Hello people.
I am working on a project and I am very new to asp.net.The scenario is:
There is a asp.net dropdownlist on a page. Based on the selection made in the dropdownlist control, another TextBox''s content will change with no post back to the server. This must be done on the client side.
How can I do it? Can anyone guide me to a beginners tutorial?
For kind info...I am using VisualStudio2008 with .net framework 3.5
Any help will be highly appreciated.

推荐答案

这可以通过不同的方式来实现.

1.使用javascript(纯粹是客户端)
2.使用AJAX

在使用客户端脚本 [

This can be achieved in different ways.

1. Using javascript (purely client side)
2. Using AJAX

Take a look at the MSDN article on Working with Client-side Script[^]. Since you are new to asp.net, its worth spending sometime.

Coming to your question, set the onchange attribute in codebehind page as

ddl.Attributes["onchange"] = "javaScriptFunctoChangeTextbox();";

然后在javascript页面中添加javascript.

And you add the javascript in the aspx page.
