config.php

here is the function:

public function getAddColumnButtonHtml()
    return parent::getButtonHtml($this->__('Add Attribute Column'), $this->getJsObjectName().'.addColumn();', 'scalable add');

also I can rename other ones and they will be changed in button text

also I found the condition! that when to show it:

   <?php if ($this->canDisplayColumnsConfig()): ?>
                                <?php if ($_gridModel->canHaveAttributeColumns()): ?>
                                    <span class="field-row">
                                        <?php echo $this->getAddColumnButtonHtml() ?>
                                <?php endif ?>

I commented out this if condition and add attribute column showed up but I cannot do it it would affect other areas where add column shouldn't be there it seems I have some permission problem which I dont know how to figure out for this extension

  • Flush cache and reindex data then relogin once this may help. – dh47 Nov 14 '14 at 1:58
  • Please add some code on how you implemented this. – Anna Völkl Nov 14 '14 at 6:48
  • my cache is disabled – Nickool Nov 14 '14 at 15:43
  • Anna which part of extention you like to see? controller?grid? what? – Nickool Nov 14 '14 at 15:44
  • If you make a random change to artificial properties is this reflected in your admin (lets say.. renaming one of the other buttons)? – hownowbrowncow Nov 14 '14 at 18:59

I figured it out: I should add the type of grid and then it will be addable


public function isAppliableToGrid($type, $rewritingClassName)
return $type == 'lightbulbs/adminhtml_lightbulbs_grid';



public function isAppliableToGrid($type, $rewritingClassName){

    return (($type == 'adminhtml/catalog_product_grid')
        || ($type == 'adminhtml/catalog_category_tab_product')
        || ($type == 'adminhtml/catalog_product_edit_tab_related')
        || ($type == 'adminhtml/catalog_product_edit_tab_upsell')
        || ($type == 'adminhtml/catalog_product_edit_tab_crosssell')
        || ($type == 'lightbulbs/adminhtml_lightbulbs_grid'));
