This section describes members used to manipulate the UI component.

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.

Gets the UI component's height in pixels.

The UI component's height in pixels.

Collapses a group with a specific index.

A Promise that is resolved if the group is collapsed and rejected otherwise. It is a native Promise or a jQuery.Promise when you use jQuery.

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

The component's default device properties.

Object structure:

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.

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 List UI component in an application executed on the desktop.

DevExpress.ui.dxList.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the List properties
    }
});

import List, { Properties } from "devextreme/ui/list";
// ...
export class AppComponent {
    constructor () {
        List.defaultOptions<Properties>({
            device: { deviceType: "desktop" },
            options: {
                // Here go the List properties
            }
        });
    }
}

<template>
    <div>
        <DxList id="list1" />
        <DxList id="list2" />
    </div>
</template>
<script>
import DxList from "devextreme-vue/list";
import List from "devextreme/ui/list";

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

export default {
    components: {
        DxList
    }
}
</script>

import dxList from "devextreme/ui/list";
import List from "devextreme-react/list";

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

export default function App() {
    return (
        <div>
            <List id="list1" />
            <List id="list2" />
        </div>
    )
}

You can also set rules for multiple device types:

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

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

import List, { Properties } from "devextreme/ui/list";
// ...
export class AppComponent {
    constructor () {
        const devicesConfig = [
            { deviceType: 'desktop' },
            { deviceType: 'tablet' },
            { deviceType: 'phone' },
        ];

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

<template>
    <div>
        <DxList />
    </div>
</template>
<script>
import DxList from "devextreme-vue/list";
import List from "devextreme/ui/list";

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

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

export default {
    components: {
        DxList
    }
}
</script>

import dxList from "devextreme/ui/list";
import List from "devextreme-react/list";

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

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

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

Removes an item found using its DOM node.

Removes an item with a specific index.

The item's index. If the items are grouped, the index represents an object defining the group and item indexes: { group: 0, item: 0 }.

Disposes of all the resources allocated to the List instance.

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

$("#myList").dxList("dispose");
$("#myList").remove();

Use conditional rendering instead of this method:

<dx-list ...
    *ngIf="condition">
</dx-list>

Use conditional rendering instead of this method:

<template>
    <DxList ...
        v-if="condition">
    </DxList>
</template>

<script>
import DxList from 'devextreme-vue/list';

export default {
    components: {
        DxList
    }
}
</script>

Use conditional rendering instead of this method:

import React from 'react';

import List from 'devextreme-react/list';

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

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

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

Gets the root UI component element.

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.

Expands a group with a specific index.

Sets focus on the UI component.

Gets the instance of a UI component found using its DOM node.

The UI component's container.

The UI component's instance.

getInstance is a static method that the UI component class supports. The following code demonstrates how to get the List instance found in an element with the myList ID:

// Modular approach
import List from "devextreme/ui/list";
...
let element = document.getElementById("myList");
let instance = List.getInstance(element) as List;

// Non-modular approach
let element = document.getElementById("myList");
let instance = DevExpress.ui.dxList.getInstance(element);

• "backspace"
• "tab"
• "enter"
• "escape"
• "pageUp"
• "pageDown"
• "end"
• "home"
• "leftArrow"
• "upArrow"
• "rightArrow"
• "downArrow"

Reorders items found using their DOM nodes.

The DOM node of the item to be reordered.

The DOM node of the item after which the reordered item should be placed.

Reorders items with specific indexes.

The index of the item to be reordered.

The index of the item after which the reordered item should be placed.

If the UI component displays a grouped list, the item index should be specified like the following:

Where the group property specifies the group index, and the index property specifies the index of the required item within the group.

This code will move the 4th item of the 1st group to the 3rd position in the 3rd group:

$("#myList").dxList("instance").reorderItem({
    group: 1,
    index: 4
},
{
    group: 3,
    index: 2
});

This method reorders items in the

array, but it does not affect the
