What approaches are available to dummy design-time data in WPF?

by

Using VS2010 you can use Design-Time attributes (works for both SL and WPF). I usually have a mock data-source anyway so it’s just a matter of:

  • Adding the namespace declaration

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

  • Adding the mock data context to window/control resources

    <UserControl.Resources>
  <ViewModels:MockXViewModel x:Key="DesignViewModel"/>
</UserControl.Resources>

  • Setting design-time data context

    <Grid d:DataContext="{Binding Source={StaticResource DesignViewModel}}" ...

Works well enough.
