UWP 中没有 IsManipulationEnabled 属性 [英] No IsManipulationEnabled property in UWP

问题描述

我有一个 UWP 应用程序，我试图在其中启用 UI 元素上的操作事件.我订阅了 ManipulationStarted 事件，但意识到它没有触发.然后，根据一些建议，我尝试在 Grid 上设置 IsManipulationEnabled 属性，但开始收到编译错误，提示找不到 IsManipulationEnabled 属性.我错过了什么吗?

I have a UWP application where I am trying to enable manipulation events on the UI elements. I subscribed to the ManipulationStarted event but realized that it was not firing. Then, based on some suggestions, I tried setting IsManipulationEnabled property on the Grid but started getting compilation error saying that IsManipulationEnabled property could not be found. Am I missing out on something?

推荐答案

IsManipulationEnabled 是 WPF 属性.为了在 UWP 中获取操作事件，您必须设置 ManipulationMode 属性.

IsManipulationEnabled is a WPF property. In order to get manipulation events in UWP, you'll have to set the ManipulationMode property.

来自的备注部分ManipulationMode 页面:

您必须将 ManipulationMode 设置为 System 或 None 以外的值如果要处理 ManipulationStarted 等操作事件来自应用代码中的 UI 元素.

You must set the ManipulationMode to a value other than System or None if you want to handle manipulation events such as ManipulationStarted from UI elements in your app code.

例如

ManipulationMode = ManipulationModes.Scale
    | ManipulationModes.TranslateX
    | ManipulationModes.TranslateY
    | ManipulationModes.TranslateInertia;
