从控件构建动态Web列表 [英] building dynamic list of web from controls

问题描述

有没有办法在运行时动态生成说文本框控件列表

时间，基于数据库中出现的值可能会有所不同

代码运行的时间。在传统的asp中你可以运行一个循环来做这样的事情。我知道你可以使用类似

Form1.Controls.Add（TextBox1）的东西在运行时动态添加文本框但是你还需要声明每个单独的文本框控件据我所知..

这不实用，因为我不知道在运行

页面之前我需要多少。

Is there a way to generate a list of say textbox controls dynamically at run
time, based on say a value coming out of a database which could vary each
time the code is run. In traditional asp you could just have run a loop to do
something like that. I am aware in you can use something like
Form1.Controls.Add(TextBox1) to add textboxes dynamically at run time but you
still need to declare each individual textbox control as far as I can tell..
This is not practial as I don''t know how many I will need before I run the
page.

推荐答案

dim x as integer = 10''从db

for i = 1到10

dim txt as new TextBox（）

txt.Id = i.ToString（）

Form1.Controls.Add（txt）

结束

也许您可以将TextBox控件添加到更高级别的父级

控件，如Panel或甚至是Repeater。你不必在后面的代码中声明

每个TextBox控件作为类成员变量 -

你可以遍历容器中的控件并对其执行操作

他们。


有意义吗？

< sc ***** @ newsgroup.nospam> ;写道：

Perhaps you could add the TextBox controls to a higher level parent
control, like a Panel or even a Repeater. You wouldn''t have to declare
each TextBox control in the code behind as a class member variable -
you could loop through the controls in the container and act upon
them.

Making sense?

是的，这很容易。最大的问题是，在回发中，你需要重新创建控件。我刚刚发布了一个样本：

Yep, it''s fairly easy. The big problem is that across postbacks it''s up to
you to recreate the controls. I just posted a sample earlier:
