title: jquery, jqgrid validation before add or Edit using pager
body: <ol>
  <li>I am successfully using Jqgrid with MVC .net 4.0, with pager showing Add-Edit-Delete buttons.
  On click on Add-Edit button the dialog box pops up and on click of submit button on the dialog box, 2. I am successfully updating data at server.</li>
  <li>On of the columns is using drop down list ( edittype: "select")</li>
  </ol>
  
  <p>Now, 
  a. I want to validate some data on click of the Submit button.
  b. I want to send "Id" instead of "text", of the "select" type column to the server, on submit click.</p>
  
  <p>Thanks</p>
