1.关于ApplicationBar

代码控制是否可用 (this.ApplicationBar.Buttons[2] as ApplicationBarIconButton).IsEnabled = true;

2.ControlTemplate和 DataTemplate

所有的Control都定义了一个ControlTemplate类型的名字叫做Template的属性。

    

关于ContentPreseter，自己定义content之后就会屏蔽原来的ContentPresenter,所以需要自己手动再写.

3.ContentControl定义了Content属性，像Button这些都是从ContentControl继承来的，如果在里面放变量，会自动调用该类型的tostring方法解析，所以应该放Templdate。

4.The TemplateBinding is syntactically very simple. It always targets a dependency property in the visual tree of the template.

<Button Content="Click me!" HorizontalAlignment="Center" VerticalAlignment="Center" BorderBrush="{StaticResource PhoneAccentBrush}" BorderThickness="6">
       <Button.Template> 
               <ControlTemplate TargetType="Button"> 
                          <Border BorderBrush="{TemplateBinding BorderBrush}"   BorderThickness="{TemplateBinding BorderThickness}"> 
                                   <TextBlock Text="temporary" /> 
                          </Border> 
               </ControlTemplate> 
       </Button.Template> 
</Button>

is a short-cut for
BorderBrush="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=BorderBrush}"

5.关于市场提交

所有工程的AssemblyInfo.cs，修改到这个 [assembly: NeutralResourcesLanguageAttribute("en")]
6.Visual State Manager

 Button的VisualState定义

[TemplateVisualStateAttribute(Name = "Disabled", GroupName = "CommonStates")] 

[TemplateVisualStateAttribute(Name = "Normal", GroupName = "CommonStates")] 

[TemplateVisualStateAttribute(Name = "MouseOver", GroupName = "CommonStates")] 

[TemplateVisualStateAttribute(Name = "Pressed", GroupName = "CommonStates")] 

[TemplateVisualStateAttribute(Name = "Unfocused", GroupName = "FocusStates")] 

[TemplateVisualStateAttribute(Name = "Focused", GroupName = "FocusStates")] 

public class Button : ButtonBase

　在ControlTemplate中定义VisualState 并且可以定义成StoryBoard类型。
