dispose()
The following code disposes of an ValidationGroup instance that corresponds to the element ID (or reference variable in Angular) and removes the element from the DOM:
jQuery
$("#myValidationGroup").dxValidationGroup("dispose"); $("#myValidationGroup").remove();
Angular
<dx-validation-group #validationGroupVar id="myValidationGroup"></dx-validation-group>
import { ..., ViewChild } from "@angular/core"; import { DxValidationGroupComponent } from "devextreme-angular"; // ... export class AppComponent { @ViewChild("validationGroupVar") validationGroup: DxValidationGroupComponent; removeValidationGroup (e) { this.validationGroup.instance.dispose(); document.getElementById("myValidationGroup").remove(); } }
getInstance(element)
getInstance is a static method that the widget 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);
