I'm not sure what you mean here. If you want to set some values inside of
your custom page class, you can add public properties to the custom page
class. You can then create a separate control which has mirror copies of
those properties, and which simply sets them in the custom page class:

<wc:MyControl PageID="p1" PageCategory="Company"
PageSubCategory="Investment" />

MyControl would save the property values in class members until OnLoad is
called, then:

protected override void OnLoad(EventArgs e)
{
MyPage p = this.Page as MyPage;
if (p == null)
return;

p.PageID = m_PageID;
p.PageCategory = m_PageCategory;
p.PageSubCategory = m_PageSubCategory;

base.OnLoad(e);
}

....
The problem seems that Im using Overload that cuases only One of the OnInits
To Fire

When you override a method, you should almost always call the base class
method. When you call it depends on the nature of the method, but in this
case, call base.OnInit(e) at the end of your OnInit override.

Imports System.Web

Imports System.Web.UI

Imports System.Data

Namespace MTT.PageClasses

Public Class GenericPage

Inherits System.Web.UI.Page

Protected Overrides Sub OnInit(ByVal e As System.EventArgs)

Dim myCtrl As Control

For Each myCtrl In Page.Controls

Response.Write(myCtrl.ID)

Next



End Sub

End Class

End Namespace


Also another question is it possible to Inherit The page class more than
once
I want a GenericPageClass That Does Some Work on OnInit

I want Another MainPageClass That Inherits Generic Page Class And i want to
do some work OnInit Int this sub
The problem seems that Im using Overload that cuases only One of the OnInits
To Fire

Is there a way i can get these 2 OnInit Subs Perform Different to the one
page

Thanks
