ChangePassword Constructor
Initializes a new instance of the ChangePassword class.
Assembly: System.Web (in System.Web.dll)
The following code example shows how to set the NewPasswordRegularExpression property to define a regular expression that checks passwords to ensure that they meet the following criteria:
Are greater than six characters.
Contain at least one digit.
Contain at least one special (non-alphanumeric) character.
The password requirements contained in the PasswordHintText property are displayed to the user.
If the password entered by the user does not meet the criteria, the text contained in the NewPasswordRegularExpressionErrorMessage property is displayed to the user. If a new password is not entered, the text contained in the NewPasswordRequiredErrorMessage property is displayed to the user.
Note: |
|---|
The new password must meet the minimum requirements set by the membership provider in the MinRequiredPasswordLength, MinRequiredNonAlphanumericCharacters, and PasswordStrengthRegularExpression properties. If the password does not meet these requirements, the ChangePasswordError event is raised. |
