[UWP] [C＃] [XAML]从ListViewBase拖动项目 [英] [UWP][C#][XAML] Drag items from ListViewBase

问题描述

大家好，我有一个关于从ListViewBase拖放项目的问题。

Hi everyone, I have a question about dragging and dropping items from ListViewBase.

有没有办法在使用ListViewBase的DragItemsStarting事件时修改拖动UI？我的一些物品非常大，我想在拖动时让它们变小，只是它的一个小版本。是否有可能？

Is there a way to modify drag UI when using DragItemsStarting event of ListViewBase? Some of my items are pretty big and I'd like to have them smaller when dragging, just a small version of it. Is it possible?

另一个问题是： 是否可以拦截桌面的DraOver事件？当我需要将项目拖动到桌面时，我还会在拖动时修改UI和一些文本。 

And another issue is: is it possible to intercept DraOver event for Desktop? When I need to drag item to desktop I would also modify UI and some text while dragging. 

推荐答案

您好AvelN，

Hi AvelN,

欢迎来到开发通用Windows应用程序
论坛！

据我所知，无法修改拖动UI以使项目更小，但我们可以使用

DragUIOverride.SetContentFromBitmapImage 创建方法来自提供的BitmapImage的可视元素来表示dra在拖放操作中使用gged数据来实现UI自定义。

As far as I known, it is not possible to modify the drag UI to make the item to be smaller, but we can use DragUIOverride.SetContentFromBitmapImage methods to create a visual element from a provided BitmapImage to represent the dragged data in a drag-and-drop operation to implement the UI Customization.

有关详细信息，请尝试参考此官方示例中的Scenario2_DragUICustomization：XamlDragAndDrop 。

For more information, please try to refer to the Scenario2_DragUICustomization in this official sample:XamlDragAndDrop.

最好的问候，

Amy Peng
