Question

我对JavaScript有些新意。我正在使用一个名为Spread的网格控件，在该网格中我有三行和三列组合框。我还有一个原生的ASP文本框。我想要的是在文本框中显示组合框的值，一旦客户端更改了它。为此，我正在使用Spread控件的DataChanged事件。但是，当我在本地运行并更改任何Spread的组合框中的值时，没有任何反应。

这是我的代码：

Answer 1

ASP.NET服务器控件ID不是客户端（javascript）ID。

关于事件和一切。

所有FarPoint:FpSpread处理都应该在C＃（或VB？）代码隐藏中进行。

可以在JS中处理某些事件，但服务器控件应该以某种方式支持它。

详细了解asp.net controls

事件没有在JavaScript中触发
