CreateUserWizard.CreatingUser Event

Occurs before the membership provider is called to create the new Web site user account.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public event LoginCancelEventHandler CreatingUser
<asp:CreateUserWizard OnCreatingUser="LoginCancelEventHandler" />

The CreatingUser event is raised prior to calling the CreateUser method on the membership provider specified in the MembershipProvider property.

Use the CreatingUser event to establish defaults or modify the information entered by the user before passing the information to the membership provider.

For more information about handling events, see Consuming Events.

The following code example uses the CreatingUser event to make the UserName property all lowercase before submitting it to the membership provider specified in the MembershipProvider property.
