书上常用的方法是布局法，用grid布局，将控件放在grid格子里，格子的大小决定控件的大小，一般不会用<StackPanel>布局，任何控件放在里面，大小都会平均分配，即便是设置了某个控件的大小，稳定性还是很难控制的。每个控件都有with和height属性。

如果想自定义一张图片，可以把背景改一下，好像不太好看。也可以加个标签。<Slider ><ControlTemplate></ControlTemplate></Slider >,在里边可以更改控件的形状，背景，显示样式。《WPF编程》这本书里面介绍的很清楚。

slider控件是个整体的 小滑块在上面 用Grid套在外面的话 调整大小 会将整个控件弄小 而不会将上面的小滑块弄小 可能我没有理解透您的意思 方便的话可以发个例子吗 yesicoo@163.com
