What types of validation controls are provided by ASP.NET?

There are six main types of validation controls:

  RequiredFieldValidator - It checks whether the control have any value. It’s used when you want the control should not be empty.

 RangeValidator - It checks if the value in validated control is in that specific range. Example txtCustomerCode should not be more than eight length.

  CompareValidator - It checks that the value in controls should match some specific value. Example Textbox TxtPi should be equal to 3.14.

  RegularExpressionValidator - When we want the control value should match with a specific regular expression.

  CustomValidator - It is used to define user-defined validation.

  ValidationSummary - It displays summary of all current validation errors.
