getInstance is a static method that the UI component class supports. The following code demonstrates how to get the ValidationGroup instance found in an element with the myValidationGroup ID:
// Modular approach
import ValidationGroup from "devextreme/ui/validation_group";
...
let element = document.getElementById("myValidationGroup");
let instance = ValidationGroup.getInstance(element) as ValidationGroup;
// Non-modular approach
let element = document.getElementById("myValidationGroup");
let instance = DevExpress.ui.dxValidationGroup.getInstance(element);See Also
