我有一个MenuItem,ItemsSource是数据绑定到一个简单的字符串列表,它正确显示,但我很难看到我如何处理他们的点击事件!
这是一个简单的应用程序,演示它:
<Window x:Class="WPFDataBoundMenu.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <Menu> <MenuItem Header="File" Click="MenuItem_Click" /> <MenuItem Header="My Items" ItemsSource="{Binding Path=MyMenuItems}" /> </Menu> </Grid>
using System.Collections.Generic; using System.Windows; namespace WPFDataBoundMenu { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public List<string> MyMenuItems { get; set;} public Window1() { InitializeComponent(); MyMenuItems = new List<string> { "Item 1","Item 2","Item 3" }; DataContext = this; } private void MenuItem_Click(object sender,RoutedEventArgs e) { MessageBox.Show("how do i handle the other clicks?!"); } } }
非常感谢!
克里斯.
解决方法
<MenuItem Header="My Items" ItemsSource="{Binding Path=MyMenuItems}" Click="DataBoundMenuItem_Click" />
代码背后..
private void DataBoundMenuItem_Click(object sender,RoutedEventArgs e) { MenuItem obMenuItem = e.OriginalSource as MenuItem; MessageBox.Show( String.Format("{0} just said Hi!",obMenuItem.Header)); }
事件会冒泡到普通的处理程序.然后,您可以使用头文本或更好的DataContext属性进行切换并根据需要进行操作
