thats the code from my grid.php

<?php

      class Ecom_Pricenotify_Block_Adminhtml_Pricenotify_Grid extends Mage_Adminhtml_Block_Widget_Grid{
public function __construct()
{
    parent::__construct();
    $this->setId('pricenotifyGrid');
    // This is the primary key of the database
    $this->setDefaultSort('pricenotify_id');
    $this->setDefaultDir('ASC');
    $this->setSaveParametersInSession(true);
}

protected function _prepareCollection()
{
    $collection = Mage::getModel('pricenotify/pricenotify')->getCollection();
    $this->setCollection($collection);
    return parent::_prepareCollection();
}

protected function _prepareColumns()
{
    $this->addColumn('pricenotify_id', array(
        'header'    => Mage::helper('pricenotify')->__('Notification ID'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'pricenotify_id',
    ));

    $this->addColumn('prod_id', array(
        'header'    => Mage::helper('pricenotify')->__('Product ID'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'prod_id',
    ));


    $this->addColumn('prod_price', array(
        'header'    => Mage::helper('pricenotify')->__('Product Price'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'prod_price',
    ));

    $this->addColumn('user_price', array(
        'header'    => Mage::helper('pricenotify')->__('User Price'),
        'align'     =>'left',
        'width'     => '50px',
        'index'     => 'user_price',
    ));

    $this->addColumn('email', array(
        'header'    => Mage::helper('pricenotify')->__('E-Mail Address'),
        'align'     =>'left',
        'width'     => '150px',
        'index'     => 'email',
    ));

    $this->addColumn('created_time', array(
        'header'    => Mage::helper('pricenotify')->__('Creation Time'),
        'align'     => 'left',
        'width'     => '120px',
        'type'      => 'date',
        'default'   => '--',
        'index'     => 'created_time',
    ));


    $this->addColumn('status', array(

        'header'    => Mage::helper('pricenotify')->__('Status'),
        'align'     => 'left',
        'width'     => '80px',
        'index'     => 'status',
        'type'      => 'options',
        'options'   => array(
            'success' => 'Inactive',
            'pending' => 'Active',
        ),
    ));

   return parent::_prepareColumns();
}

public function getRowUrl($row)
{
   return $this->getUrl('*/*/edit', array('id' => $row->getId()));
}}

and this indexAction function is from the controller

  public function indexAction() {
    $this->_initAction();       
    $this->_addContent($this->getLayout()->createBlock('pricenotify/adminhtml_pricenotify'));
    $this->renderLayout();
  }

Discover grid container or update your question with grid container and layout.xml. – Dovap

Answer 1

Maybe you're inserting it in the layout, check pricenotify.xml in

adminhtml>default>default>layout.

Such as:

  <pricenotify_adminhtml_manager_pricenotify>
        <block type="core/text_list" name="root" output="toHtml">
            <block type="pricenotify/adminhtml_pricenotify_grid" name="pricenotify.grid"/>
        </block>
  </pricenotify_adminhtml_manager_pricenotify>

Remove this block or comment the line where you add the content.

Answer 2

I fixed it. i only had to comment out

//$this->_addContent($this->getLayout()->createBlock('pricenotify/adminhtml_pricenotify'));

from indexAction i guess iwas loading it twice.

Answer 3

make sure that the grid block isn't already loaded in the corresponding layout.xml file.

Answer 4

Well I was facing the same issue but in my case it was due to $this->setId('messages'); line (in your Grid.php construct). Because magento already has same <div id="messages"></div> in its grid page(for showing notifications) due to which my grid content was getting loaded within this 'div' tag hence showing grid twice. So lesson learned is don't give general name while setting your 'id' in Grid.php which could already be present in the grid page.

Answer 5

In my case, it's happened on Edit/Form, and I had duplicated unintentionally renderLayout() on my Adminhtml controller.

$this->renderLayout();
