title: jqGrid custom buttons with edit/delete behaviour
body: <p>I am using custom edit/delete functions in jqGrid and I really enjoyed the fact that they call your custom function after checking if a row was selected or not.</p>
  
  <p>Now I would like to add two more buttons and I would like to use the same behaviour of the edit/delete, so when a row is selected my function get called but if no rows have been selected they show the default popup that says "please select a row first".</p>
  
  <p>Is there a way to achieve this? Alternatively, is there a way to call the method that is called by the grid itself?</p>
  
  <p>thanks!</p>
