Integrate RadMenu with Sharepoint problem

[Nishim Attreja]

Hello there,

I am trying to create Contextmenu from RadMenu.Net2 version 4.4.5.0.
I am integrating this contextmenu with radtreeview.net2

ContextMenu code is given below in webpart:
relatedDocContextMenu = new RadMenu();
            relatedDocContextMenu.ID = "relDocContextMenu";
            relatedDocContextMenu.IsContext = true;
            relatedDocContextMenu.RadControlsDir = "/_wpresources/RadMenu.Net2/4.4.5.0_bbe59a8ad3533e68/RadControls";

            SPWeb oWeb = null;
            oWeb = SPContext.Current.Web;
            //Adding RadConTextMenu Items
            RadMenuItem itmFavorite = new RadMenuItem("Add Favorite");
            itmFavorite.ImageUrl = oWeb.Url + "/images/favstar.gif";

            relatedDocContextMenu.Items.Add(itmFavorite);

            RadMenuItem itmEmail = new RadMenuItem("Email");
            itmEmail.ImageUrl = oWeb.Url + "/images/favstar.gif";

            relatedDocContextMenu.Items.Add(itmEmail);

            RadMenuItem itmAlert = new RadMenuItem("Set Alert");
            itmAlert.ImageUrl = oWeb.Url + "/images/favstar.gif";

            relatedDocContextMenu.Items.Add(itmAlert);



            relatedDocContextMenu.ContextMenuElementID = "none";
            relatedDocContextMenu.UseEmbeddedScripts = false;


            apnlRelated.Controls.Add(relatedDocContextMenu);
====
apnlRelated is RadAjaxPanel in whic tree is also there.
=======================

Code to add contextmenu in treeview:
tvRelated = new RadTreeView();
            tvRelated.ID = "tvRelated";
            tvRelated.BeforeClientClick = "BeforeClientClickHandler";
            tvRelated.BeforeClientContextMenu = "ShowRadMenu";
            tvRelated.RadControlsDir = "/_wpresources/RadControls/";
            //tvRelated.ShowLineImages = false;
            //tvRelated.ImagesBaseDir = "/_wpresources/RadControls/Treeview/Skins";
            tvRelated.Skin = "Color";
            tvRelated.NodeBound += new RadTreeView.RadTreeViewEventHandler(tvRelated_NodeBound);
==========
script for ShowRadMenu:
===
private const string relatedDocConTextMenuScriptKey = "RelatedDocConextMenu";
        private string relatedRadContextMenuScript = "<script language='javascript' type='text/javascript'>";

            relatedRadContextMenuScript += "function ShowRadMenu(node, e)";
            relatedRadContextMenuScript += "{    ";
            relatedRadContextMenuScript += " var menu = null; ";
            //relatedRadContextMenuScript += "if (node.Category == 'Folder')";
            //relatedRadContextMenuScript += "{";
            //relatedRadContextMenuScript += "   menu = window['<%= relatedDocContextMenu.ClientID %>'];";window['ctl00_m_g_197245f5_94be_4c1a_8fb1_8a924e6e7f33_relDocContextMenu'];
            //relatedRadContextMenuScript += "}";
            //relatedRadContextMenuScript += "else";
            //relatedRadContextMenuScript += "{";
            relatedRadContextMenuScript += " alert(window['<%= relDocContextMenu.ClientID %>']);  menu = window['<%= relDocContextMenu.ClientID %>']; ";
            //relatedRadContextMenuScript += "}";
            relatedRadContextMenuScript += "  if (menu)";
            relatedRadContextMenuScript += "{";
            relatedRadContextMenuScript += "   menu.Show(e);";
            relatedRadContextMenuScript += "   e.cancelBubble = true;";
            relatedRadContextMenuScript += "   if (e.stopPropagation)";
            relatedRadContextMenuScript += "  {";
            relatedRadContextMenuScript += "e.stopPropagation();";
            relatedRadContextMenuScript += "   }";
            relatedRadContextMenuScript += " e.returnValue = false;";
            relatedRadContextMenuScript += "if (e.preventDefault)";
            relatedRadContextMenuScript += " {";
            relatedRadContextMenuScript += "    e.preventDefault();";
            relatedRadContextMenuScript += "}";
            relatedRadContextMenuScript += "}";
            relatedRadContextMenuScript += "}";
            relatedRadContextMenuScript += "</script>";
================
My problem is when i am right click on treenode this conextmenu should show. Is is calling the ShowRadMenu  funtion but it is not detecting RadMenu object.
alert(window['<%= relDocContextMenu.ClientID %>']);
The Above alert is showing "undefined";

SafeControls Entries:
<SafeControl Assembly="RadMenu.Net2, Version=4.4.5.0, Culture=neutral, PublicKeyToken=bbe59a8ad3533e68" Namespace="Telerik.WebControls" TypeName="*" Safe="True" />

<SafeControl Assembly="RadMenu.Net2, Version=4.4.5.0, Culture=neutral, PublicKeyToken=bbe59a8ad3533e68" Namespace="Telerik.RadMenuUtils" TypeName="*" Safe="True" />

I also tried with var menu = <%= relDocContextMenu.ClientID %>;
but no luck.
I also unchecked in configuration .axd - with "verify that file Exists".

Please help me out in this.

Thanks and Regards,

Hello Nishim Attreja,

You should use the following code to get the menu client-side object:

relatedRadContextMenuScript += "var menu = window['" + relatedDocContextMenu.ClientID +"']";

['<%= relatedDocContextMenu.ClientID %>'] cannot be used from codebehind because it is a server-side expression evaluated when the ASP.NET runtime parses the ASPX file for the first time.
