的Page_Load [英] Page_Load

问题描述

嗨。


我在网络表单上有一个名为btnSelect的按钮。它有一个处理程序。

然而，在调用处理程序之前调用Page_Load（）。


我想要执行以下操作。在Page_Load（）中，我想检查

btnSelect是否导致了该事件。我该怎么办？


请帮忙。

很酷！

解决方案

看看Request对象中可用的值;你应该能够找到你需要的信息，因为所有信息都是通过

POST提交的表格发送的。


但是，我不确定这是正确的做法。相反，你应该在一个子程序中隔离相关代码并从btnSelect

事件中调用它。

是。你对帖子的表单提交是正确的。我可以获得

的信息。然而，这是一个不同的故事。


这与回发和捕获事件有关。


问题是，我如何检查导致此事件的对象是什么？

来到Page_Load（）？"。


请帮助。

Hi.

I have a button called btnSelect on a web form. There is a handler for it.
However, the Page_Load() gets called before the handler gets called.

I want to do the following. In the Page_Load(), I want to check if the
btnSelect caused the event. How can I do this?

Please help.

解决方案

Take a look at the values available int Request object; you should be able
to find the information you need because all the information send by the
POST submission of the form is there.

However, I''m not sure is this is the right thing to do. Instead, you should
isolate the relevant code in a subroutine and call it from the btnSelect
event.

Yes. You are right about the form submission with the post. I can get the
information. However, this is a little different story.

This has more to do with postback and capturing events.

The question is, "How do I check what object caused this event for it to
come to Page_Load()?".

Please help.
