Vue SlideOut Methods

This section describes members used to manipulate the widget.

See Also

beginUpdate()

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

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

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

jQuery
JavaScript
DevExpress.ui.dxSlideOut.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the SlideOut options
    }
});
Angular
TypeScript
import SlideOut from "devextreme/ui/slide_out";
// ...
export class AppComponent {
    constructor () {
        SlideOut.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the SlideOut options
            }
        });
    }
}
Vue
<template>
    <div>
        <DxSlideOut id="slideOut1" />
        <DxSlideOut id="slideOut2" />
    </div>
</template>
<script>
import DxSlideOut from "devextreme-vue/slide-out";
import SlideOut from "devextreme/ui/slide_out";

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

export default {
    components: {
        DxSlideOut
    }
}
</script>
React
import React from "react";
import dxSlideOut from "devextreme/ui/slide_out";
import SlideOut from "devextreme-react/slide-out";

class App extends React.Component {
    render () {
        dxSlideOut.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the SlideOut options
            }
        })
        return (
            <div>
                <SlideOut id="slideOut1" />
                <SlideOut id="slideOut2" />
            </div>
        )
    }
}

export default App;

dispose()

Disposes of all the resources allocated to the SlideOut instance.

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

JavaScript
$("#mySlideOut").dxSlideOut("dispose");
$("#mySlideOut").remove();

Use this method only if the widget was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:

Angular
app.component.html
<dx-slide-out ...
    *ngIf="condition">
</dx-slide-out>
Vue
App.vue
<template>
    <DxSlideOut ...
        v-if="condition">
    </DxSlideOut>
</template>

<script>
import DxSlideOut from 'devextreme-vue/slide-out';

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

import SlideOut from 'devextreme-react/slide-out';

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

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

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