How to bind my listbox to a partial class of itself?

Question

I have a small problem, suppose I have the following MainWindow.xaml:

<Window x:Class="DragDrop.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        <ListBox Name="ListBoxLeft"  />
        <ListBox Name="ListBoxRight"  Grid.Column="1" />
    </Grid>
</Window>

and now I would simply like bind <ListBox Name="ListBoxLeft" /> to my property public List<User> UserListLeft;. How can I achieve this? How should I specify the DataContext?

All properties are just simply listed in MainWindow.xaml.cs.

Note: I do not use the MVVM model.

Thanks

In the constructor of your MainWindow.xaml.cs add:

DataContext=this;

then in your MainWindow.xaml, add:

 <ListBox Name="ListBoxRight"  Grid.Column="1" ItemSource={Binding UserListLeft} />

Please make your UserListLeft as an ObservableCollection, instead of List. To be able to notify any change to the view.

Dear Alvaro, thank you for your kind response. I was wondering whether it was also possible to do the DataContext=this; part in XAML.

@Snowflake So what you want to do can't be called a "Binding". In this case, I suggest for you to fill it Manually, in the "Set method" of your UserListLeft property. each time you add an "Item" to your list, add also : ListBoxRight.Items.add(YourItem);

In XAML top / Window DataContext="{Binding RelativeSource={RelativeSource self}}"

Also, you should have the mainWindow implement INotifyPropertyChanged
