Methods
dispose()
After calling this method, remove the DOM element associated with the UI component:
JavaScript
$("#myValidationGroup").dxValidationGroup("dispose");
$("#myValidationGroup").remove();Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
app.component.html
<dx-validation-group ...
*ngIf="condition">
</dx-validation-group>Vue
App.vue
<template>
<DxValidationGroup ...
v-if="condition">
</DxValidationGroup>
</template>
<script>
import DxValidationGroup from 'devextreme-vue/validation-group';
export default {
components: {
DxValidationGroup
}
}
</script>React
App.js
import React from 'react';
import ValidationGroup from 'devextreme-react/validation-group';
function DxValidationGroup(props) {
if (!props.shouldRender) {
return null;
}
return (
<ValidationGroup ... >
</ValidationGroup>
);
}
class App extends React.Component {
render() {
return (
<DxValidationGroup shouldRender="condition" />
);
}
}

getInstance(element)
Return Value:
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
reset()
Resets the value and validation result of the editors that are included to the current validation group.
validate()
Validates rules of the validators that belong to the current validation group.
