Exception Handling Issue with not being able to access the exception

Question

User-2066630380 posted

I've built a custom membershipprovider handling all possible scenarios. One of which is to further deal with manually triggered exceptions. What I can't figure out for some reason is how to access the exception thrown in the OnPasswordChangeError Method. The server.GetLastError() returns a null. and what ever I do I can't get a hold of it.  Or do I need to pass the exception somehow to the OnPasswordError method? The changepassword only returns a bool to trigger the OnPasswordChageError. So I need to be able to access the exceptions here to be able to handle them.

any help as always much appreciated.

// On PasswordChangeEvent

     if (!r.IsMatch(args.Password))
            {
                args.FailureInformation =
                  new Exception("Password must be at least 6 characters long and " +
                                    "contain at least one number and one special character.");
                args.Cancel = true;

   		throw args.FailureInformation;
            }



// OnPasswordErrorEvent

     /// <summary>
        /// Raises the <see cref="E:System.Web.UI.WebControls.ChangePassword.ChangePasswordError"/> event when the user's password is not changed.
        /// </summary>
        /// <param name="e">An <see cref="T:System.EventArgs"/> object that contains the event data.</param>
        protected override void OnChangePasswordError(EventArgs e)
        {
            var evt = new MembershipEvent("Password error", this, 6, this.UserName, this.NewPassword);
            evt.Raise();

           
            var server = HttpContext.Current.Server;
            Exception error = server.GetLastError();
            this.ChangePasswordFailureText = error.ToString();
            
            base.OnChangePasswordError(e);
        }
