What’s the difference between customvalidator and validation control?
The CustomValidator control is a separate control from the input control it validates, which allows you to control where the validation message is displayed. Validation controls always perform validation on the server.
When to use a requiredvalidator in webcontrols?
If the input control is empty, no validation functions are called and validation succeeds. Use a RequiredFieldValidator control to require the user to enter data in the input control. It is possible to use a CustomValidator control without setting the ControlToValidate property.

Note that the custom validation subroutine is not called when the control being validated does not contain any data. We have used the RequiredFieldValidator control to check for an empty form field.
How are data validation rules built into Excel?

How to create validation rules for Business Objects?
To define validation rules and object functions, you can use a code editor to write your Groovy scripts. To create triggers, you use the trigger designer, a visual editor for creating sequences that execute actions on your business objects.

This means that unless the user modifies the fields to match the criteria, they won’t be able to go through verification when a new record is created or when changes on an existing one are trying to be saved.
What are the different validation rules in Salesforce?

Instead, let’s change the message so it returns “’Pets’ must contain fewer than 10 items.”
When to use predicate validator in custom validation?
The recommended way is to make use of the Predicate Validator to write a custom validation function, but you can also use the Custom method to take full control of the validation process. For these examples, we’ll imagine a scenario where you want to create a reusable validator that will ensure a List object contains fewer than 10 items.
How to use custom validator in fluent validation?
