C＃WPF取消选中复选框 [英] C# WPF uncheck checkboxes

问题描述

我使用微软的Visual 2013 Express中，C＃和WPF。

在我的计划有六个复选框，当其中一人被选中，其他五宜得到选中。

我GOOGLE的最后两个小时，但无法找到一个解决方案，在C＃初学者。在Java中，我将只写 checkbox1.setSelected（假）;

我添加了一个clickevent，一检查，选中EVET在C＃代码。我加了经过和未选中中的.xaml，但我不知道烫得到它的工作。

希望你能帮助我：）

============== =========

我的解决办法：

感谢您的帮助。我尝试了一些随机的东西与器isChecked你的建议，并得到它的工作，很幸运

.XAML如下：

 <复选框X：NAME =CheckBox1...经过=CheckBox1_Checked/> 
<复选框X：NAME =CheckBox2...经过=CheckBox2_Checked/> 
<复选框X：NAME =CheckBox3...经过=CheckBox3_Checked/> 
<复选框X：NAME =CheckBox4...经过=CheckBox4_Checked/> 
<复选框X：NAME =CheckBox5...经过=CheckBox5_Checked/> 
<复选框X：NAME =CheckBox6...经过=CheckBox6_Checked/>为CheckBox1 
  

C＃代码：

 私人无效CheckBox1_Checked（对象发件人，RoutedEventArgs E）
 {
 CheckBox1.IsChecked = TRUE; 
 CheckBox2.IsChecked = FALSE; 
 CheckBox3.IsChecked = FALSE; 
 CheckBox4.IsChecked = FALSE; 
 CheckBox5.IsChecked = FALSE; 
 CheckBox6.IsChecked = FALSE; 
} 
  

例如。为CheckBox2：

 私人无效CheckBox2_Checked（对象发件人，RoutedEventArgs E）
 {
 CheckBox2.IsChecked =真正; 
 CheckBox1.IsChecked = FALSE; 
 CheckBox3.IsChecked = FALSE; 
 CheckBox4.IsChecked = FALSE; 
 CheckBox5.IsChecked = FALSE; 
 CheckBox6.IsChecked = FALSE; 
} 
  

那么，到底，这是一个很容易的任务来完成。

解决方案

  checkbox1.IsChecked = FALSE; 
  

的 ToggleButton.IsChecked物业

我读它为一个特殊的。如果你想有一次只有一个选择了，那么单选按钮会那样做。结果
默认情况下你不能说取消选中其他5结果
取消选中一个单选按钮。结果
这将使所有6选中。

我想结合较好，实现INotifyPropertyChanged

 私人布尔cbSecial = FALSE; 
私人布尔CB1 = FALSE; 
私人布尔CB2 = FALSE; 
公布尔CbSpecial 
 {
 {返回cbSecial; } 
组
 {
如果（价值== cbSecial）回报; 
 cbSecial =价值; 
如果（cbSpecial）
 {
 Cb1的= FALSE; 
 Cb2的= FALSE; 
：
} 
 NotifyPropertyChanged（CbSpecial）; 
} 
} 
公布尔Cb1的
 {
 {返回CB1; } 
组
 {
如果（价值== CB1）回报; 
 CB1 =价值; 
 NotifyPropertyChanged（Cb1的）; 
} 
} 
  

I use MS Visual 2013 Express, C#, and WPF.

In my program there are six checkboxes, and when one of them is checked, the other five should get unchecked.

I googled the last two hours, but can't find a solution as a beginner in C#. In java, i would just write checkbox1.setSelected(false);

I added a clickevent, a checked and unchecked evet in the C# code. I added Checked and Unchecked in the .xaml, but I don't know hot to get it to work.

Hope you can help me :)

=======================

My solution:

Thank you for your help. I tried some random stuff with "IsChecked" you suggested and get it to work luckily.

.Xaml looks like:

            <CheckBox x:Name="CheckBox1" ... Checked="CheckBox1_Checked"  />
            <CheckBox x:Name="CheckBox2" ... Checked="CheckBox2_Checked"  />
            <CheckBox x:Name="CheckBox3" ... Checked="CheckBox3_Checked"  />
            <CheckBox x:Name="CheckBox4" ... Checked="CheckBox4_Checked"  />
            <CheckBox x:Name="CheckBox5" ... Checked="CheckBox5_Checked"  />
            <CheckBox x:Name="CheckBox6" ... Checked="CheckBox6_Checked"  />

C# code for CheckBox1:

    private void CheckBox1_Checked(object sender, RoutedEventArgs e)
    {
        CheckBox1.IsChecked = true;
        CheckBox2.IsChecked = false;
        CheckBox3.IsChecked = false;
        CheckBox4.IsChecked = false;
        CheckBox5.IsChecked = false;
        CheckBox6.IsChecked = false;
    }

e.g. for CheckBox2:

    private void CheckBox2_Checked(object sender, RoutedEventArgs e)
    {
        CheckBox2.IsChecked = true;
        CheckBox1.IsChecked = false;
        CheckBox3.IsChecked = false;
        CheckBox4.IsChecked = false;
        CheckBox5.IsChecked = false;
        CheckBox6.IsChecked = false;
    }

So in the end, it is a very easy task to do.

解决方案

checkbox1.IsChecked = false;

ToggleButton.IsChecked Property

I am reading it as one special that unchecks the other 5.
If you want to have just one checked at a time then RadioButton would do that.
By default you can't uncheck a RadioButton.
This would allow for all 6 unchecked.

I think binding is better and implement INotifyPropertyChanged

private Bool cbSecial = false;
private Bool cb1 = false;
private Bool cb2 = false;
public Bool CbSpecial 
{
   get { return cbSecial; }
   set 
   {
      if (value == cbSecial) return;
      cbSecial = value;
      if (cbSpecial) 
      {
          Cb1 = false;
          Cb2 = false;
          ... 
      }
      NotifyPropertyChanged("CbSpecial");
   }
}
public Bool Cb1 
{
   get { return cb1; }
   set 
   {
      if (value == cb1) return;
      cb1 = value;
      NotifyPropertyChanged("Cb1 ");
   }
}
