自己学习WPF不是很久，现将自己做的一些小项目中用到的自定义控件整理出来，方便以后使用，不尽人意之处，还请多多批评与指导，现在就来实现**自定义ScrollViewer仿Win8滚动条**

1）横纵预览![SouthEast][]               2）MouseOver![SouthEast 1][]                  3）拖动中  ![SouthEast 2][]

<table style="width:126px; height:34px; float:left; background-color:#1d93e1"> 
 <tbody> 
  <tr> 
   <td><span style="font-size:18px"><span style="color:#ffffff"><strong>3.XAML代码</strong></span></span></td> 
  </tr> 
 </tbody> 
</table>

    182                 <RowDefinition Height="*"/>
    183                 <RowDefinition Height="Auto"/>
    184             </Grid.RowDefinitions>
    185             <ScrollBar x:Name="PART_VerticalScrollBar" AutomationProperties.AutomationId="VerticalScrollBar" Cursor="Arrow" Grid.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0" Grid.Row="0" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}" Style="{DynamicResource ScrollBarStyle1}"/>
    186             <ScrollBar x:Name="PART_HorizontalScrollBar" AutomationProperties.AutomationId="HorizontalScrollBar" Cursor="Arrow" Grid.Column="0" Maximum="{TemplateBinding ScrollableWidth}" Minimum="0" Orientation="Horizontal" Grid.Row="1" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{Binding HorizontalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportWidth}" Style="{DynamicResource ScrollBarStyle1}"/>
    187             <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding ScrollViewer.CanContentScroll}" CanHorizontallyScroll="False" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Grid.Column="0" Margin="{TemplateBinding Padding}" Grid.Row="0"/>
    188         </Grid>
    189     </ControlTemplate>

**注**：将以上代码放置资源字典或文档资源或App.xaml中都可，如果，您对该样式的颜色搭配有自己的想法，修改以下代码部分颜色值即可，更多修改，此处不再赘述

1 <ScrollViewer Template="{DynamicResource ScrollViewerStyle}" HorizontalScrollBarVisibility="Auto"VerticalScrollBarVisibility="Auto">
    2          
    3 </ScrollViewer>

可能对于大神而言这不算什么，但对于初学者还是有一定帮助的，但愿能给与一些还不是很懂的同僚一些启示，共同进步，有更多想法的还望多多批评，不吝赐教。
