What might be happening is that in order to import a namespace, it needs to be the fully qualified namespace including the application namespace in order to be recognized.  Use the Intellisense in VS.NET to help with finding the namespace.  The following code sample does work without error:

1st, the class:

Namespace One

    Public Class Class1

        Public Function MyFunction() As String

            Return "Adding Inventory via MyMethod!"

        End Function

    End Class

End Namespace

And 2nd, a sample .aspx with an Imports to that namespace 'One' fully qualified starting with the application name:

'Imports the Namespace 'One'
Imports MyInventoryAppName.One

Partial Public Class WebForm1
    Inherits System.Web.UI.Page

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

    End Sub

End Class

Hope this helps!

imports project1.One

 

When you typed 'project1.' did the Intellisense show the 'One' namespace, or did you just manually type that line?  If it did not show it, then use Intellisense to drill down to the proper namespace, and do not try and guess it.

Also, these assumtions are made in that your class file is in the same project in which you are referencing it from (by metioning it is in the app_code folder).  If this class is part of a separate project and compiled on its own into a .dll, you need to add a reference to it from the 'Project References' before you will be able to use it.

Can you scroll through the namepsapces and see any other project namespace or class name that is required?

or let me know step by step things fr creating a namespace a7 calling it in the page

Usually at this point I recommend the following: since it appears you are pretty new to .NET, I recommend creating a brand new project and using the tested code I provided in my earlier post and get that working.  At least this way you can see how namespaces work, and how it does work properly.  Then once you get it working, then you can go back to your existing project and determine the issue.  Based on your brief descriptions, I do not know the exact issue.  If you want you can post all of the code, but I still think using the test code I provided to get things working is a better option.
