change checkboxes values in cascade

[Luis]

Hello,

I'm using a hierarchical radgrid control which has three levels (a master and two detail tables). Each row has a template column that contains a checkbox. What I want to do is to check all checkboxes in the hierarchy when checkbox in the inner row is checked, and I would like to achieve this in client code. 

The only thing I've been able to get is catching the click event on the checkbox and finding the row where the checkbos control is:

     function CkeckBox_Click(e) {      

      if (e.target) {

        gridRow = e.target.parentNode.parentNode;

      }

      else {

        gridRow = e.srcElement.parentNode.parentNode;

      }

Could you please help me?

Thanks in advance.

Hello,

this is the solution I have found. I post it just in case anyone else face the same problem.

  <script type="text/javascript">

    function ToggleSelection(e) {

      var checkbox;

      var gridRow;

      var grid = $find('<%=RadGrid1.ClientID %>');

      var masterTable = grid.get_masterTableView();

      

      checkbox = e.srcElement;

      gridRow = checkbox.parentNode.parentNode;

      IterateGrid(gridRow, masterTable.get_dataItems());

// Some other code     

    }

    function IterateGrid(gridRow, gridItems) {

      var found = false;

      

      for (var n = 0; n < gridItems.length; n++) {

        if (gridItems[n].get_element().id == gridRow.id) {

          found  = true;

        }

        else {          

          for (var i = 0; i < gridItems[n].get_nestedViews().length; i++) {

            found  = RecorreGrid(gridRow, gridItems[n].get_nestedViews()[i].get_dataItems());

            if (found) {

              gridItems[n].get_element().cells[4].childNodes[0].checked = 'checked';

              break;

            }

          }

        }

        if (found)

          break;

      }

      

      return found ;

    }

</script>

My grid has two detail tables and a template column (4-index) that contains an input control of type checkbox.
