这是我的代码,
<StackPanel HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,43,43,0">
<mine:MiniListView x:Name="Mini" Width="300" Headers="{Binding MyHeaders}"></mine:MiniListView>
<Button HorizontalAlignment="Right" Margin="0" FontSize="10" Content="Add Row" Width="70" Height="20" />
</StackPanel>
守则背后:
public Dictionary<string, string> MyHeaders
{
get
{
Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add("NAME", "BRANCH"); dic.Add("BANKNAME", "Percentage");
return dic;
}
}
我的自定义类:ministView
public class MiniListView : ListView
{
public static DependencyProperty HeadersProperty;
public Dictionary<string, string> Headers
{
get { return (Dictionary<string, string>)base.GetValue(HeadersProperty); }
set { base.SetValue(HeadersProperty, value); }
}
public MiniListView()
{
HeadersProperty = DependencyProperty.Register("Headers", typeof(Dictionary<string, string>), typeof(MyListView));
this.View = MyGrid();
}
}
在这里,我试图将MyHeaders绑定到HEADER'S PROPERTY,收到此错误
无法在“MiniListView”类型的“标头”属性上设置“绑定”。 '绑定'只能在DependencyProperty上设置 一个DependencyObject。
请告诉我我的代码有什么问题。
谢谢,

Owner type
不正确。它应该是MiniListView
而不是MyListView
HeadersProperty = DependencyProperty.Register("Headers",
typeof(Dictionary<string, string>), typeof(MiniListView));
