CustomControl DependencyProperty

[FrancisKoo]

The DependencyProperty Label is not been set.When I add two BgLabelControl in MainWindow.xaml.

Here is the code

<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center"> <local:BgLabelControl Background="Red" Label="Hello, World!" /> <local:BgLabelControl Background="green" Label="www, World!" /> </StackPanel>

Here is the link

Expected

the red one show Hello, World!
the green one show www, World!
