快照 [ ^ ]



到目前为止，我已完成以下工作：



//我的命令



I am trying to bind an InputGesture to a RoutedCommand bound to a MenuItem inside a ContextMenu.

As shown below, I am trying to bind a KeyGesture to "Language->English/England" MenuItem where "Language" is a Button and "English/England" is a MenuItem inside the ContextMenu of "Language" button.

So far, I have done following:

// my command

public static RoutedCommand SetCultureENCommand = new RoutedCommand ("SetCultureENCommand", typeof(ContextMenu));

在XAML模板中，我有以下内容，

in XAML template, I have following,

<Button x:Name="btnCulture" Grid.Column="2" Grid.Row="0">
	<Button.Style>
		<Style.Triggers>
			<EventTrigger RoutedEvent="Click">
				<EventTrigger.Actions>
					<BeginStoryboard>
						<Storyboard>
							<BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="ContextMenu.IsOpen">
								<DiscreteBooleanKeyFrame KeyTime="0:0:0" Value="True" ></DiscreteBooleanKeyFrame>
                                                        </BooleanAnimationUsingKeyFrames>
						</Storyboard>
					</BeginStoryboard>
				</EventTrigger.Actions>
			</EventTrigger>
		</Style.Triggers>
		<Setter Property="ContextMenu">
			<Setter.Value>
				<ContextMenu>
					<MenuItem Header="German/Germany" Command="{x:Static DesignerItems:DesignerCanvas.SetCultureDECommand}" Style="{StaticResource MenuItemStyle}">
						<MenuItem.Icon>
							<Image Source="/myImageDir/de.png" Width="20"></Image>
						</MenuItem.Icon>
					</MenuItem>
					<MenuItem Header="English/England" Command="{x:Static DesignerItems:DesignerCanvas.SetCultureENCommand}" Style="{StaticResource MenuItemStyle}">
						<MenuItem.Icon>
							<Image Source="/myImageDir/gb.png" Width="20"></Image>
						</MenuItem.Icon>
					</MenuItem>
				</ContextMenu>
			</Setter.Value>
		</Setter>		
	</Button.Style>
</Button>

我将输入手势添加到此命令中：

I am adding the input gesture to this command as:

DesignerCanvas.SetCultureENCommand.InputGestures.Add(new KeyGesture(Key.F11, ModifierKeys.None));

最后，我将其注册为：

and finally, I am registering this as:

CommandManager.RegisterClassCommandBinding(typeof(ContextMenu), new CommandBinding(DesignerCanvas.SetCultureENCommand, SetCultureToEN));



我试过得到它像这个问题 [ ^ ]，但似乎 KeyGesture 仅 / b> 当我明确点击语言然后按下手势（即明确打开<后） code>文本菜单）。当我通过 MainWindow 本身按下手势时（即没有明确地打开 ContextMenu ），它无法正常工作。 />


任何帮助都会非常感激。在此先感谢。

I tried to get it done something like this SO question[^], but it seems the KeyGesture is only working when I explicitely click the "Language" first and then press the gesture (i.e. after explicitely opening the ContextMenu). It is not working when I press the gesture through the MainWindow itself (i.e. without explicitely opening the ContextMenu).

Any help would be really appreciated. Thanks in advance.
