任何人都可以帮助我如何将上述 Xaml 代码写入 C# 背后的代码。我将此代码用于饼图标签模板。
回答by ntohl
I don't what is the binding source, or how the Pie Chart LabelTemplate (converter) look like. The best I can come up with that much information is the following:
我不知道绑定源是什么，也不知道饼图 LabelTemplate（转换器）的样子。我能想出的最好的信息如下：
public class LabelTemplate : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
//...
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
//...
}
}
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
LabelTemplate labelTemplateConverter = new LabelTemplate();
Binding binding = new Binding("Item.Items");
binding.Converter = labelTemplateConverter;
txtBlock.SetBinding(TextBlock.TextProperty, binding);
}
}
and Your textblock have the Name txtBlock
并且您的文本块的名称为 txtBlock
I hope this helps.
我希望这有帮助。
