FIGURE 20-7 The ChangePassword.aspx form
Forms for Network Administrators
The SkyShark Airlines application provides two forms for business managers, ManageUsers.aspx and ManageDatabases.aspx. The ManageUsers.aspx form is used to add and remove user accounts, and the ManageDatabases.aspx form is used to update databases. I will discuss the design of these two forms in this section.
ManageUsers.aspx
The ManageUsers.aspx form is divided into two sections. One section is used to add user accounts and the other is used to remove user accounts.The controls you need to add to the ManageUsers.aspx form are given in Table 20-5.

TIP
In the ManageUsers.aspx form, items are added to the lstAddRole property by using the ListItem Collection Editor. The ListItem Collection Editor is invoked when you click on the ellipsis button in the Items property.

After you add the controls specified in Table 20-5, the design of the ManageUsers.aspx form is complete and is shown in Figure 20-8.
FIGURE 20-8 The ManageUsers.aspx form
ManageDatabases.aspx
The ManageDatabases.aspx form includes two Button controls used for moving information pertaining to flight departure from the dtReservations table to the
dtDepartedFlights table and from the dtDepartedFlights table to the dtPassen-
gerDetails table. Apart from the first four controls consistent in all forms and mentioned in Table 20-5, I have added two Button controls to the form. These controls are described in Table 20-6.

Forms for Business Managers
SkyShark Airlines provides four forms for business managers: AddFl.aspx, RequestID.aspx, Reports.aspx, and FreqFl.aspx.The design of these forms is discussed in this section.
AddFl.aspx
The AddFl.aspx form is used to add details of any new flights introduced by SkyShark Airlines. The design of the AddFl.aspx form is straightforward. Apart from including the first four controls mentioned in Table 20-5, I have added text boxes and validation controls for the flight number, departure time and place, arrival time and destination, aircraft type, number of seats in the executive and business classes, and the fares of the executive and business class fields. I have also added two buttons for submitting and canceling the form. The design of the AddFl.aspx form is shown in Figure 20-9.

RequestID.aspx
The RequestID.aspx form is used by business managers to request for new user IDs. The controls in the RequestID.aspx form are listed in Table 20-7.

Reports.aspx
The Reports.aspx form is used to generate reports. The form uses a DataGrid control to display reports corresponding to the type of report selected by the business manager. You can assign a DataView control to the DataGrid control so that data can be formatted and displayed in the form. A DataView control, in turn, retrieves data from a DataSet control. You will learn about using the DataGrid control in Chapter 21, “Implementing the Business Logic.”
The controls you need to add to the Reports.aspx page are listed in Table 20-8.

FreqFl.aspx
The FreqFl.aspx form is used to make the frequent fliers program available to passengers. The form is similar to the Reports.aspx form.The FreqFl.aspx form uses the DataGrid control to list users entitled to the frequent fliers program. The design of the FreqFl.aspx form is shown in Figure 20-12.
