#region ITabbed Interface Declaration

    public string tabCaption
    {
        //Tab Name
        get { return "MyTab"; }
    }

    public TabContainersList tabContainerType
    {
        // Target Tabber
        get { return TabContainersList.CrmCompany; }
    }

    public string tabId

        // id

ASP.NET html Example Page

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MyTab.ascx.cs" Inherits="MyTab " %>
<asp:LinkButton runat="server" ID="myId"></asp:LinkButton>
<asp:LinkButton runat="server" ID="myCompany"></asp:LinkButton>
<asp:Button runat="server" ID="button" Text="Test Postback" />

When file.cs is created, yuo have to create an heredity to class from ITabber and implement interface as in example

tabCaption - Tag thah will appear on the tab
tabContainerType - Cartel to wich tab is going to be added, you must refer to Numb to implement other cards
tabId - Id del Tab, deve essere univoco, Id of Tab will be unique
tabPosition - Position of tab in the control-

Completing characteristcs, the tab will be completed and loaded in the cartel

There are some other points you must consider. As you can see in the example, in page_load is verified if control is visible: it avoids to initialize if tab is not selected; also precludes access at context that would contain empty issues

The control, infact, matchs his references to Business Objects on wich is loaded the card. Specifically, each page writes in context Id of open BO and it has his access through:(int)GetContextElements("Id");
