我有一个用户控件。它有一个TextBlock
. 我想在其中绑定文本
<UserControl x:Class="PhoneApp1.MyUserControl"
DataContext="{Binding RelativeSource={RelativeSource Self}}">
<StackPanel Width="200" Height="200" Background="Red">
<TextBlock Text="{Binding Text}" />
</StackPanel>
</UserControl>
在MyUserControls.xaml.cs
public partial class MyUserControl : UserControl
{
public MyUserControl()
{
InitializeComponent();
}
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register(
"Text",
typeof(string),
typeof(MyUserControl),
new PropertyMetadata(null));
public string Text
{
get { return (string)GetValue(TextProperty); }
set
{
SetValue(TextProperty, value);
}
}
}
当我绑定到ListBox
它时无法正常工作
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="mainListBox" ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<local:MyUserControl Text="{Binding Text}" Margin="5"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
和 MainPage.xaml
public partial class MainPage : PhoneApplicationPage
{
ObservableCollection<User> list = new ObservableCollection<User>();
public MainPage()
{
InitializeComponent();
User user = new User("Thanh");
list.Add(user);
list.Add(new User("lfjlkgj"));
DataContext = list;
}
}
public class User
{
public string Text { get; set; }
public User(string name)
{
Text = name;
}
}
如何正确绑定到用户控件?谢谢!!!
