WPF的菜单类控件

Menu菜单

 1         <Menu Grid.Row="1" >
 2             <MenuItem Header="通讯录1 >">
 3                 <MenuItem.Items>
 4                     <MenuItem Header="张三">
 5                         <MenuItem.Icon >
 6                             <Image Source="../Resources/111.ico"/>
 7                         </MenuItem.Icon></MenuItem>
 8                     <MenuItem Header="李四"/>
 9                     <MenuItem Header="王五"/>
10                 </MenuItem.Items>
11             </MenuItem>
12             <MenuItem Header="通讯录2 >">
13                 <MenuItem.Items>
14                     <MenuItem Header="张三"/>
15                     <MenuItem Header="李四"/>
16                     <MenuItem Header="王五"/>
17                 </MenuItem.Items>
18             </MenuItem>
19         </Menu>
Menu

层级绑定方式：

1         <Menu ItemsSource="{Binding MenuList}">
2             <Menu.ItemTemplate>
3                 <HierarchicalDataTemplate ItemsSource="{Binding Childs}">
4                     <TextBlock Text="{Binding Name}"/>
5                 </HierarchicalDataTemplate>
6             </Menu.ItemTemplate>
7         </Menu>

VM中属性：

 1         private ObservableCollection<MenuNode> menulist;
 2         public ObservableCollection<MenuNode> MenuList
 3         {
 4             get { return menulist; }
 5             set
 6             {
 7                 menulist = value;
 8                 RaisePropertyChanged();
 9             }
10         }
11 
12         public class MenuNode
13         {
14             public string Name { get; set; }
15             private List<MenuNode> childs = new List<MenuNode>();
16             public List<MenuNode> Childs
17             {
18                 get { return childs; }
19             }
20         }
ViewModel

右键菜单

 1     <Button Content="右键菜单"  MouseRightButtonDown="Button_MouseRightButtonDown" >
 2     private void Button_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
 3         {
 4             (sender as Button).ContextMenu = CreateMenu();
 5             (sender as Button).ContextMenu.IsOpen = true;
 6         }
 7  
 8         private ContextMenu CreateMenu()
 9         {
10             ContextMenu menu = new ContextMenu();
11             for (int i = 0; i < 4; i++)
12             {
13                 menu.Items.Add(new MenuItem() { Header = "1" + i });
14             }
15             return menu;
16         }
cs实现

树形菜单

1         <TreeView ItemsSource="{Binding MenuList}">
2             <TreeView.ItemTemplate>
3                 <HierarchicalDataTemplate ItemsSource="{Binding Childs}" >
4                     <TextBlock Text="{Binding Name}"/>
5                 </HierarchicalDataTemplate>
6             </TreeView.ItemTemplate>
7         </TreeView>

下拉菜单

1         <ComboBox SelectedIndex="2">    
2             <ComboBox.Items>
3                 <ComboBoxItem Content="菜单1"/>
4                 <ComboBoxItem Content="菜单2"/>
5                 <ComboBoxItem Content="菜单3"/>
6                 <ComboBoxItem Content="菜单4"/>
7             </ComboBox.Items>
8         </ComboBox>

也可以用Popup实现菜单效果；
