WPF自定义控件之仿Win8滚动条--ScrollViewer

1.说明

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

2.效果预览

1）横纵预览 2）MouseOver 3）拖动中

3.XAML代码

    <!--x:Key="ScrollBarThumb" TargetType="{x:Type Thumb}"-->

     <SolidColorBrush x:Key="ThumbBorderBackground" Color="#FFCDCDCD"/>

     <SolidColorBrush x:Key="ThumbMouseOverBackground" Color="#FF959393"/>

     <SolidColorBrush x:Key="ThumbDraggingBackground" Color="#FF505050"/>

    <!--x:Key="ScrollBarStyle1" TargetType="{x:Type ScrollBar}"-->

     <!--1,垂直与水平值相反-->

     <sys:Double x:Key="PepeatButtonPathWidth">8</sys:Double>

     <sys:Double x:Key="PepeatButtonPathHeight">6</sys:Double>

     <!--2,垂直与水平值一样-->

     <SolidColorBrush x:Key="PepeatButtonPathFill" Color="#FF444F4F"/>

         </Grid>

     </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

    <!--x:Key="ScrollBarThumb" TargetType="{x:Type Thumb}"-->

     <SolidColorBrush x:Key="ThumbBorderBackground" Color="#FFCDCDCD"/>

     <SolidColorBrush x:Key="ThumbMouseOverBackground" Color="#FF959393"/>

     <SolidColorBrush x:Key="ThumbDraggingBackground" Color="#FF505050"/>

    <!--x:Key="ScrollBarStyle1" TargetType="{x:Type ScrollBar}"-->

     <!--1,垂直与水平值相反-->

     <sys:Double x:Key="PepeatButtonPathWidth">8</sys:Double>

     <sys:Double x:Key="PepeatButtonPathHeight">6</sys:Double>

     <!--2,垂直与水平值一样-->

     <SolidColorBrush x:Key="PepeatButtonPathFill" Color="#FF444F4F"/>

     <SolidColorBrush x:Key="PepeatButtonPathMouseOverFill" Color="Black"/>

     <SolidColorBrush x:Key="PepeatButtonMouseOverBackground" Color="#FFDEDCDC"/>

     <SolidColorBrush x:Key="ScrollBarDisabledBackground" Color="#F4F4F4"/>

     <SolidColorBrush x:Key="ScrollBarBackground" Color="#F4F4F4"/>

4.应用

 <ScrollViewer Template="{DynamicResource ScrollViewerStyle}" HorizontalScrollBarVisibility="Auto"VerticalScrollBarVisibility="Auto">

      <!--包含的控件-->

 </ScrollViewer>

5.总结

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。
