如何在winform C＃中重新打开tabcontrol的已处理选项卡 [英] How to re-open a disposed tab of a tabcontrol in winform C#

问题描述

我在带有20个Tabs的TabControl中创建了一个包含大量控件的巨大表单。在运行时，它使用大量内存，并且在打开所有标签页时，用户对象超过了其限制10000。我想在更换标签时每次都处理最后使用的标签，但是有一个问题我们无法重新打开一个标签页。



我是什么尝试过：



i已经尝试过用户控制容器来部分加载表单控件，但它不值得......

In run time its using huge memory, and User Objects gets exceeded its limit of 10000 while opening all the tab pages. i want to dispose last used tab each time while changing the tab, but there is a problem we can't reopen a dispose tab..

What I have tried:

i have tried User Control Container to partially loading of form controls but its not worthy...

推荐答案

您不能重新打开Disposed类实例：它们依赖的资源已被回收。尝试就像拆除一张桌子，用腿作为木柴，顶部作为门，然后尝试在上面吃晚餐！这是行不通的：一旦桌子被回收，你需要买一个新的。

这是谁需要对你的标签页面做什么：根据需要创建新实例。



但老实说，我认为您的UI设计存在严重缺陷：我非常怀疑任何用户都希望查看10,000个控件，更不用说等待您的应用启动了up - 这可能需要相当长的时间来显示 - 我当然不会！

You cannot re-open Disposed class instances: the resources they rely upon have been recycled. Trying to is like dismantling a table, using the legs as firewood and the top as a door, then trying to serve dinner on it! That won't work: once the table has been recycled, you need to buy a new one.
Which is what who need to do with your tab pages: create new instances as needed.

But honestly, I think your UI design is badly flawed: I doubt very much that any user is going to want to look at 10,000 controls, let alone wait for your app to start up - which will probably take considerable time with that much to display - I certainly wouldn't!
