JavaScript/jQuery ActionSheet Methods

This section describes the members used to manipulate the 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 ActionSheet UI component in an application executed on the desktop.

jQuery
JavaScript
DevExpress.ui.dxActionSheet.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the ActionSheet options
    }
});
Angular
TypeScript
import ActionSheet from "devextreme/ui/action_sheet";
// ...
export class AppComponent {
    constructor () {
        ActionSheet.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the ActionSheet options
            }
        });
    }
}
Vue
<template>
    <div>
        <DxActionSheet id="actionSheet1" />
        <DxActionSheet id="actionSheet2" />
    </div>
</template>
<script>
import DxActionSheet from "devextreme-vue/action-sheet";
import ActionSheet from "devextreme/ui/action_sheet";

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

export default {
    components: {
        DxActionSheet
    }
}
</script>
React
import React from "react";
import dxActionSheet from "devextreme/ui/action_sheet";
import ActionSheet from "devextreme-react/action-sheet";

class App extends React.Component {
    render () {
        dxActionSheet.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the ActionSheet options
            }
        })
        return (
            <div>
                <ActionSheet id="actionSheet1" />
                <ActionSheet id="actionSheet2" />
            </div>
        )
    }
}

export default App;

dispose()

Disposes of all the resources allocated to the ActionSheet instance.

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

JavaScript
$("#myActionSheet").dxActionSheet("dispose");
$("#myActionSheet").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-action-sheet ...
    *ngIf="condition">
</dx-action-sheet>
Vue
App.vue
<template>
    <DxActionSheet ...
        v-if="condition">
    </DxActionSheet>
</template>

<script>
import DxActionSheet from 'devextreme-vue/action-sheet';

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

import ActionSheet from 'devextreme-react/action-sheet';

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

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

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

...
let element = document.getElementById("myActionSheet");
