The default value for AutoEventWireup is true for a C# web
form, and false for a VB.NET web form. The IDE adds the
default values to the @ Page directive for a new web form.
The difference in defaults is partly because VB.NET has a
mechanism for defining an event handler and subscribing to
an event in one graceful motion (the Handles keyword).


Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles Me.Load
' ...

End Sub


An easy way to generate the above code is to use the drop
down controls that sit just above the editor. Note: C#
doesn t make the dropdown list of events available when
editing a code-beside file, but the dropdown is available
when writing in-line code.

There is no equivalent to the Handles keyword in C#
(anonymous event handlers are arguably close, but just not
the same). When AutoEventWireup is true, all we need to do
is follow the method naming convention of
Page_EventToHandle. The ASP.NET runtime will automatically
find and fire the method for the appropriate event.


protected void Page_Load(object sender, EventArgs e)
{

}


Once Again, In Reverse
If we switch to AutoEventWireup= true for a VB.NET web
form, we can use the magic Page_EventName approach. The
only change to the earlier VB.NET code would be to drop the
Handles clause, and the events fire correctly.

If we switch to AutoEventWireup= false for a C# web form,
there is a little extra work to do. Somewhere we need to
explicitly wire up events. Here is one approach.


public partial class _Default : Page
{
public _Default() // ctor
{
Load += new EventHandler(Page_Load);
PreInit += new EventHandler(Page_PreInit);
}

protected void Page_Load(object sender, EventArgs e)
{
// ...
}

protected void Page_PreInit(object sender, EventArgs e)
{
// ...
}
}
