title: magento product grid pagination and searching in edit page tab in custom module
body: <p>Can anyone help me?</p>
  
  <p>I have created custom module that uses product detail. I have used product grid in add/edit page to select product and it is working fine but the problem is "product grid pagination and searching is not working" it forwards me to client side when ever I click on pagination and search button on product grid.</p>
  
  <p>To create product grid in add page tab, I have created one block page with <code>Mage_Adminhtml_Block_Widget_Grid</code> and override all grid method. Actually I have paste <code>core/Mage/adminhtml/block/catelog/product/grid.php</code> code in my file.</p>
  
  <p>I know the problem that <code>getGridUrl()</code> method does not finding the productcontroller url, thats why the pagination and sorting is not working. </p>
  
  <p>I want product grid with custom column so I cant reuse main product grid. I must have to create my own product grid.</p>
