Please advice .Thanks in advance
推荐答案
如Kirtan所述，最简单的答案是以使用更新面板.
As Kirtan mentioned, the easiest answer is to use an Update Panel.
如果您不想走那条路，那么可以使用jQuery对IHttpHandler进行Ajax调用，该IHttpHandler返回您需要填充要更新的面板的数据.
If you don't want to go that route, then you can use jQuery to make Ajax calls to an IHttpHandler which returns the data you need to populate the panel you want to update.
步骤如下:
- 使用jQuery调用"
.ashx" Ajax处理程序. - 让您的"
.ashx"文件以您选择的格式生成响应.可以是JSON或XML(如果您想让JavaScript解析响应并生成列表)，或者可以将HTML内容本身添加到页面中. - jQuery将收到您的处理程序的响应，并使用适当的数据填充面板.
- Use jQuery to call "
.ashx" Ajax handler. - Have your "
.ashx" file generate a response in your format of choice. This could be JSON or XML (if you want JavaScript to parse out the response and generate the list), or the HTML content itself to be added to the page. - jQuery will receive the response from your handler, and populate your panel with the appropriate data.
在线上有一些有关如何使用IHttpHander的教程.基本上，这是从ASP.NET的"Page"类派生的非常简单的接口.它的重量比Page类的重量轻得多，因此与UpdatePanel相比，您可以获得更好的性能，但是，与大多数性能提升技术一样，您的代码也稍微复杂一些.
There are a few tutorials online about how to use an IHttpHander. Basically it's a very simple interface that ASP.NET's "Page" class is derived from. It is much lighter weight than the Page class so you can get better performance than you would from an UpdatePanel, however, as with most performance boosting techniques, you have slightly more complex code.
