Validation controls in ASP.NET AJAX 4.0

Question

Explain about several validation controls which are available in ASP.NET AJAX 4.0?

Answer 1

a) FilteredTextBoxExtender – It allows you to apply filtering to a text box.

b) MaskedEditExtender and MaskedEditValidator – It restricts a user to enter only certain pattern of the characters in TextBox by applying a mask to the input.

c) ValidatorCalloutExtender – It attaches to the ASP.NET validators so that error messages are not displayed as simple text but as a balloon-style ToolTip.

d) NoBot – It prevents the spam/bot from filling the input forms automatically and uses the Completely Automated Public Turing test to tell the Computers and Humans Apart (CAPTCHA), that is a type of challenge-response test to confirm that the response is not generated by the computer.

e) PasswordStrengthExtender – This measures strength of the password text entered within the text box by validating the different strength specified parameters.
