Is there Page_PreInit, but for the entire application?

[Edward]

Hi All,

Would anyone know if there is an event similar to the Page_PreInit that I
can code just once, at a global initialization level, that applies to all
pages executed?

Therefore, instead of placing the code below in every page codebehind, I
could code it just once.
Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.PreInit

If Not Request.Browser.Browser.Contains("IE") Then

Me.ClientTarget = "uplevel"

End If

End Sub


Thanks

There isn't.

Two main options:

1) Use MasterPages and ContentPages. However, since MasterPages don't have a
Page_PreInit event, you would need to create a base class which inherited
the Page object, create a Page_PreInit event in that, and then have your
MasterPages inherit the base class.

2) Do the above but without MasterPages i.e. create a base class with the
Page_PreInit code, and derive all your other pages from it.

The master page solution is a good one.

an HttpModule's BeginRequest might also do the trick (or you could just use
Global.asax's).

That's the one I use.

Here's an article which describes this, albeit for a different purpose...

Interestingly enough, I've never actually got this to work properly - IIRC,
although the BeginRequest method does indeed fire before the PreInit method,
I never seemed to get access to the Page object at this stage...

There isn't one.
The good news is that you can build an httpmodule which will do the job for you.

See :

Brock uses it to select a Theme, but you can modify the code to do what you want to do.

His sample code is at :
http://staff.develop.com/ballen/blo...lop.com/ballen/samples/DynamicThemeSample.zip

....but read his blog entry before attempting to use it.

I sent in a suggestion before I read both of yours, which also do the work.

Brock's sample HttpModule code also works...

I believe you...

great! ... so many options to digest!

thanks everyone for your contribution
