Occurs when the control switches to a new step (either because the user has clicked a navigation button or your code has changed the ActiveStepIndex property). Occurs when the Cancel button is clicked. The cancel button is not shown by default, but you can add it to every step by setting the Wizard.DisplayCancelButton property. Usually, a cancel button exits the wizard. If you don t have any cleanup code to perform, just set the CancelDestinationPageUrl property, and the wizard will take care of the redirection automatically. Occurs when the Finish button is clicked. Occurs when the Next or Previous button is clicked on any step. However, because there is more than one way to move from one step to the next, it s better to handle the ActiveStepChanged event. Occurs when a button in the sidebar area is clicked.

URL authorization gives you the ability to allow or deny access to certain directories for individual users or roles. ASP.NET uses the IPrincipal object in the HttpContext to run identity and role checks for URL authorization, so you can define access permissions based on Windows accounts if you re using Windows Authentication or non-Windows accounts if you re using Forms Authentication. If an incoming request does not pass URL authorization, and the application is using Windows Authentication, then ASP.NET generates a 401 Unauthorized HTTP error and returns it to the client. If the application is configured for Forms Authentication, then ASP.NET redirects the user to the login page specified in Web.config.

On the whole, two wizard programming models exist: Commit-as-you-go: This makes sense if each wizard step wraps an atomic operation that can t be reversed. For example, if you re processing an order that involves a credit card authorization followed by a final purchase, you can t allow the user to step back and edit the credit card number. To support this model, you set the AllowReturn property to false on some or all steps, and you respond to the ActiveStepChanged event to commit changes for each step. Commit-at-the-end: This makes sense if each wizard step is collecting information for an operation that s performed only at the end. For example, if you re collecting user information and plan to generate a new account once you have all the information, you ll probably allow a user to make changes midway through the process. You execute your code for generating the new account when the wizard is finished by reacting to the FinishButtonClick event.

To implement commit-at-the-end with the current example, just respond to the FinishButtonClick event. Here s an example that simply displays every selection in the summary: protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { StringBuilder sb = new StringBuilder(); sb.Append("<b>You chose: <br />"); sb.Append("Programming Language: "); sb.Append(lstLanguage.Text); sb.Append("<br />Total Employees: "); sb.Append(txtEmpCount.Text); sb.Append("<br />Total Locations: "); sb.Append(txtLocCount.Text); sb.Append("<br />Licenses Required: "); foreach (ListItem item in lstTools.Items) { if (item.Selected) { sb.Append(item.Text); sb.Append(" "); } } sb.Append("</b>"); lblSummary.Text = sb.ToString(); } For this to work, you must add a Label control named lblSummary to the summary step.

Configuring your ASP.NET application to use Windows Authentication (via Web.config) enables the file authorization module. The file authorization module checks the NTFS file permissions to determine whether or not the authenticated user has access to the requested resource. NTFS permission checks are normally performed using the access token of the thread requesting the file. When impersonation is disabled, however, the thread processing the request runs under the security context of the ASPNET/Network Service account for every single user, making it impossible to enforce user-level permissions on requested files. The file authorization module alleviates this issue by using the access token generated by IIS to check NTFS file permissions on the requested file. The IIS token is always representative of the authenticated user, even when impersonation is disabled, making it possible to enforce userlevel file permissions. Why not just enable impersonation There may be performance issues with database connection pooling that arise when using integrated SQL Server security and user-level impersonation. Thus, the file authorization module allows you the benefit of user-level NTFS permission checking without the performance issues associated with user-level impersonation.
