Cannot use telerik:StyleManager in XAML

[Ye HaoChen]

Hi,

I want to change the RadWindow's theme.
But I cannot use StyleManager like this:

<telerik:RadWindow x:Class="Eurlanda.DataShire.Squid.Views.DataGridShow"
                   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                   xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                   Focusable="True" telerik:StlyeManager.Theme =""
                   Header="AcessFrom">

Please check the attachment.

But only RadGridView used StyleManager in XAML is OK. (RadWindow , RadMenu, RadDocking cannot use it.)

Telerik control version is 2013.3.1316.40
My VS version is 2013
My system is Windows 7 sp1

Thank you.

I'm so stupid.
I misspelled StyleManager.
But in the VS2012 and VS2013, intellisense function is not working when I input the telerik:StyleManager.
