view check box just in leaf

[Mojtaba]

Is there any way to view rad tree nodes just in leaves?
I wrote this code but all nodes was checkbox.

<telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True"/>

Hello,

I tried following client side code in order to achieve required scenario. Give a try with this:

ASPX:

<telerik:RadTreeView ID="RadTreeView1" OnClientLoad="OnClientLoad" runat="server" CheckBoxes="True" CheckChildNodes="True">
  . . .
</telerik:RadTreeView>

JavaScript:

<script type="text/javascript">
function OnClientLoad(sender, args)
{
    var allNodes = sender.get_allNodes();
    for(var i =0; i< sender.get_allNodes().length ; i ++)
    {
        if(allNodes[i].get_nodes().get_count() != 0)
        {
            allNodes[i].get_checkBoxElement().style.display = "none";
        }
    }
}
</script>

Thanks,
Princy.

I have same problem but your script doesn't solve it.
I guess this is because my treeview is ondemand.

<script type="text/javascript">
function TreeOnClientLoad(sender, args) {
        var allNodes = sender.get_allNodes();
        debugger;
        for (var i = 0; i < sender.get_allNodes().length; i++) {
            if (allNodes[i].get_nodes().get_count() != 0) {
                allNodes[i].get_checkBoxElement().style.display = "none";
            }
        }
    }
</script>

<telerik:RadTreeView runat="server" ID="rtvClasses" OnClientLoad='TreeOnClientLoad'
                        dir="rtl">
                    </telerik:RadTreeView>

and the code behind is:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            rtvClasses.Nodes.Clear();
            RadTreeNode node = new RadTreeNode();
            node.Text = TreeFirstElementName;
            node.Value = "0";
            node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;
            rtvClasses.Nodes.Add(node);
            rtvClasses.CheckBoxes = TreeCheckable;
            rtvClasses.CheckChildNodes = TreeCheckable;
        }
    }
void rtvClasses_NodeExpand(object sender, RadTreeNodeEventArgs e)
    {
        ClassManagerClient service = new ClassManagerClient();
        RadTreeNodeData[] list = service.GetClassesByParentIdAndType(Convert.ToInt64(e.Node.Value), ClassType.Project);
        service.Close();
        e.Node.Nodes.Clear();
        e.Node.Nodes.AddRange(PublicFunctions.GetRadTreeNodes(list.ToList()));
        e.Node.Expanded = true;
    }

Thanks in advance
