我试着去寻找使用Ajax来加载用户控件的最佳做法。

Im trying to find a best practice to load usercontrols using Ajax.

在这里简单地用一个UpdatePanel和LoadControl（）对阿贾克斯回发popuplating，但这样会重新呈现在同一个UpdatePanel的其他加载的用户控件我的第一种方法。我也不能有，因为用户控件我需要加载将改变数predefined设置的UpdatePanel的。

My first approach where simply using an UpdatePanel and popuplating it with LoadControl() on ajax postbacks but this would rerender other loaded usercontrols in the same UpdatePanel. Also I cannot have a predefined set of UpdatePanels since the number of UserControls I need to load will vary.

是否有此类情况的任何最佳实践？

Is there any best practice for this type of scenario?

如果需要，我可以实现一个框架或某种类型的自定义控件，如果这将是一个解决方案，但我很乐意与ASP.NET 3.5和AjaxControlToolkit中的如果可能做到这一点。

If needed I could implement a framework or some type of custom controls if that would be a solution but I would love to do this with ASP.NET 3.5 and the AjaxControlToolkit if possible.

大概几十达官显贵的原因不是做这种方式，而只是initalizing一个页面，添加用户控件，然后执行并转储生成的HTML无论它可以理所当然你，是（在我头脑简单的观点），所以心态麻木快速和放大器;我只是有乐趣就别提了......

Probably dozens of high-brow reasons for not doing it this way, but simply initalizing a page, adding the usercontrol, then executing and dump the resulting HTML wherever it may behoove you, is (in my simpleminded view) so mind-numbingly fast & fun that I just have to mention it...

跳过的UpdatePanel，只使用一个标签，一个普通的旧跨度，或者怎么样的缩写...

Skip the UpdatePanels, just use a Label, a plain old span, or how about an acronym...

在客户端使用jQuery：

Using JQuery on the client side:

$('#SomeContainer').Load("default.aspx?What=GimmeSomeSweetAjax");

服务器端：

if(Request.QueryString["What"]==GimmeSomeSweetAjax)
{
   Page page = new Page();
   Control control = (Control)LoadControl("~/.../someUC.ascx");
   StringWriter sw = new StringWriter();
   page.Controls.Add(control);
   Server.Execute(page, sw, false);
   Response.Write(sw.ToString());
   Response.Flush();
   Response.Close();
}

闲来无事执行，并在页面的生命周期有一个真正的苏珊时刻; - ）

Nothing else executes, and the page's lifecycle has a real Kevorkian moment ;-)
