我要疯了试图让这个与连最基本的例子工作。 我不能为我的生命得到结合工作。 这里是不是为我工作的一个超级简单的例子。 我必须做一些不正确。
我的自定义控制在我的控制库组件:
public class TestControl : Control
{
public static readonly DependencyProperty TestPropProperty =
DependencyProperty.Register("TestProp", typeof(string), typeof(TestControl), new UIPropertyMetadata(null));
public string TestProp
{
get { return (string)GetValue(TestPropProperty); }
set { SetValue(TestPropProperty, value); }
}
static TestControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(TestControl), new FrameworkPropertyMetadata(typeof(TestControl)));
}
}
而其XAML模板:
<Style TargetType="{x:Type local:TestControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:TestControl}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<StackPanel>
<TextBlock Text="Testing..." />
<Label Content="{Binding TestProp}" Padding="10" />
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这里的XAML消费在我的控制库的引用WPF窗口控制:
<Grid>
<ItemsControl Name="mylist">
<ItemsControl.ItemTemplate>
<DataTemplate>
<my:TestControl TestProp="{Binding Path=Name}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
而这里的后面的代码:
public partial class Test2 : Window
{
public class TestObject : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string PropertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));
}
private int _id;
public int id
{
get { return _id; }
set { _id = value; OnPropertyChanged("id"); }
}
private string _Name;
public string Name
{
get { return _Name; }
set { _Name = value; OnPropertyChanged("Name"); }
}
}
public Test2()
{
InitializeComponent();
mylist.ItemsSource = new TestObject[]
{
new TestObject(){ id = 1, Name = "Tedd" },
new TestObject(){ id = 2, Name = "Fred" },
new TestObject(){ id = 3, Name = "Jim" },
new TestObject(){ id = 4, Name = "Jack" },
};
}
}
运行这个例子给我控制的四个实例,但我只看到在每一个“测试......”的TextBlock。 我的标签从来没有约束。 什么是我的误解和不正确地做?
