Listing 11-7. Duration Editor Control

File:ApressControlsVB\DurationEditor.xaml

<UserControl

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:local="clr-namespace:ApressControlsVB"

x:Class="ApressControlsVB.DurationEditor"

mc:Ignorable="d">

<Grid x:Name="LayoutRoot" Background="White">

<local:DurationEditorInternal

Duration="{Binding Value, Mode=TwoWay}"/>

</Grid>

</UserControl>

In the code that’s shown, Visual Studio adds the local namespace when you drag the DurationEditorInternal control onto your screen. If you’re re-creating this example by directly retyping the XAML that’s shown in this book, you’ll need to make sure that you enter the correct class names.

The definition of the DurationEditorInternal control within the XAML allows you to data-bind the “normal” Duration property by specifying the binding path Value.

You’re now ready to build your ApressControls project. Save the output file (ApressControls.DLL) into a location that you can refer to later.

Tip Creating a wrapper control provides a simple, declarative way to bind a custom control to the data context. If you prefer not to create two controls, another way to achieve this is to create a custom control that includes a call to SetBinding in its constructor.
