如何使用jQuery和AJAX刷新ASP.NET ListView？ [英] How do I refresh an ASP.NET ListView using jQuery and AJAX?

问题描述

我有一个页面与一些ListViews，我希望用户能够排序和浏览。而不是每次回发和重新绑定整个页面，我想通过jQuery / AJAX有选择地为有问题的控件执行。我很乐意让客户端调用我的页面中的WebMethod - 我的问题是如何通过jQuery将返回的数据返回到ListView？

（注意：我不想使用UpdatePanel！）

解决方案

我不知道是否真的可以实现更新ListView没有回发，只是因为ListView控件的底层数据模型。

最好的选择是使用一个完整的AJAX解决方案来使用JavaScript模板引擎。我使用jTemplates和MS AJAX Library v4预览在我的博客上做了一个演示 - http://www.aaron-powell.com/blog.aspx?id=1209

但尽管有相当的信念，您可以使用UpdatePanel并使其有效，我也在这里查看： http ：//www.aaron-powell.com/blog.aspx？id = 1195 。使用UpdatePanels时要记住的最大的事情是ViewState。如果您不需要在控件上保存ViewState，请确保已关闭。你可以通过这样做减少你的后期负载。还要清除空格将有所帮助。

I have a page with a number of ListViews that I want users to be able to sort and page through. Rather than postback and rebind the entire page each time, I would like to do it via jQuery/AJAX selectively for the control in question. I am comfortable making the client-side call to a WebMethod in my page - my question is how do I get the returned data back into the ListView via jQuery?

(Note: I don't want to use an UpdatePanel!)

解决方案

I'm not sure if it'll actually be achievable to update a ListView without a postback, just because of the underlying data model of the ListView control.

You're best option to having a complete AJAX solution would be to use a JavaScript templating engine. I've done a demo on my blog using jTemplates and the MS AJAX Library v4 preview - http://www.aaron-powell.com/blog.aspx?id=1209

But despite common belief you can use an UpdatePanel and have it efficient, I also looked at that here: http://www.aaron-powell.com/blog.aspx?id=1195. The biggest thing to keep in mind when using UpdatePanels is ViewState. If you don't need ViewState saved on a control make sure it's turned off. You can really reduce your post-load by doing that. Also removing whitespace will help.
