Am I understanding how the BasePage is called up?

I am wondering if I fully understand how the Base Page is called up.

I have installed a file BasePage.vb (not the same coding as the book's) in the App_Code folder. I am running a file called test.aspx. It's code behind is

Code:

Partial Class test
    Inherits BasePage

End Class

There is a MasterPage, for which the code behind is:

Code:

 
Partial Class MasterPage
    Inherits System.Web.UI.MasterPage
End Class

Now as I understand Chapter 6, that should mean that running test.aspx will call up the BasePage which will over ride System.Web.UI.Page - is that correct?

In which case, if I get an error "Error parsing attribute 'meta_keywords': Type 'System.Web.UI.Page' does not have a public property named 'meta_keywords'." am I right in deducing that the BasePage has not the coding that includes the public property for 'meta_keywords', and so does not over ride System.Web.UI.Page?.

I am not asking for this one to be solved here - just asking if I have understood the book correctly, and so have made the correct deduction.

I have figured this one out. Quite a mess of errors - now eliminated.

@ Page was incomplete, as was test.vb, which should have been

Code:

Imports System
Imports System.Web.UI
Imports System.Web.UI.HtmlControls
Partial Class test
    Inherits BasePage

End Class

I wonder, though, if those Imports lines are not implicit anyway - will play with that when I get time.

For those who are interested, what I was working on was allowing meta tags.

Glad you figured it out...

I think you'll be happy to hear that in ASP.NET 4 Microsoft is introducing Page.MetaKeywords and Page.MetaDescription:

That looks rather neat - thanks for the link.
