如何在WPF中将键盘选项卡选择设置为特定控件 [英] how to set keyboard tab selection to a particular control in WPF

问题描述

我有两个文本框和两个按钮......我在第一个文本框Lost Focus事件中写了一些逻辑。一旦我点击键盘标签光标将在第二个文本框闪烁..现在我想选择按钮1或按钮2而不是第二个文本框。我怎么能实现这个...任何想法......建议。



我在第一篇文章末尾添加box LostFocus活动

 Keyboard.Focus（btnName）; 
 
 FocusManager.SetFocusedElement（ this ，btnName）; 

这两个不起作用



提前谢谢

解决方案

set

< Button Name =btnKeyboardNavigation.TabIndex =0/> 

接下来你可以设置哪个控件需要在按下键盘标签键后立即导航

<按钮名称=btn1KeyboardNavigation.TabIndex =1/> ; 

通过在xaml中设置我解决了我的问题

嗨我的朋友。我创建了一个包含控件的小例子。

你是对的。我认为这种行为是因为Control.Property优先。

你必须写入xaml：

 <  网格 >  
 <   TextBox    高度  =  23   宽度  =  80     Horizo​​ntalAlignment   = 左    LostFocus   =  TextBox_LostFocus  /  >  
 <   TextBox    高度  =  23   宽度  =  80    Horizo​​ntalAlignment   = 左   保证金  =  100 80 0 0    KeyboardNavigation.IsTabStop   =  False  /  >  
 <  按钮    x：名称  =  myButton   内容  =  first   高度  =  23   宽度  =  80    VerticalAlignment   = 热门  /  > ;  
 <  按钮   内容  =  second   高度  =  23   宽度  =  80    VerticalAlignment   = 中心  /  < span class =code-keyword>>  
 <   / Grid  >  

和你的代码求得：

  private   void  TextBox_LostFocus（< span class =code-keyword> object  sender，RoutedEventArgs e）
 {
  //  你的逻辑 
 myButton.Focus（）; 
} 

查看这个..

 System.Threading.ThreadPool.QueueUserWorkItem（
（a）= >  
 {
 btnName.Dispatcher.Invoke（
  new 行动（（）= >  
 {
 bnnName.Focus（）; 
 
}））; 
} 
）;

I have two text boxes and two buttons...I had written some logic in first text box Lost Focus event.As soon as i click the keyboard tab cursor will blink at second text box..Now i want to select the button 1 or button 2 instead of second text box.How can i achieve this...any idea...suggestion.

I added at the end of first text box LostFocus event

Keyboard.Focus(btnName);

FocusManager.SetFocusedElement(this, btnName);

these two didn't work

Thanks in advance

解决方案

set

<Button Name="btn" KeyboardNavigation.TabIndex="0"/>

next u can set which control need to navigate as soon as your press keyboard tab key

<Button Name="btn1" KeyboardNavigation.TabIndex="1"/>

by setting in xaml i solved my problem

Hi my friend. i create a small example that contains your controls.
you are right. i think this behavior is because of Control.Property precedeny.
and you must write into xaml:

<Grid>
        <TextBox Height="23" Width="80" HorizontalAlignment="Left" LostFocus="TextBox_LostFocus"/>
        <TextBox Height="23" Width="80" HorizontalAlignment="Left" Margin="100 80 0 0" KeyboardNavigation.IsTabStop="False"/>
        <Button x:Name="myButton" Content="first" Height="23" Width="80" VerticalAlignment="Top"/>
        <Button Content="second" Height="23" Width="80" VerticalAlignment="Center"/>
    </Grid>

and your code begind:

private void TextBox_LostFocus(object sender, RoutedEventArgs e)
      {
          //your logic
          myButton.Focus();
      }

check this one..

System.Threading.ThreadPool.QueueUserWorkItem(
                  (a) =>
                  {
                      btnName.Dispatcher.Invoke(
                      new Action(() =>
                      {
                          btnName.Focus();

                      }));
                  }
                  );
