ASP.net下拉列表按需加载

I was wondering if anyone know or come across any tutorial or howto on loading data to the dropdownlist on demand like the rad control by telerik where you can initially load say 10 items to the dropdownlist control then at the very bottom of the dropdown there is a continue or load the next 10 items, click on it then the control will load the next 10 items...etc.

我想知道是否有人知道或遇到任何教程或如何根据需要将数据加载到下拉列表,如telerik的rad控制,您可以在最初将10个项目加载到下拉列表控件,然后在下拉列表的最底部有一个继续或加载接下来的10个项目,点击它然后控件将加载接下来的10个项目......等等。

You should be able to use the AJAX control toolkit - especially the CascadingDropDown Sample. I am sure you could customize the handler to limit the return set and expand on demand.

您应该能够使用AJAX控件工具包 - 尤其是CascadingDropDown示例。我相信您可以自定义处理程序以限制返回集并按需扩展。
