c# - 如何以编程方式将单击事件添加到 FrameworkElementFactory

Question

我正在尝试在代码后面以编程方式应用数据模板。我已经很好地设置了属性，但我仍然坚持如何添加点击事件。请问我该怎么做？

正在复制的 Xaml 代码

<DataTemplate>
                <telerik:RadToggleButton Content="+" 
                                         Width="20" 
                                         Height="20" 
                                         HorizontalContentAlignment="Center"                                                         
                                         VerticalContentAlignment="Center"       
                                         Click="RiskButton_OnClick"
                                         Visibility="{Binding AttachmentVisibility, Mode=TwoWay, Converter={StaticResource BooleanToVisibilityConverter}}"/>
</DataTemplate>

我现在拥有的

var toggleButton = new FrameworkElementFactory(typeof(RadToggleButton));
toggleButton.SetValue(RadToggleButton.ContentProperty, "+");
toggleButton.SetValue(RadToggleButton.WidthProperty, 20.0);
toggleButton.SetValue(RadToggleButton.HeightProperty, 20.0);
toggleButton.SetValue(RadToggleButton.HorizontalContentAlignmentProperty, HorizontalAlignment.Center);
toggleButton.SetValue(RadToggleButton.VerticalAlignmentProperty, VerticalAlignment.Center);
//toggleButton.AddHandler(); <- what goes here?

DataTemplate dt = new DataTemplate
{
    VisualTree = toggleButton
};

dt.Seal();

Answer 1

toggleButton.AddHandler(RadToggleButton.ClickEvent, new RoutedEventHandler(SomeHandler));

SomeHandler 是一个 RoutedEventHandler:

public void SomeHandler(object sender, RoutedEventArgs e) 
{
}
