插入动态复选框 [英] Inserting dynamic checkbox

问题描述

你好，

我正在开发一个项目，当用户检查页面上的现有复选框时，我必须在其中动态插入复选框列表.
我尝试执行此操作，但如果用户选择现有复选框即chk1
，则它不起作用
我的.cs页面

推荐答案

请参考:
如何使用C#在ASP.Net中生成动态复选框 [

Please refer:
How to generate Dynamic Checkbox in ASP.Net using C#[^]

And more imp. make auto post back property True of your check box.

将auto postback = true用于现有复选框

use auto postback =true for existing checkbox

在复选框属性中添加AutoPostBack ="true".像这样

add AutoPostBack="true" in check box attribute. Like this

<asp:checkbox id="chk1" runat="server" text="hai" oncheckedchanged="chk1_CheckedChanged" autopostback="true" xmlns:asp="#unknown" />
