动态加载的用户控件的 Page_Load 事件不会从处理程序触发。为什么？

我有一个处理程序 (.ashx) 文件，用于处理请求。根据所需输出的类型，我想加载一个用户控件，该控件将以正确的格式呈现数据。

我以为当我创建 MyUC 实例时，它的加载事件会触发，但我想不会。我什至尝试指定我自己的事件处理程序，但这不起作用。

值得注意的是，我可以创建 MyUC 的实例并将资金分配给其 Funds 属性。这是我需要实际使用该资金列表执行操作的加载事件！

这是我的代码，它不起作用。

    private string GenerateList(IEnumerable<Fund> funds)
    {
        string html = "";

        Page page = new Page();

        MyUC myControl = (MyUC)page.LoadControl("MyUC.ascx");

        myControl.Funds = funds;

        myControl.Load += new EventHandler(myControl_Load);

        return html;
    }

谁能告诉我我做错了什么？我该如何修复它？

谢谢

原文

I have a handler (.ashx) file that I'm using to deal with Requests. Depending on the type of output needed, I want to load a user control that will present the data in the correct format.

I thought that when I created the instance of MyUC its load event would fire, but i guess not. I've even tried specifying my own event handler but that doesn't work.

For what it's worth noting, I can create the instance of the MyUC and assign the funds to its Funds property. It's the load event that I need to actually do stuff with that list of funds!

This is the code that i have, which doesn't work.

    private string GenerateList(IEnumerable<Fund> funds)
    {
        string html = "";

        Page page = new Page();

        MyUC myControl = (MyUC)page.LoadControl("MyUC.ascx");

        myControl.Funds = funds;

        myControl.Load += new EventHandler(myControl_Load);

        return html;
    }

Can anyone tell me what I'm doing wrong? How can I go about fixing it?

Thanks
