How can I use the PostAuthenticateRequest event of Global.asax? I'm following this tutorial and it mentions that I have to use the PostAuthenticateRequest event. When I added the Global.asax event it created two files, the markup and the code-behind file. Here is the content of the code-behind file
using System;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
namespace authentication
{
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
}
protected void Session_Start(object sender, EventArgs e)
{
}
protected void Application_BeginRequest(object sender, EventArgs e)
{
}
protected void Application_AuthenticateRequest(object sender, EventArgs e)
{
}
protected void Application_Error(object sender, EventArgs e)
{
}
protected void Session_End(object sender, EventArgs e)
{
}
protected void Application_End(object sender, EventArgs e)
{
}
}
}
Now when I type the
protected void Application_OnPostAuthenticateRequest(object sender, EventArgs e)
It is successfully called. Now I want to know how is the PostAuthenticateRequest bound to this Application_OnPostAuthenticateRequest method? How can I change the method to some other?
Magic..., a mechanism called Auto Event Wireup, the same reason you can write
in your code-behind and the method will automatically be called when the page loads.
MSDN description for
System.Web.Configuration.PagesSection.AutoEventWireup
property:When
AutoEventWireup
istrue
, handlers are automatically bound to events at run time based on their name and signature. For each event, ASP.NET searches for a method that is named according to the patternPage_eventname()
, such asPage_Load()
orPage_Init()
. ASP.NET first looks for an overload that has the typical event-handler signature (that is, it specifiesObject
andEventArgs
parameters). If an event handler with this signature is not found, ASP.NET looks for an overload that has no parameters. More details in this answer.If you wanted to do it explicitly you would write the following instead
