我想创建具有两列的上下文菜单是这样的：WPF：在上下文菜单项两列
项目的文本约束的项目和快捷方式的名称属性键被绑定到GestureText属性。然而，似乎在列定义不被遵守，我看到：
我的XAML如下：
<Window x:Class="ContextMenu2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid Margin="0,2,0.4,-2.2">
<TextBlock Text="RightClickMe" HorizontalAlignment="Left" VerticalAlignment="Top">
<TextBlock.ContextMenu>
<ContextMenu ItemsSource="{Binding Items}">
<ContextMenu.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*"/>
<ColumnDefinition Width="70*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Name}" />
<TextBlock Grid.Column="1" Text="{Binding GestureText}"/>
</Grid>
</DataTemplate>
</ContextMenu.ItemTemplate>
</ContextMenu>
</TextBlock.ContextMenu>
</TextBlock>
</Grid>
</Window>
C＃
using System;
using System.Collections.ObjectModel;
using System.Globalization;
using System.Windows;
using System.Windows.Input;
namespace ContextMenu2
{
public class CMenu
{
public String Name { get; set; }
public string GestureText { get; set; }
}
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = this;
}
public ObservableCollection<CMenu> Items { get; set; }= new ObservableCollection<CMenu>
{
new CMenu()
{
Name = "Press me",
GestureText =
new KeyGesture(Key.Q, ModifierKeys.Control).GetDisplayStringForCulture(CultureInfo.CurrentUICulture)
},
new CMenu()
{
Name = "Press me too",
GestureText =
new KeyGesture(Key.R, ModifierKeys.Control).GetDisplayStringForCulture(CultureInfo.CurrentUICulture)
}
};
}
}
有什么不对吗？
