Hello Chetan,

I am afraid there is no way how to make the form field unique with out of the box functionality in Kentico. You would need to create a custom form control or modify the existing ones to achieve it.

Documentation for developing custom form controls can be found here - Developing form controls.

Your custom validation should be performed in the IsValid() method where you can also specify the custom error message.

Best regards,

Chetan Sharma,

Here is some workarounds comes to my mind depending on what you want to achieve:

If you want to just show a message whenever user entered an existing field data you may use General Condition validation rules on the field which allows you to define a Macro rule and I think with a macro method you can check if the value exist or not. I have never test it but may it worse to give it a go!

But if you want to generate a unique value while adding a record, you may use default value macros and generate for example add to max of that field.
