Hi Seuthes,

In the Vue ecosystem, the good implementation practices are to use custom validation components to control the data input. The Kendo UI for Vue Native Grid follows the popular development practices. That is why the component doesn't provide built-in data validation and we don't have plans to add such validation. Following the popular practices, we recommend the usage of custom components for handling the data validation when creating or editing records.

Here is the requested documentation article that demonstrates a possible approach for data validation inside the Native Grid. You can check it and let me know if you have any questions about it. 

Regards,
