[英]Listbox Databinding Not working
我無法弄清楚為什么數據綁定不能按預期工作:
但是,數據綁定仍然無法正常工作。 我的列表框:
<ListBox Height="425" ItemsSource="{Binding headers}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=HeaderInfo}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
后面的代碼:
public partial class cornet_controls : PhoneApplicationPage
{
public ObservableCollection<headerInfo> headers;
public cornet_controls()
{
InitializeComponent();
this.DataContext = this;
headers = new ObservableCollection<headerInfo>();
for (int x = 0; x < 100; x++)
headers.Add((new headerInfo() { HeaderInfo = x.ToString() }));
}
}
我的自定義類實現了INotifyPropertyChanged:
public class headerInfo : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public headerInfo()
{}
private String _HeaderInfo;
public String HeaderInfo
{
get { return _HeaderInfo; }
set { _HeaderInfo = value; NotifyPropertyChanged("HeaderInfo"); }
}
private void NotifyPropertyChanged(String propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
您不能綁定到NonProperty:
<ListBox Height="425" ItemsSource="{Binding headers}">
public ObservableCollection<headerInfo> headers;
您需要綁定到以下屬性:
public ObservableCollection<headerInfo> headers { get; set; }
