WPF FrameworkElementFactory 图像创建无法为 MouseDownEvent 添加处理程序
我正在使用 Framework ElementFactory 在 DataTemplate 中创建图像。在尝试处理 Image 类型的 MouseDown 事件时，抛出异常 - “Handler Type is not valid.
How can we add an MouseDownEventHandler for the FrameworkElementFactory of type Image
FrameworkElementFactory imageSecondaryContent = new FrameworkElementFactory(typeof(Image));
imageSecondaryContent.SetValue(Image.WidthProperty, imgWidth);
imageSecondaryContent.SetValue(Image.VisibilityProperty, Visibility.Hidden);
imageSecondaryContent.Name = imageName;
Binding tmpBindingSecondaryContent = new Binding();
tmpBindingSecondaryContent.Source = IconLibary.GetUri(IconStore.ExclaminationPoint);
imageSecondaryContent.SetBinding(Image.SourceProperty, tmpBindingSecondaryContent);
imageSecondaryContent.AddHandler(Image.MouseDownEvent, new RoutedEventHandler(Test));
最后一行抛出异常。请帮助
