What's Page __EVENTARGUMENT?

Tags:

c#

.net

asp.net

vb.net

ajax.net

I saw code like this:

if (this.Request["__EVENTARGUMENT"] == "Flag")
   //DoSomthing...

What does __EVENTARGUMENT mean and are there some parameters like it to access?

It can be set by calls to __doPostBack in the JavaScript on the page.

This article explains it in a bit more detail.
