前面一篇文章已经写了自己构建右键菜单的方法，本章主要来探讨一下，使用微软Menu 类来构建右键菜单的方法，这些用法笔者在自己的系统中都有所采用。
第二种实现方法，就是用微软的Menu类来构建 ，并且在相应的地方实例化该菜单，把它弹出来。
Ⅰ菜单类
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using TDWS.Client.UI.Query;
using Chaos.Controls.Windows;
using TDWS.Client.UI.Edit;
using System.Collections.Generic;
using SuperMap.Web.Core;
namespace TDWS.Client.UI.SuperMapUI
{
public class ReservoirRightMenu
{
public ContextMenu menu = new ContextMenu();
public ReservoirRightMenu()
{
MenuItem ReservoirInfo = new MenuItem();
ReservoirInfo.Header = "人口基本信息";
ReservoirInfo.Click += new RoutedEventHandler(ReservoirInfo_Click);
menu.Items.Add(ReservoirInfo);
}
public ContextMenu ContextMenu()
{
MenuItem ReservoirInfo = new MenuItem();
ReservoirInfo.Header = "人口基本信息";
ReservoirInfo.Click += new RoutedEventHandler(ReservoirInfo_Click);
menu.Items.Add(ReservoirInfo);
return menu;
}
//人口基本信息
void ReservoirInfo_Click(object sender,RoutedEventArgs e)
{
//实例化一个人口基本信息对话框。
ReservoirBaseinformationUI reservoirInfo = new ReservoirBaseinformationUI();
//弹出对话框
WindosEx.ShowDialog("人口基本信息",700,600,reservoirInfo);
}
}
}
Ⅱ菜单的实例化，弹出
/// <summary>
///行政区右键菜单¹
/// </summary>
/// <param name="sender"></param>
void featureRiver_MouseRightButtonDown(object sender,MouseButtonEventArgs e)
{
e.Handled = true;
}
/// <summary>
///行政区右键菜单¹¹
/// </summary>
/// <param name="sender"></param>
void featureRiver_MouseRightButtonUp(object sender,MouseButtonEventArgs e)
{
RiverRightMenu riverContextMenu = new RiverRightMenu();
ContextMenu menu = riverContextMenu..Menu;
menu.VerticalOffset = e.GetPosition(this).Y;
menu.HorizontalOffset = e.GetPosition(this).X;
menu.IsOpen = true;
}
