Check Value with Custom Rule

You can implement a custom rule attribute by inheriting from the RulePropertyValue<TPropertyValue> class. Here, such a rule is created to check the length of the specified string property. The rule is applied using a specially designed custom rule attribute in code or in the Application Model. The following properties are checked:
- MoreThan5Symbols must consist of more than five symbols;
- NotMoreThanTenSymbols value length must not exceed 10;
This rule is checked when saving an object.

Name

Ascending

Not filtered

More Than 5 Symbols

Not filtered

Not More Than Ten Symbols

Not filtered

Invalid CustomRuleObject

Short

This string is too long

Valid CustomRuleObject

Now the length is enough to pass the rule

10 symbols
