Bring up a project. Put a button in the HTML page that says Join Classes below the line beginning with <form id=..... So, we'll have two different classes and then we'll join them together, produce some results, and then display them. That's the objective here:
<asp:Button ID="Button1" runat="server" Text="Join Classes" />
Next, switch to the Design view and double-click on the Join Classes button. This takes us into Default.aspx.cs. Delete the Page_Load block. The relevant portion of the starting code for this project should look like Figure 15.10.1:
