方向键导航帮助，请

问题描述

我在网格中有一些按钮，并且想使用箭头键在它们之间导航.我很难让程序在打开时以及在使用TAB使用箭头键开始导航后将注意力集中在按钮上时，我在定向时失去控制 将焦点对准没有按钮的方向.

I have buttons in a grid and would like to navigate between them using arrow keys. I am having a hard time getting the program to focus on a button when it opens and also when after using TAB to start navigation with arrow keys I lose control when directing focus in a direction that does no have a Button. 

我是C#的新手，也是WPF的新手，我正在尝试为HTPC编写一个程序，以使其尽可能对用户友好，因此使用键盘进行的导航将来自游戏或专用.控制器.

I am new to C# and newer to WPF and I am trying to make a program for my HTPC which I am trying to make as user friendly as possible hence the navigation with keyboard which input will be coming from a game and or dedicated controller.

我也获得了Button导航.我想包括一个ListBox以及可能用于不同设置等的更多窗口.

Also after I get the Button nav. I want to include a ListBox and possibly more windows for different settings and such.

在此先感谢您的帮助！

>>我很难让程序在打开时将焦点放在按钮上

>> I am having a hard time getting the program to focus on a button when it opens

要在WPF中设置默认的焦点控件，我们可以使用 FocusManager.FocusedElement xaml中的附加属性:

To set the default focused control in WPF, we can use FocusManager.FocusedElementattached property in xaml:

#FocusManager.FocusedElement附加属性

示例:

<Grid FocusManager.FocusedElement="{Binding ElementName=button1}">
        <Button Name="button1" Width="100" Height="40" Content="Button1" Margin="-150,-50,0,0" Click="button_Click" />
        <Button Name="button2" Width="100" Height="40" Content="Button2" Margin="0,-50,-150,0" Click="button_Click" />
        <Button Name="button3" Width="100" Height="40" Content="Button3" Margin="-150,0,0,-100" Click="button_Click" />
        <Button Name="button4" Width="100" Height="40" Content="Button4" Margin="0,0,-150,-100" Click="button_Click" />
    </Grid>

上面的代码将在程序打开时集中在第一个按钮上.

The above code will focus on the first button when the program opens.

>>并且在使用TAB使用箭头键开始导航之后，将焦点指向没有按钮的方向时，我也失去控制.

>> and also when after using TAB to start navigation with arrow keys I lose control when directing focus in a direction that does no have a Button.
