The Web Form Wizardry of ASP.NET 2.0's Wizard Control

When the data a Web application accepts from the user is too much, splitting the entire Web form into multiple logical sections is a desirable solution. To accomplish this in classic ASP or even ASP.NET 1.x, developers used to create a wizard: multiple Web forms each containing a part of the total information. However, this approach often proved complex and time consuming. ASP.NET 2.0 provides a new control called Wizard that allows hassle-free development of such Web forms. This article demonstrates how to use this control in a typical user registration.

Creating a Web Form with Wizard Control

Begin by creating a new Web site in VS.NET 2005. Drag and drop a Wizard control on the default Web form. The Wizard control is represented by a <asp:Wizard> tag in the markup and by a Wizard class in the code. Figure 1 shows the Wizard control in action.

Figure 1: Structure of Wizard Control

On the left-hand side you have a set of navigation links (Account Details, Contact Information, etc.). This region of the Wizard is called a side bar. The area where the actual data entry controls appear is often called a view. At the top you have a header, and at the bottom you have a navigation bar.

Formatting the Wizard Control

The easiest way to apply formatting to the Wizard control is via the "Auto Format" feature. Select the Wizard control and from its smart tag select "Auto format" to open the Auto Format dialog (see Figure 2).

Here you can select a formatting theme that will quickly apply to the Wizard. You, of course, can customize various formatting attributes manually via various "styles" of the control. Figure 3 shows all the available styles.

Adding Wizard Steps

The main job in using the Wizard control is managing Wizard steps, which act as containers for a set of controls. Each step is represented by the <asp:WizardStep> markup tag.

In order to add or remove steps to the Wizard control, select the "Add/Remove WizardSteps..." option from its smart tag (see Figure 4).

This will open "WizardStep Collection Editor" as shown in Figure 5.

Add in all three steps as shown in Figure 5. Set the Title property of each set to Account Details, Contact Information, and Confirmation, respectively. Also, set the ID property of the three steps to step1, step2, and step3, respectively. The ID property identifies a specific wizard step in the code.

Now, let's design the three wizard steps. Go to the Web form designer and click on the "Account Details" step. This will make that step the active step. Design the step as shown in Figure 6.

Figure 6: Designing Account Details WizardStep

The step consists of three Labels, three TextBoxes, and the validator controls attached to them. The TextBoxes accept the user ID and password. Each of the three TextBoxes has a RequiredFieldValidator attached. Additionally, a CompareValidator ensures that the value entered in the password TextBox matches the one in the confirm password TextBox.

Now click on the "Contact Information" step and design it as shown in Figure 7.

Figure 7: Designing Contact Information WizardStep

The "Contact Information" wizard step consists of two Labels, two TextBoxes, and the validator controls attached to them. The TextBoxes accept the user's email address and telephone number. The RequireFieldValidator and RegularExpression validator controls attached to them ensure that the end user enters the correct input. Note how this step automatically displays Previous and Next buttons.

Finally, design the "Confirmation" wizard step as shown in Figure 8:

The Confirmation wizard step simply displays all the pieces of information entered on the previous steps as a confirmation. Note that since this is the last step of the wizard, the Finish button is displayed instead of the Next button.

The following is the complete markup for your Web form:
