I had to validate the login page of my app. It had only two textbox es (UserId,Password) and a login button on the page. There are quite a few validations I can think ofand some of them were duplicate for both boxes , whereas some validations include both boxes in their critera.I started think as to which controls I can drop to do the work fast.I decided to to use the combination of RequiredFiedValidator,Custo... and VaidationSummary. There cam a few problems ** I could not use javascript...
