我有以下ObservableCollection:
private ObservableCollection<Tuple<UInt32, String, String>> listValues = new ObservableCollection<Tuple<uint, string, string>>();
private Tuple<uint, string, string> selectedListValue;
我将集合绑定到ListBox:
<ListBox ItemsSource="{Binding ListValues, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
DisplayMemberPath="Item1"
SelectedItem="{Binding SelectedListValue, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
我的问题是,我得到一个例外,因为所选项目的元组没有设置器。有没有人知道这个问题的解决方法?
public Tuple<uint, string, string> SelectedListValue
{
get { return selectedListValue; }
set
{
selectedListValue= value;
NotifyPropertyChanged("SelectedListValue");
}
}
答案 0 :(得分:4)
我建议在这种情况下使用这样的类:
public class MyClass
{
public uint UintProp { get; set; }
public string FirstString { get; set; }
public string SecondString { get; set; }
}
和
private ObservableCollection<MyClass> listValues = new ObservableCollection<MyClass>();
它更灵活,并且设置了属性。
