Hello Sir,

I followed the sample fo TreeView with ContextMenu but it can not pupup any menu. Please help to solve the problem. Thank you.

The code I tested is:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TreeViewDemo.aspx.cs" Inherits="KosmasWebTest.Demos.TreeViewDemo" %>
<%@ Register Src="../Control/ItemTree.ascx" TagName="ItemTree" TagPrefix="uc1" %>
<%@ Register Assembly="EO.Web" Namespace="EO.Web" TagPrefix="eo" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>

<body>
<script type="text/javascript">

function ShowContextMenu(e, treeView, node)
{
//Get the context menu object
var menu = eo_GetObject("<%=Menu1.ClientID%>");

//Modify the context menu
menu.getTopGroup().getItemByIndex(0).setText("Open '" + node.getText() + "'");
menu.getTopGroup().getItemByIndex(1).setText("Delete '" + node.getText() + "'");

//Display the context menu. See documentation
//for the Menu control for details about how
//to handle menu item click event
eo_ShowContextMenu(e, "<%=Menu1.ClientID%>");

//Returns true to indicate that we have
//displayed a context menu
return true;
}
