What are few properties and methods that are common to all validation controls ?

The important properties and methods common to all validation controls are as follows:

1. ControlToValidate - Specifies which control to be validated
2. IsValid - Boolean value stating whether control to be validated is valid or not
3. ErrorMessage - Error message which will be displayed in Validation Summary
4. Validate - Method to validate and set IsValid property
5. Display - This specifies how the error message is shown.

Possible display options are :

• None (The validation message is never displayed.)
• Static (Space for the validation message is allocated in the page layout.)
• Dynamic (Space for the validation message is dynamically added to the page if validation fails.)
