title: Find Duplicate Values in the Gridview using Javascript
body: <p>I have a following requirement. I have a Gridview contains two columns:</p>
  <div class="s-table-container">
  <table class="s-table">
  <thead>
  <tr>
  <th>Model Name</th>
  <th>Model Description</th>
  <th></th>
  </tr>
  </thead>
  <tbody>
  <tr>
  <td>Model A</td>
  <td>Model A Desc</td>
  <td><kbd>Edit</kbd> <kbd>Update</kbd> <kbd>Cancel</kbd></td>
  </tr>
  <tr>
  <td>Model B</td>
  <td>Model B Desc</td>
  <td><kbd>Edit</kbd> <kbd>Update</kbd> <kbd>Cancel</kbd></td>
  </tr>
  <tr>
  <td>Model C</td>
  <td>Model C Desc</td>
  <td><kbd>Edit</kbd> <kbd>Update</kbd> <kbd>Cancel</kbd></td>
  </tr>
  </tbody>
  </table>
  </div>
  <p>Let's when user click <kbd>Edit</kbd> link on model C then when he type Model B (Replace 'Model C' with 'Model B') then on <kbd>Update</kbd> link I would like to warn the user that Model B already been defined. I would appreciate your help. For your information both <code>txtModelName</code> and <code>txtModelDesc</code> are template fields.</p>
