如何使listview项拖放 [英] How to make listview item drag and drop

问题描述

大家好，我正在研究.net中的一个项目。需要使用动态控件创建动态表单。就像Visual Studio中的Toolbox一样，我想用asp.net中的拖放功能创建一个带有Label，Literal，Checkbox等基本控件的工具箱。可以从工具箱拖动控件，可以放在窗体的右侧，可以创建动态窗体。请各位建议我如何实现它。



提前致谢。



我是什么尝试过：



我可以通过onclick listview项目移动listview项目，但我必须拖放。

推荐答案

这不是一件容易的事，除非客户端脚本是您的专业领域。



拖放功能是客户端的事情。这意味着您需要使用 JavaScript 来执行此操作。您可以查找具有拖放功能的 JavaScript 库，这样您就可以省时间滚动自己的 JavaScript 从头开始的代码。一个例子是使用 jQuery 拖放式UI功能： Draggable | jQuery UI [ ^ ]和droppable：可信的| jQuery UI [ ^ ]



这是我发现的一个使用jQuery来启用ListView中的拖放： 使用jQuery拖放ListView项目

Well it's not an easy task to do, not unless if client-side scripting is your area of expertise.

The "drag-and-drop" feature is a client-side thing. This means that you would need to use JavaScript to perform that. You can look for a JavaScript library that has drag-and-drop feature so you'll save your time rolling your own JavaScript code from scratch. One example is using jQuery drag-drop UI feature: Draggable | jQuery UI[^] and droppable: Droppable | jQuery UI[^]

Here's one I found that uses jQuery to enable drag-and drop in ListView: Drag and drop ListView item using jQuery
