在ASP.NET，C#中选中复选框时显示文本框 [英] Display TextBox when Checkbox Checked in ASP.NET,C#

问题描述

亲爱的所有人，

我正在研究调查项目. (ASP.Net，C#，SQLSERVER 2005)

我在网络表单上有15个带有是"或否"单选按钮的问题.单击提交按钮后，其工作正常并存储在数据库中.

现在，除了那个单选按钮，我还有一个复选框和TEXTBOX.

当我选中(勾号)复选框时，应显示该文本框，并且用户应在文本框中输入评论，然后他应提交评论.


注意:如果用户选中了CHECKBOX ....，则TEXTBOX必须显示在该复选框旁边....如果不显示，则为
.
请问有人可以为此提供解决方案吗?

非常感谢.

使用此i:

使复选框自动回发属性为True.和文本框visible = false


然后双击复选框:

Use this i:

Make Checkbox Autopostback Property True. and textbox visible=false


Then Double click on Checkbox :

if(chk.checked)
{
  textbox.visible=true;
}
else
{
  textbox.visible=false;
}
