在不使用表格的情况下在网页上放置控件 [英] positioning controls on web page without using table

问题描述

我必须使用拖放功能在网页上动态放置控件.我使用ajax拖放控件来做到这一点.但是将页面发回时，所有控件都重新定位到左上角(0,0位置)，这是一个问题.有没有办法像在Windows .net中一样保持控件在回发中的位置或设置控件的位置.请回复.

推荐答案

您必须在部分回发期间保持位置.为此，我们需要使用Sys.WebForms.PageRequestManager Class.它有两个事件beginRequest 和endRequest.在这些事件中，您必须捕获拖动的位置，然后再次设置位置.
在这里，我对gridview做过类似的应用程序，用于在部分回发期间保持滚动位置.

You have to maintain the position during partial postback. For that we need to use Sys.WebForms.PageRequestManager Class . It has two eevents beginRequest and endRequest . During those event you have to trap the dragged position and then set the position again.
Here, I have done a similar application with gridview, for maintaining scroll position during partial postback.
