创建单个按键绑定，该按键绑定会在每次按下具有任何数字的控件时触发命令，然后将该数字作为参数传递? [英] Create a single key-binding that fires a command every time control is pressed with any number and then passes the number as a parameter?

问题描述

我需要为每个控件+数字组合创建热键，并且希望不创建十个命令.有什么办法吗?

I need to create hot-keys for every control + number combination and would prefer not to have create ten commands. Is there any way to do this?

推荐答案

如果我理解您的问题，那么您只有一个命令，例如MyCommand，如果用户按下CTRL + 0到CTRL +，则要触发它9，并为每个组合指定不同的参数.

If I understand your question, you have a single command, say MyCommand, and you want to fire it if the user presses CTRL+0 through CTRL+9, and give the command a different parameter for each combination.

在这种情况下，只需在窗口中创建10个键绑定，所有键绑定都已绑定到MyCommand，并为它们提供一个参数:

In that case, just create 10 key bindings in your window, all bound to MyCommand, and give them a parameter:

<Window.InputBindings>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+0" CommandParameter="0"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+1" CommandParameter="1"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+2" CommandParameter="2"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+3" CommandParameter="3"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+4" CommandParameter="4"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+5" CommandParameter="5"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+6" CommandParameter="6"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+7" CommandParameter="7"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+8" CommandParameter="8"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+9" CommandParameter="9"/>
</Window.InputBindings>
