Question

I am having hard luck in trying to bind my property which is of type List to a ListBox through XAML. Note though that the list contains string arrays (string[]).

So the XAML part of code looks like this:

<ListBox Height="373" HorizontalAlignment="Left" Margin="9,65,0,0" Name="reservoirList" VerticalAlignment="Top" Width="546" 
                 ItemsSource="{Binding Wells}">
</ListBox>

and on the viewModel:

public ObservableCollection<string[]> Wells {
            get { return new ObservableCollection<string[]>(getWellsWithCoords()); }            
        }

where getWellsWithCoords() creates a list of string[].

When I ran the application what I see is – which makes sense:

string[] array
string[] array 
....

Is it possible to change the XAML code in such a way so that automatically on each row
I see the n values of the each element of the Wells list, i.e something like:

well1 value11 value12
well2 value21 value22

Add a template to your listbox:

<ListBox Height="373" HorizontalAlignment="Left" Margin="9,65,0,0" Name="reservoirList" VerticalAlignment="Top" Width="546" ItemsSource="{Binding Wells}">
<ListBox.ItemTemplate>
    <DataTemplate>
        <!--Here you bind the array-->
        <ItemsControl ItemsSource="{Binding}">
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
            <ItemsControl.ItemTemplate>
                <!--Here you bind the value of each string-->
                <DataTemplate>
                    <TextBlock Text="{Binding}" Margin="5,0"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </DataTemplate>
</ListBox.ItemTemplate>
