如何将PostBack数据提取到动态添加的UserControl(.NET)中? [英] How to pull PostBack data into a dynamically added UserControl (.NET)?

问题描述

我的页面上有一个面板:

I have a Panel on my Page:

<asp:Panel ID="pnlTest" runat="server" />

然后我在Page_Load上向其动态添加一个文本框:

Then I dynamically add a TextBox to it on Page_Load:

    TextBox simpleTextBox = new TextBox();
    pnlTest.Controls.Add(simpleTextBox);
    simpleTextBox.ID = "SimpleTextBox-1";

是否有一种方法可以提取此TextBox中键入的信息，而不必直接从Request.Form中提取它?再次添加后，我以为可以做以下事情:

Is there a way to pull in the information typed in this TextBox without pulling it directly from Request.Form? I thought I could do something like this after I added it again:

lblPresentResults.Text = myTextBox.Text;

我知道这个示例似乎是人为的，但是我认为我会尝试消除特定应用程序中的所有其他变量，尤其是在这里问一个问题.

I know this example seems contrived, but I figured I'd try to eliminate all the other variables in my specific application, especially to ask a question here.

推荐答案

您需要在加载视图状态之前(例如在Page_Init中)添加文本框，并且您应该能够做到这一点.

You need to add the textbox before viewstate loads, such as in Page_Init, and you should be able to do this.
