Hi,
You need to add the System.Windows.Controls assembly for the app.xaml and usercontrol xaml file, for example:
1. Add the assembly for the app.xaml file.
<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="scroll.App" xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows" xmlns:primitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls" > <Application.Resources>
2. Add the assembly for the usercontrol's xaml file.
<UserControl xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" xmlns:my2="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="scroll.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <Grid x:Name="LayoutRoot" Background="White"> <local:TabControl x:Name="tabcontrol" Style="{StaticResource newTabControlStyle}" > <local:TabItem x:Name="tabitemFee" Header="first" Style="{StaticResource newTabItemStyle}" ></local:TabItem> <local:TabItem x:Name="secon" Header="first" Style="{StaticResource newTabItemStyle}" ></local:TabItem> <local:TabItem x:Name="third" Header="first" Style="{StaticResource newTabItemStyle}" ></local:TabItem> <local:TabItem x:Name="forth" Header="first" Style="{StaticResource newTabItemStyle}" ></local:TabItem> </local:TabControl> </Grid></UserControl>

I'm also having the same issue, as far as I can tell it seems to be a bug in VS2008 with Silverlight. It looks like the preview breaks if you have a style in app.xaml that has a TargetType of a control that lives in a different namespace to the default one. Is there a fix or a work around for this as it's seriously annoying to not have a preview ?
