在C# WPF下自定义滚动条ScrollViewer样式的操作

c# 搞代码 4年前 (2022-01-09) 24次浏览 已收录 0个评论

一、实现对ScrollViewer样式的自定义主要包括:

1、滚动条宽度设置

2、滚动条颜色

3、滚动条圆角

4、滚动条拉动时的效果mouseover

二、实现效果:

三、实现方法

1、创建资源字典( ResourceDictionary)文件

由于style代码比较多,之间在控件文件中加载style比较混乱,也不利于其它窗口复用,这里单独创建了ScrollViewDictionary.xaml文件代码如下:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
