XAML代码中的C#变量

我有一个XAML表单的部分类代码。下面是隐藏的代码：

partial class GalleryDictionary
{
    private void GalleryItemLabelPropertyChanged(object sender, RoutedEventArgs e)
    {
        var mainWindow = Application.Current.MainWindow as MainWindow;
        if (mainWindow == null)
            return; 

        var tb = sender as TextBox;
        if (tb == null)
            return;

        var sip = tb.DataContext as StereoImagePair;
        if (sip == null)
            return;

        sip.Label = tb.Text;

        mainWindow.Db.SubmitChanges();
    }
}

    private void DS_Loaded(object sender, RoutedEventArgs e)
    {
        ToggleButton tg = sender as ToggleButton;
        if (//WhateverYourPathToTheVariable//.DriveOnRight == "True")
        {
            tg.Content = "DS"; 
        }
        else
        {
            tg.Content = "PS";
        }

    }

这是名称空间声明之后的整个DOC.XAML.CS文件

在我的XAML文件中，我需要从这个XAML.CS文件中访问一个变量，我想调用DriveOnRight。这是我一直在奋斗的路线：

        <ToggleButton Grid.Row="1" Grid.Column="2" Width="26" Height="26" IsChecked="True" Click="GalleryItemLabelPropertyChanged" CommandParameter="2" Name="PS" Content="{Binding DriveOnRight}"></ToggleButton>

XAML文件读取的地方是….Content=“{Binding DriveOnRight}”，我需要从CS文件访问变量并在那里显示它

我该怎么做

任何帮助都将不胜感激。

这里有一种方法：

public class GalleryDictionaryViewmodel: INotifyPropertyChanged
{
     private string _DriveOnRight;
     public string DriveOnRight
     {
         get{ return _DriveOnRight;}
         set{ _DriveOnRight = value;}
     }
}

在代码隐藏文件（DOC.XAML.CS）中：

在Xaml文件中：

 <ToggleButton Grid.Row="1" Grid.Column="2" Width="26" Height="26" IsChecked="True" Click="GalleryItemLabelPropertyChanged" CommandParameter="2" Name="PS" Content="{Binding DriveOnRight}"></ToggleButton>

希望这能对您有所帮助。

鉴于这在您的代码背后，为了与您的方法保持一致，您可以使用依赖属性作为您的值

public string DriveOnRight
{
    get { return (string)GetValue(DriveOnRightProperty); }
    set { SetValue(DriveOnRightProperty, value); }
}
public static readonly DependencyProperty DriveOnRightProperty =
    DependencyProperty.Register("DriveOnRight", typeof(string), typeof(GalleryDictionary));

尽管我建议Krish的设计更适合使用ViewModel。

您可以在代码中指定一个值，该值与按钮或切换按钮或任何使用它的对象的加载功能相关

在函数上方的某个级别中设置值，使代码如下所示

    public static string DriveOnRight = "True";  
    //"True" could be a condition or function or whatever.

然后，在代码隐藏中可能是这样的：

partial class GalleryDictionary
{
    private void GalleryItemLabelPropertyChanged(object sender, RoutedEventArgs e)
    {
        var mainWindow = Application.Current.MainWindow as MainWindow;
        if (mainWindow == null)
            return; 

        var tb = sender as TextBox;
        if (tb == null)
            return;

        var sip = tb.DataContext as StereoImagePair;
        if (sip == null)
            return;

        sip.Label = tb.Text;

        mainWindow.Db.SubmitChanges();
    }
}

    private void DS_Loaded(object sender, RoutedEventArgs e)
    {
        ToggleButton tg = sender as ToggleButton;
        if (//WhateverYourPathToTheVariable//.DriveOnRight == "True")
        {
            tg.Content = "DS"; 
        }
        else
        {
            tg.Content = "PS";
        }

    }

然后…在XAML代码中，您有：

        <ToggleButton Loaded="DS_Loaded" Grid.Row="1" Grid.Column="0" Width="26" Height="26" Name="DS" Content="DS"></ToggleButton>
