Question

Hey.
I’ve having some trouble with binding in XAML. I have a list of Player objects. I would like this list to be bound to a ListBox and display the Name of the Player. At the moment, the List box is being filled with Red.Player (i.e. the object type and namespace). My resource dictionary style looks like this:

<Style x:Key="PlayerListBox" TargetType="ListBoxItem">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="BorderBrush" Value="Transparent"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="VerticalContentAlignment" Value="Top"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBoxItem">
                    <Border x:Name="LayoutRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}" d:DesignWidth="231" d:DesignHeight="50">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal"/>
                                <VisualState x:Name="MouseOver"/>
                                <VisualState x:Name="Disabled">
                                    <Storyboard>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="LayoutRoot">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource TransparentBrush}"/>
                                        </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                            <VisualStateGroup x:Name="SelectionStates">
                                <VisualState x:Name="Unselected"/>
                                <VisualState x:Name="Selected"/>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <TextBlock TextWrapping="Wrap" Text="{Binding}" FontSize="29.333" TextAlignment="Center"/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I guess the main part is this:

<TextBlock TextWrapping="Wrap" Text="{Binding}" FontSize="29.333" TextAlignment="Center"/>

I tried using Text="{Binding Name}" but then nothing shows up at all. I’m setting the ItemsSource when the user selected a player:

PlayerList.ItemsSource = ListofPlayers;

Thanks for any help

Answer 1

Is Name a public property on the type you’ve bound to?

ie

public class Person
{
    string name;
    int age;

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    public int Age
    {
        get { return age; }
        set { age = value; }
    }

}
