我的目标是制作一个这样的滑块:
问题是,当我将滑块移动到它的最大值时,三角形的点不会达到最大值的顶部,它保持如下:
我相信它的原因是因为Thumb's
位置仅限于它的大小所以它不能超出滑块的限制....但在我的这正是我想要实现的!我尝试更改Thumb
高度,但这可能有助于Top
,但这会在滑块的Bottom
中出现问题。
我的代码中缺少什么?
到目前为止我的代码是:
The Slyder:
<Slider Grid.Row="1"
Grid.Column="1"
Maximum="1000"

我通过编辑默认模板来制作它们。
答案 0 :(得分:3)
您可以做的最简单的调整是设置10
的上边距(Path
的高度的一半),以便将轨道背景放下足以让三角形笔尖匹配:
<UniformGrid x:Name="TrackBackground" Rows="6" Columns="0"
Margin="0,10,0,0">
<!-- ... -->
</UniformGrid>
UniformGrid的位置超过1个,因此请相应地进行编辑。
