Setting nodes children to checked in onclientnodechecking

[KevinMc]

I am trying to set the checked state to true on the children of a tree node when the parent is checked. Following is the treeview and javascript function i tried. Can someone review to make sure the syntax is correct and provide input on whether it whould work?

 <telerik:RadTreeView ID="treeProducts" runat="server" CheckBoxes="true"
 DataFieldID="ProductID" DataFieldParentID="ParentProductID" DataSourceID="odsProducts"
 DataTextField="ProductName" DataValueField="ProductID"
 OnClientNodeChecking="ProductChecking">
</telerik:RadTreeView>

function ProductChecking(sender, eventArgs)
{
     var node = eventArgs.get_node()
     if(node.get_nodes().get_count() > 0)
     {
          for (var i=0; i<node.get_nodes().get_count();i++)
          {
               var childnode = node.get_nodes().getNode(i);
               childnode.set_checked(true);
          }
     }
}

Hi KevinMc,

The syntax seems correct, but I think it will check only the direct child nodes of the node.

I suggest that you check this how-to article:
Checking/Unchecking All Child Nodes
