我是当前的情景。 主类（控制代码隐藏）：
public class MainClass : UserControl
{
public ObservableCollection<MyItem> ListItems
{
get { return (ObservableCollection<MyItem>)GetValue(ListItemsProperty); }
set { SetValue(ListItemsProperty, value); }
}
// Using a DependencyProperty as the backing store for ListContent. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ListItemsProperty =
DependencyProperty.Register("ListItems", typeof(ObservableCollection<MyItem>), typeof(MainClass), new PropertyMetadata(new ObservableCollection<MyItem>()));
}
My Type类：
public class MyItem: ContentControl
{
#region visual
public string Text
{
get { return (string)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
}
// Using a DependencyProperty as the backing store for Text. This enables animation, styling, binding, etc...
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register("Text", typeof(string), typeof(MyItem), new PropertyMetadata(""));
public string Path
{
get { return (string)GetValue(PathProperty); }
set { SetValue(PathProperty, value); }
}
// Using a DependencyProperty as the backing store for Path. This enables animation, styling, binding, etc...
public static readonly DependencyProperty PathProperty =
DependencyProperty.Register("Path", typeof(string), typeof(MyItem), new PropertyMetadata(null));
#endregion
}
我的目标是直接在xaml中使用此集合，而wf和wft是使用控件的名称空间声明。 所以我写了一个测试页面，其中有一些属性直接在其中

在xaml MainClass页面中，我将listview的ItemSource绑定到ListItem observablecollection。 现在如果我在集合定义中尝试任何类型的数据绑定它都不起作用（如果我使用相同的数据绑定，它工作正常）。 在这个例子中，我在页面的代码后面（使用elementname“page”调用）声明了一个带有文本的名为“T”的属性。 然而，静态文本（如“LESS TIME !!”）工作正常。 奇怪的是绑定没有执行，我试图设置调试转换器，但系统从不调用它。 这是绑定不执行的方式（但后退值有效）。
注意：如果我以编程方式将内容添加到集合中，则可以正常工作。 例如：
<wf:MainClass x:Name="MainClassControl" BarListItems="{Binding ExampleBarListItem, ElementName=page}" />
其中ExampleBarListItem是ObservableCollection
谢谢
详细信息： 我试图将Text绑定到self对象，这是有效的。 例如：
<wft:MyItem x:Name="Pippo" Text="{Binding Name, FallbackValue=Bad, RelativeSource={RelativeSource Mode=Self}}"

此印刷品“Pippo”。 我不明白为什么来自elementname的常规绑定不起作用。
新也尝试使用datacontext，但没有。
