C# WPF : slider going to exact position
提问by TheQuestioner
I'm using a slider in a WPF window and I want that when the user clicks somewhere on the track of the slider, the thumb to go to that exact position. Currently, when I click somewhere, the thumb goes towards that position, but not to exactlythat position. How can I achieve what I want ?
我在 WPF 窗口中使用了一个滑块，我希望当用户单击滑块轨道上的某个位置时，拇指移动到该确切位置。目前，当我点击某处时，拇指会朝向那个位置，但不会完全到达那个位置。我怎样才能达到我想要的？
Edit: An example to better explain what I want: If the thumb is at 10 and I press the mouse down near 100 , I want it to jump to 100 (without passing through other values).
编辑：一个更好地解释我想要什么的例子：如果拇指在 10 并且我在 100 附近按下鼠标，我希望它跳到 100 （不通过其他值）。

you need to set IsMoveToPointEnabledto True: http://msdn.microsoft.com/en-us/library/system.windows.controls.slider.ismovetopointenabled.aspx
您需要设置IsMoveToPointEnabled为True：http: //msdn.microsoft.com/en-us/library/system.windows.controls.slider.ismovetopointenabled.aspx
Slider.IsMoveToPointEnabledGets or sets a value that indicates whether the Thumb of a Slider moves immediately to the location of the mouse click that occurs while the mouse pointer pauses on the Slider track.
Slider.IsMoveToPointEnabled获取或设置一个值，该值指示当鼠标指针在 Slider 轨道上暂停时，Slider 的 Thumb 是否立即移动到鼠标单击的位置。

You should handle slider thumb mouse enter event and define behvior you want.
您应该处理滑块拇指鼠标输入事件并定义您想要的行为。
var thumb = (slider1.Template.FindName("PART_Track", slider) as Track).Thumb;
thumb.MouseEnter += new MouseEventHandler(ThumbMouseEnter);
Then you set position of the thumb in ThumbMouseEnter event hendler. THis will allow you to define any behavior you want.
然后在 ThumbMouseEnter 事件处理程序中设置拇指的位置。这将允许您定义您想要的任何行为。
