如何将ObservableCollection绑定到XAML中的IList属性？

Question

I have IList property to get ItemSource of my DropDown list. How can I bind a ObservabelCollection to IList property in view(XAML)? I tried normal binding but it throws null reference exception.

Note: I can able to bind collection in code behind. I am getting exception only when I try to bind it through Xaml.

I tried with collections of type ObservableCollection, IList and IEnemerable

IList Property

    public IList ItemsSource
    {
        get { return this.itemsSource; }
        set { this.itemsSource = value; }
    }

Colletion

    public IList<Address> AddressSource
    {
        get { return this.address; }
        set { this.address = value; }
    } 

Xaml view

<DataForm Editor="DropDown" ItemsSource="{Binding AddressSource}" Name="Country"/>

Answer 1

It's not because you aren't able to bind but it's not able to find the property . Do check the BindingContext if it is set to appropriate level and postcode would really be helpful

Answer 2

To add Binding feature to your Application you can use trick by adding Loaded event in constructor of your Xaml Page and inside this event you need add the same code below in OnLoaded Event .

public MainPage()
{
    this.InitializeComponent();
    this.Loaded += OnLoaded;
}

private void OnLoaded(object sender, RoutedEventArgs e)
{
    this.DataContext = this;
}
