在ASP.NET回发问题 [英] Postback issue in ASP.NET

问题描述

我有它的Visible属性设置为false一个asp.net标签控件。在code-背后，我的知名度设置为基于用户是否已经或未登录真/假。一个怪异的行为是上回发时，code-后面执行，并设置标签的可见性的价值什么的，然后标记执行并设置标签的可见性设置为false。在非回发请求，状态由code-背后设置是的不的覆盖。请原谅我的无知，但我失去了一些重要的东西？

I have an asp.net label control with its Visible property set to false. In the code-behind I'm setting its visibility to true/false based on whether the user has logged in or not. A weird behavior is that on postbacks, the code-behind executes and sets the value of the label's visibility to whatever, and then the markup executes and sets the label's visibility to false. On non-postback requests, the status set by the code-behind is not overwritten. Pardon my ignorance, but am I missing something important?

推荐答案

让我们来了解页面的生命周期，并在各种页面事件被解雇运行

Get to know the page lifecycle, and when the various page events are fired by the runtime.

另外，我不认为code是微不足道的。如果它是codeD正确，你就不会遇到这个问题。把它放在这里，让我们来看看。

Also, I don't think the code is insignificant. If it were coded properly, you wouldn't be experiencing this problem. Put it up here and let us have a look.
