    Hi,

    I create a TreeView  with this code:

     

     

    <

     

    telerik:RadTreeView ID="rtvLineeBeni" Runat="server" OnNodeExpand="RTV_NodeExpand"

     

    Font-Names="Arial" Font-Size="12pt" Font-Strikeout="False" Skin="WebBlue"

     

    BorderColor="Gray" Height="390px" Width="748px" AllowNodeEditing="true"

     

    OnClientContextMenuItemClicking="onClientContextMenuItemClicking"

     

    onnodeedit="rtvLineeBeni_NodeEdit" >
    <Nodes>  

     

     

     

     

     

    <telerik:RadTreeNode Value="1" ImageUrl="~/Images/ImagesTree/Reparto.png"

     

    AllowEdit="false" Text="Reparto" Expanded="true" ContextMenuID="MainContextMenuInsert" >  

     

     

     

     

    </telerik:RadTreeNode>

     

    </Nodes>

     

    </telerik:RadTreeView>

     

    Then i populate it ON DEMAND(c# code)

    How can i get the selected node with javascript ?
    I try this:

     

     

     

     

    var oId = document.getElementById('<%=rtvLineeBeni.ClientID %>').value

    var oId = document.getElementById('<%=rtvLineeBeni.ClientID %>_SelectedNode').value

    but it tells me that it's Undefined ...

    Thanks !

    Hello,

    You need to use $find() method to get the client object of ajax enabled controls.
                 var tree = $find("<%= RadTreeView1.ClientID %>");


    Now use the get_selectedNode() method to get the selected node. The documentation shows most important client side methods of RadTreeview.
