将命令绑定到输入手势 [英] Binding a Command to an Input Gesture

问题描述

你好，
我将InputGesture绑定到命令，这部分起作用.
看起来如下:

背后的代码:

Hello,
i bound a InputGesture to a Command, which partly works.
looks as Follows:

Code Behind:

public static RoutedCommand myCommand = new RoutedCommand();
private void MyCommandExecuted(object sender, ExecutedEventArgs e)
{
    MessageBox.Show("Test");
}

<UserControl.CommandBindings>
<CommandBinding Command="var:UserControlName.myCommand" Executed="MyCommandExecuted">
</Usercontrol.CommandBindings>

<USerControl.InputBindings>
<KeyBinding Command="var:UserControlName.myCommand" Key="A">
</USerControl.InputBindings>

此命令也已分配给用户控件中的按钮.如果我运行我的项目，请在键盘上按"A"，则不会发生任何事情.如果我按下按钮，将显示消息框.一次按下按钮后，键盘键也起作用.如果我现在再次按"A"，则也会出现messageBox.

为什么我必须先按一次Butten，然后才能使用"A"?我做错了什么?

寻求帮助

问候Moti

This command is also assigned to a button in the user Control. if i run my project, an press "A" on the Keyboard, nothing Happens. if i Press the Button, the Message Box appears. After once pressing the Button, also the Keyboard Key works. if i now press "A" again, the messageBox appears too.

Why do i i have to press the Butten once first, before i can use "A"?? What am i doing wrong?

thx for help

kind regards Moti
