Form validation, show error messages at invalid input-fields

It should be possible for NativeScript apps to define validation rules for input-fields and error-messages, that are shown, if the specific input-field contains non-valid information (and the user jumps to the next input-field).

The validator should return true, if there are no invalid fields, so that the data can be sent to a server for example.

A DataForm-component was planned for 'Telerik UI for NativeScript', but there are no updates since February.
