title: W2UI grid: Checked Checkboxes not saving;
body: <p>I introduced two buttons on the toolbar one  'CheckAll' and the other 'UncheckAll', they are to have effect on a particular column say 'Status'  (with checkboxes) in the grid. I wrote two Javascript functions to do this.</p>
  
  <pre><code>function check_all(the_unchecked){
          for(i=0; i&lt;the_unchecked.length; i++){
          the_unchecked[i].checked = true;
      }
  }
  
  function uncheck_all(the_checked){
      for(i=0; i&lt;the_checked.length; i++){
          the_checked[i].checked = false;
      }
  </code></pre>
  
  <p>}
   The effected field:</p>
  
  <pre><code>{field: 'status', caption: 'Status', size: '50px', searchable: 'text', resizable: true, render: function (records) {
                      if (records.status === true) {
                          return   '&lt;span style="background-color:#a3e9a4; width:100%;display:block;"&gt; &lt;input class="enable_check" type="checkbox" name="enable_check[]" value="true" checked="true"&gt;&lt;/span&gt;';
                      } else {
                          return  '&lt;span style="background-color:#f69988; width:100%;display:block;"&gt; &lt;input class="enable_check2" name="enable_check[]" value="false" type="checkbox"&gt;&lt;/span&gt;';
                      }
                  }, style: 'text-align:center'},
  </code></pre>
  
  <p>The problem is when I clicked on Save button the checked buttons are nor sent/saved to the database. </p>
  
  <p>What I want is when CheckAll is clicked it checks all checkboxes in the column Status of the fetched rows, then 'Save' persist all the changes to the database. </p>
