I created a module using the module creator. I am trying to overwrite Adminhtml\Block\Sales\Order\Grid.php <pre><code>class Mage_Adminhtml_Block_Sales_Order_Grid extends Mage_Adminhtml_Block_Widget_Grid </code></pre> and my overwritten block is in local\Delivery\Date\Block\Sales\Order\Grid.php <pre><code>class Delivery_Date_Block_Sales_Order_Grid extends Mage_Adminhtml_Block_Sales_Order_Grid </code></pre> and the function to overwrite is <pre><code>protected function _prepareColumns() { </code></pre> I face a strange problem when I try to overwrite a function in my module Block the change are not affected instead if I comment out the same function lines in the Mage folder my function is overwritten. Suppose i have a function in local\Delivery\Date\Block\Sales\Order\Grid.php as <pre><code>protected function _prepareColumns() { $this->addColumn('real_order_id', array( 'header'=> Mage::helper('sales')->__('Order NEW ID#'), 'width' => '80px', 'type' => 'text', 'index' => 'increment_id', ));} </code></pre> noting happens instead if I comment/delete the line in Adminhtml\Block\Sales\Order\Grid.php <pre><code>protected function _prepareColumns() { $this->addColumn('real_order_id', array( 'header'=> Mage::helper('sales')->__('Order #'), 'width' => '80px', 'type' => 'text', 'index' => 'increment_id', )); </code></pre> Then only my changes are affected in the adminhtml grid. Why is the fallback changes happening ? config.xml <pre><code><blocks> <adminhtml> <rewrite> <sales_order_grid>Delivery_Date_Block_Sales_Order_Grid</sales_order_grid> </rewrite> </adminhtml> </blocks> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
