Angular ValidationGroup Methods
dispose()
Use conditional rendering instead of this method:
- <dx-validation-group ...
- *ngIf="condition">
- </dx-validation-group>
getInstance(element)
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);
