WP7 Custom User Control Property

Question

I want a user control called Segmented Panel that contains 3 buttons of which I want to modify their names (Title1/2/3) from a XAML screen.

MainPage XAML:

<local:SegmentedControl HorizontalAlignment="Left" Margin="43,62,0,0" x:Name="segmentedControl1" VerticalAlignment="Top" Title1="ENTER BUTTON NAME HERE" Title2="blah.." Title3="Last Button" Loaded="segmentedControl1_Loaded" />

SegmentedControl XAML.CS:

public static readonly DependencyProperty Title1Property
        = DependencyProperty.RegisterAttached("Title1", typeof(String), typeof(StackPanel),
        new PropertyMetadata(""));

    public static void SetTitle1(UIElement element, String value) {
        element.SetValue(Title1Property, value);
    }
    public static string GetTitle1(UIElement element) {
        return (string)element.GetValue(Title1Property);
    }

    public string Title1 {
        get { return GetValue(Title1Property).ToString(); }
        set { SetValue(Title1Property, value); }
    }

In expression blend I open up the Segmented Panel, choose button1, in Content I tried chosing both Data Context and Element Value, then scrolling down to choose "Title1", but when I compile it, the button's contents never changes.

Can anybody help me out?

Hi,

as John Gardner suggests, you have to write ...typeof(SegmentedControl) in your dependency property implementation and then one have to bind the property to the appropiate UI element!

For example:

<local:SegmentedControl HorizontalAlignment="Left" Margin="43,62,0,0" x:Name="segmentedControl1" VerticalAlignment="Top" Title1="{Binding Title1}" ... Loaded="segmentedControl1_Loaded" />
