Custom Attribute in ASP.NET for Page_Load

Question

Hi, I have an ASP.NET 3.5 Site where, in some places, I am checking if the currently logged on Active Directory user is in a certain AD Security Group. In the Page_Load I'm doing something like this:

if (isInADGroup(UserGUID))

{ //proceed }

Now I was wondering, couldn't I just create a Custom Attribute, like some of MVC's security attributes, which runs this check and cancels the execution or displays an error message?

Not sure about an attribute but you could always create a custom page that handles this inheriting from System.Web.UI.Page and use this as the base class for your web forms.
