title: jqGrid - how to find iRow (index of the row) from rowId (table pri key)
body: <p>I have rows from a table in jqGrid. I manipulate the behaviour of <code>cellEdit</code> and now use it for editing. After I init the grid, I will use;</p>
  
  <pre><code>$('#grid').editCell(iRow,1,false);
  </code></pre>
  
  <p>to just select the cell.</p>
  
  <p>but I have only <code>rowId</code> not <code>iRow</code>. How can I get <code>iRow</code> from <code>rowId</code>?</p>
