多个依赖属性

Multiple Dependency Properties

我目前正在开发一个用户控件,并且坚持使用依赖对象的自定义属性 class IsEnabled 被识别但不是 FooText

XAML:

<ScrollViewer VerticalScrollBarVisibility="Hidden" HorizontalScrollBarVisibility="Hidden" 
                   sc:TouchScrolling.IsEnabled = "true" 
                   Grid.Row="0" Grid.Column="1">

我需要在 sc:TouchScrolling 元素上设置更多属性,但是 VS 一直抱怨找不到 属性.

TouchScrolling 元素继承自 Dependency Object

public class TouchScrolling : DependencyObject
    {
        public bool IsEnabled
        {
            get { return (bool)GetValue(IsEnabledProperty); }
            set { SetValue(IsEnabledProperty, value); }
        }

public static readonly DependencyProperty IsEnabledProperty =
            DependencyProperty.RegisterAttached("IsEnabled", typeof(bool), typeof(TouchScrolling), new UIPropertyMetadata(false, IsEnabledChanged));


//FooText is not recognized
  public string FooText
        {
            get { return (string)GetValue(FooTextProperty); }
            set { SetValue(FooTextProperty, value); }
        }

您似乎缺少 FooText DependencyProperty...

public static readonly DependencyProperty FooTextProperty =
            DependencyProperty.RegisterAttached("FooText", typeof(string), typeof(TouchScrolling), null);
