For each item, Sitecore invokes the item validation rules defined in the item or the standard values item associated with its data template, as well as global validation rules.
For each data template field, Sitecore invokes the validation rules defined in the data template field definition item, as well as the validation rules defined in the data template field type validation rules definition item.
After you stop editing a field value, Sitecore automatically invokes validation rules asynchronously, and then updates the user interface after validation completes.
Validators.UpdateDelay property in web.config controls the length of time between editing activity and the invocation of validators.
Validators.AutomaticUpdate property when set to false would disable automatic validation feature.
Field Level: We can configure validators to be used for validation at the individual field level. For example, required field validator for a single line text field. All field level validators are present at /sitecore/system/Settings/Validation Rules/Field Rules.
Field Type Level: We can configure validators to be used for validation of all occurrences of a particular field type. For example, all occurrences of DropList field type in sitecore tree. All field type level validators are present at /sitecore/system/Settings/Validation Rules/Field Types
Item Level: We can configure validators for individual items in its presentation details. All item level validators are present at /sitecore/system/Settings/Validation Rules/Item Rules
Standard Values Level: Configure validation for all items based on a data template by configuring validation rules in the standard values of that data template.
Global Level: Configure validation that applies to all items.
