Treeview clientside select unselect nodes with checkbox

[vairam]

Hi

I am using Telerik tree view control with checkboxs.
What i need is when i select the parent node it should select all the child's nodes like wise unselect also.
I am using this javascript code

function UpdateAllChildren(nodes, checked)
{
   var i;

       for (i=0; i<nodes.get_count(); i++)
       {
           if (checked)
           {
               nodes.getNode(i).check();
           }
           else
           {
               nodes.getNode(i).set_checked(false);
           }
           
           if (nodes.getNode(i).get_nodes().get_count()> 0)
           {
               UpdateAllChildren(nodes.getNode(i).get_nodes(), checked);
           }
       }
       if ((nodes.get_count()==0) && (nodes._parent._parent._parent!=null) && (!checked))
       {
        nodes._parent._parent.set_checked(false);
       }
}
if the selected node has more than 200 child Nodes (nodes.get_count() > 200) then i am always getting this error

I think there already is such a functionality in the TreeView. As seen in the CheckBox Support demo there is a property called "CheckChildNodes" which you should set to true!
