We will know how to do login page using login control. Drag and drop a login control to a webpage and in Login1_Authenticate write the code as shown below to validate the user. If the user enters valid credentials then the control moves to Home.aspx page. If we enter wrong username and password it will display your login attempt was not successful. Please try again.
