Angular Gallery - Customize Item Appearance

Gallery items are not sctrictly images. They can contain text or other elements of your choice. For a minor customization of Gallery items, you can define specific fields in item data objects. For example, the following code generates two items: one is disabled and the other has a specified alt attribute.

jQuery
JavaScript
$(function () {
    $("#galleryContainer").dxGallery({
        dataSource: [{
            imageSrc: "https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person1.png",
            disabled: true
        }, {
            imageSrc: "https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person2.png",
            imageAlt: "Peter"
        }],
        height: 300
    });
});
Angular
HTML
TypeScript
<dx-gallery
    [dataSource]="galleryDataSource"
    [height]="300">
</dx-gallery>
import { DxGalleryModule } from "devextreme-angular";
// ...
export class AppComponent {
    galleryDataSource = [{
        imageSrc: "https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person1.png",
        disabled: true
    }, {
        imageSrc: "https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person2.png",
        imageAlt: "Peter"
    }];
}
@NgModule({
    imports: [
        // ...
        DxGalleryModule
    ],
    // ...
})
Vue
<template>
    <DxGallery
        :data-source="dataSource"
        :height="300"
    />
</template>

<script>
import 'devextreme/dist/css/dx.light.css';

import { DxGallery } from 'devextreme-vue/gallery';

export default {
    components: {
        DxGallery
    },
    data() {
        return {
            dataSource: [{
                imageSrc: 'https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person1.png',
                disabled: true
            }, {
                imageSrc: 'https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person2.png',
                imageAlt: 'Peter'
            }]
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import { Gallery } from 'devextreme-react/gallery';

const dataSource = [{
    imageSrc: 'https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person1.png',
    disabled: true
}, {
    imageSrc: 'https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person2.png',
    imageAlt: 'Peter'
}];

class App extends React.Component {
    render() {
        return (
            <Gallery
                dataSource={dataSource}
                height={300}
            />
        );
    }
}

export default App;

If you need a more flexible solution, define an itemTemplate.

jQuery
JavaScript
$(function () {
    $("#galleryContainer").dxGallery({
        dataSource: galleryData,
        height: 300,
        itemTemplate: function(e){
            e.itemElement.empty();
            e.itemElement.append("<p><b>Name</b>: " + e.itemData.name + "</p>");
            e.itemElement.append("<img src=\"" + e.itemData.path + "\" alt=\"" + e.itemData.name + "\"/>");
        }
    });
});
Angular
HTML

<dx-gallery
    [dataSource]="galleryDataSource"
    [height]="300"
    itemTemplate="item">
    <div *dxTemplate="let data of 'item'">
        <p><b>Name</b>: <span>{{data.name}}</span></p>
        <img src="{{data.path}}" alt="{{data.name}}" />
    </div>
</dx-gallery>
import { DxGalleryModule } from "devextreme-angular";

export class AppComponent {
    galleryDataSource = [

    ];

    // ...
})

        <template #item="{ data }">
            <div>

jQuery

You can also customize an individual Gallery item. For this purpose, declare a template for this item as a script and pass its id to the template field of the item's data object.

HTML
JavaScript
<script id="individualTemplate" type="text/html">
    <!-- ... -->
</script>
const galleryData = [{
    imageSrc: "https://js.devexpress.com/Content/images/doc/24_2/PhoneJS/person1.png",
    imageAlt: "Maria",
    template: $("#individualTemplate"),
},
    // ...
];
