How to hide a context menu option

[Hemangajit Dutta]

Hi,
       I am using a tree view where the nodes are using a context menu with two options "Delete"and "View". Depening on certain condition I need to remove the "Delete" menu option from some of the nodes. Could you please let me know how to achieve that?

Thanks

Hi Hemangajit,

I suggest you subscribe to OnClientContextMenuShowing event of the treeview and show/hide the "Delete" item in its handler:

<script type="text/javascript">
    function contextMenuShowing(sender, args) {
        if (//condition)
            args.get_menu().findItemByText("Delete").set_visible(false);
        else
            args.get_menu().findItemByText("Delete").set_visible(true);
    }
</script>
