    How can I add a confirmation dialog to the context menu for the delete menu item? I have tried the 'OnClientItemClicking' property (see below), but get runtime error: 'OnClientItemClicking' property cannot be set declaratively.



    <script type="text/javascript">

     function onClicking(sender, eventArgs)
        var item = eventArgs.get_item();
        var proceed = confirm("Permanently delete this Date and ALL samples under it?");

        if (!proceed)


    <telerik:RadTreeViewContextMenu runat="server" ID="ChemicalDateMenu" ClickToOpen="True" Skin="Vista" OnClientItemClicking="onClicking">
      <telerik:RadMenuItem Text="Add New Sample" Value="ChemicalAdd" runat="server"></telerik:RadMenuItem>
      <telerik:RadMenuItem Text="Delete Sample" Value="ChemicalDelete" runat="server"></telerik:RadMenuItem>
     <CollapseAnimation Duration="200" Type="OutQuint" />

    Thx Marcel

    Hi Macrel,

    You're using context menu of the RadTreeView, so you should subscribe to OnClientContextMenuItemClicking event of the treeview. You can find the clicked item in its handler like this:

    function onClicking(sender, eventArgs)
    var item = eventArgs.get_menuItem();
    . . .

    Hope this helps.

    Best wishes,
