Vue Sortable Methods

This section describes methods that control the Sortable UI component.

See Also

beginUpdate()

Prevents the UI component from refreshing until the endUpdate() method is called.

The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Sortable UI component in an application executed on the desktop.

jQuery
JavaScript
DevExpress.ui.dxSortable.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the Sortable properties
    }
});
Angular
TypeScript
import Sortable from "devextreme/ui/sortable";
// ...
export class AppComponent {
    constructor () {
        Sortable.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the Sortable properties
            }
        });
    }
}
Vue
<template>
    <div>
        <DxSortable id="sortable1" />
        <DxSortable id="sortable2" />
    </div>
</template>
<script>
import DxSortable from "devextreme-vue/sortable";
import Sortable from "devextreme/ui/sortable";

Sortable.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the Sortable properties
    }
});

export default {
    components: {
        DxSortable
    }
}
</script>
React
import React, {useEffect} from "react";
import dxSortable from "devextreme/ui/sortable";
import Sortable from "devextreme-react/sortable";

export default function App() {
    useEffect(() => { 
        dxSortable.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the Sortable properties
            }
        })
    });

    return (
        <div>
            <Sortable id="sortable1" />
            <Sortable id="sortable2" />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the Sortable instance.

After calling this method, remove the DOM element associated with the UI component:

JavaScript
$("#mySortable").dxSortable("dispose");
$("#mySortable").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-sortable ...
    *ngIf="condition">
</dx-sortable>
Vue
App.vue
<template>
    <DxSortable ...
        v-if="condition">
    </DxSortable>
</template>

<script>
import DxSortable from 'devextreme-vue/sortable';

export default {
    components: {
        DxSortable
    }
}
</script>
React
App.js
import React from 'react';

import Sortable from 'devextreme-react/sortable';

function DxSortable(props) {
    if (!props.shouldRender) {
        return null;
    }

    return (
        <Sortable ... >    
        </Sortable>
    );
}

class App extends React.Component {
    render() {
        return (
            <DxSortable shouldRender="condition" />
        );
    }
}
export default App;
