Vue DateRangeBox Methods

This section describes members used to configure the DateRangeBox UI component.

See Also

beginUpdate()

Postpones rendering that can negatively affect performance until the endUpdate() method is called.

The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.

See Also

blur()

Removes focus from the input element.

See Also

close()

Closes the drop-down editor.

See Also

content()

Gets the popup window's content.

Return Value:

HTMLElement | jQuery

An HTML element or a jQuery element when you use jQuery.

See Also

defaultOptions(rule)

Specifies the device-dependent default configuration properties for this component.

Parameters:
rule:

Object

The component's default device properties.

Object structure:
Name Type Description
device

Device

|

Function

Device parameters.
When you specify a function, get information about the current device from the argument. Return true if the properties should be applied to the device.

options

Object

Options to be applied.

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 DateRangeBox UI component in an application executed on the desktop.

jQuery
JavaScript
DevExpress.ui.dxDateRangeBox.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the DateRangeBox properties
    }
});
Angular
TypeScript
import DateRangeBox, { Properties } from "devextreme/ui/date_range_box";
// ...
export class AppComponent {
    constructor () {
        DateRangeBox.defaultOptions<Properties>({
            device: { deviceType: "desktop" },
            options: {
                // Here go the DateRangeBox properties
            }
        });
    }
}
Vue
<template>
    <div>
        <DxDateRangeBox id="dateRangeBox1" />
        <DxDateRangeBox id="dateRangeBox2" />
    </div>
</template>
<script>
import DxDateRangeBox from "devextreme-vue/date-range-box";
import DateRangeBox from "devextreme/ui/date_range_box";

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

export default {
    components: {
        DxDateRangeBox
    }
}
</script>
React
import dxDateRangeBox from "devextreme/ui/date_range_box";
import DateRangeBox from "devextreme-react/date-range-box";

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

export default function App() {
    return (
        <div>
            <DateRangeBox id="dateRangeBox1" />
            <DateRangeBox id="dateRangeBox2" />
        </div>
    )
}

You can also set rules for multiple device types:

jQuery
JavaScript
const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    DevExpress.ui.dxDateRangeBox.defaultOptions({ 
        device: deviceConfig,
        options: {
            // Here go the DateRangeBox properties
        }
    });
});
Angular
TypeScript
import DateRangeBox, { Properties } from "devextreme/ui/date_range_box";
// ...
export class AppComponent {
    constructor () {
        const devicesConfig = [
            { deviceType: 'desktop' },
            { deviceType: 'tablet' },
            { deviceType: 'phone' },
        ];

        devicesConfig.forEach(deviceConfig => {
            DateRangeBox.defaultOptions<Properties>({
                device: deviceConfig,
                options: {
                    // Here go the DateRangeBox properties
                }
            });
        });
    }
}
Vue
<template>
    <div>
        <DxDateRangeBox />
    </div>
</template>
<script>
import DxDateRangeBox from "devextreme-vue/date-range-box";
import DateRangeBox from "devextreme/ui/date_range_box";

const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    DateRangeBox.defaultOptions({
        device: deviceConfig,
        options: {
            // Here go the DateRangeBox properties
        }
    });
});

export default {
    components: {
        DxDateRangeBox
    }
}
</script>
React
import dxDateRangeBox from "devextreme/ui/date_range_box";
import DateRangeBox from "devextreme-react/date-range-box";

const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    dxDateRangeBox.defaultOptions({
        device: deviceConfig,
        options: {
            // Here go the DateRangeBox properties
        }
    });
});

export default function App() {
    return (
        <div>
            <DateRangeBox />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the DateRangeBox instance.

jQuery

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

JavaScript
$("#myDateRangeBox").dxDateRangeBox("dispose");
$("#myDateRangeBox").remove();
Angular

Use conditional rendering instead of this method:

app.component.html
<dx-date-range-box ...
    *ngIf="condition">
</dx-date-range-box>
Vue

Use conditional rendering instead of this method:

App.vue
<template>
    <DxDateRangeBox ...
        v-if="condition">
    </DxDateRangeBox>
</template>

<script>
import DxDateRangeBox from 'devextreme-vue/date-range-box';

export default {
    components: {
        DxDateRangeBox
    }
}
</script>
React

Use conditional rendering instead of this method:

App.js
import React from 'react';

import DateRangeBox from 'devextreme-react/date-range-box';

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

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

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

element()

Gets the root UI component element.

Return Value:

HTMLElement | jQuery

An HTML element or a jQuery element when you use jQuery.

See Also

endDateField()

Gets the <input> element of the UI component's end date field.

Return Value:

HTMLElement | jQuery

An HTML element or a jQuery element when you use jQuery.

See Also

endUpdate()

Refreshes the UI component after a call of the beginUpdate() method.

The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.

See Also

focus()

Sets focus to the input element representing the UI component.

See Also

getButton(name)

Gets an instance of a custom action button.

Parameters:
name:

myCustomButton.focus();
Angular
app.component.ts
app.component.html
