LoadViewState没有解雇我的用户控件 [英] LoadViewState not fired on my user control

问题描述

我有嵌套在一个中继器的用户控件。
我里面的用户控件我有另一个中继和我有一个面板。

I have a user control nested in a repeater. Inside my user control I have another repeater and in that I have a panel.

我想我的覆盖用户控件的LoadViewState事件，并动态地将控件添加到面板上。我想这样做的LoadViewState，使动态控制得到ViewState获取加载前加入，所以他们回发后保留它们的值。

I am trying to override the LoadViewState event of my user control and dynamically add controls to the panel. I want to do it in the LoadViewState so that the dynamic controls get added before the viewstate gets loaded, so they retain their values after post backs.

由于某种原因，用户控件（ASCX）的LoadViewState事件不会开火。是否有某种方式来迫使其火，还是有我可以用另一种方法？我已经排除了用户控制中继器数据绑定的事件，因为我需要它，即使数据绑定不发生工作，我不能做到这一点的中继项创建活动或者是因为孩子面板和内部HTML不存在然而。

For some reason the LoadViewState event on the user control (ascx) is not firing. Is there some way to force it to fire, or is there another method I could use? I have ruled out the user controls repeater databind event, because I need it to work even if data binding isn't happening and I can't do it on the repeaters item created event either because the child panel and inner html doesn't exist yet.

推荐答案

LoadViewState 不是添加子控件中的适当位置。对于用户控件内动态添加控件，你要看看<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.control.createchildcontrols.aspx\">CreateChildControls方法。

LoadViewState isn't the appropriate place for adding child controls. For dynamically adding controls within a user control, you'll want to look at the CreateChildControls method.

这不是发射了 LoadViewState 事件，因为你需要保存至少在一个值的ViewState 有事件火灾。

It's not firing a LoadViewState event because you need to save at least one value in the ViewState to have the event fire.
