DevExtreme Angular - Customize Resource Headers

For AngularJS and Knockout apps, DevExtreme provides a markup component called dxTemplate. The following code shows how you can use dxTemplate to define custom templates for resource headers.

Angular

TypeScript
<dx-scheduler 
    [dataSource]="schedulerData"
    [currentDate]="currentDate"
    [groups]="['roomId']"
    resourceCellTemplate="headerTemplate">
    <dxi-resource
        fieldExpr="roomId"
        [dataSource]="rooms" >
    </dxi-resource>
    <div *dxTemplate="let appointment of 'headerTemplate'">
        <i style="color: blue">{{appointment.text}}</i>
    </div>
</dx-scheduler>
import { DxSchedulerModule } from 'devextreme-angular';
// ...
export class AppComponent {
    schedulerData = [{ 
        text: "Meeting",
        startDate: new Date(2016, 4, 24, 9, 10),
        endDate: new Date(2016, 4, 24, 11, 20),
        roomId: 1
    }, 
    // ...
    ];
    rooms = [
        { id: 1, text: 'Room101', color: 'green' },
        { id: 2, text: 'Room102', color: 'red' },
        // ...
    ];
    currentDate = new Date(2016, 4, 24);
}
@NgModule({
    imports: [
        // ...
        DxSchedulerModule
    ],
    // ...
})

<div ng-controller="DemoController">
    <div dx-scheduler="{
        dataSource: schedulerData,
        currentDate: currentDate,
        resources: [ roomResource ],
        groups: [ 'roomId' ],
        resourceCellTemplate: 'header'
    }" dx-item-alias="item">
        <div data-options="dxTemplate: { name: 'header' }">
            <i style="color: blue">{{item.text}}</i>
        </div>
    </div>
</div>
angular.module('DemoApp', ['dx'])
    .controller('DemoController', function DemoController($scope) {
        $scope.schedulerData = [{
            text: "Meeting",
            startDate: new Date(2016, 4, 24, 9, 10),
            endDate: new Date(2016, 4, 24, 11, 20),
            roomId: 1
        }, 
        // ...
        ];
        $scope.roomResource = { 
            fieldExpr: 'roomId', 
            dataSource: [
                { id: 1, text: 'Room101', color: 'green' },
                { id: 2, text: 'Room102', color: 'red' },
                // ...
            ] 
        };
        $scope.currentDate = new Date(2016, 4, 24); 
    });
NOTE
The dx-item-alias directive specifies the variable that is used to access the item object.

<div data-bind="dxScheduler: {

    roomResource: { 
        fieldExpr: 'roomId', 
        dataSource: [
            { id: 1, text: 'Room101', color: 'green' },
            { id: 2, text: 'Room102', color: 'red' },
            // ...

    },
    currentDate: new Date(2016, 4, 24)
};

ko.applyBindings(viewModel);

If you use jQuery alone, combine the HTML markup for resource headers manually with jQuery DOM manipulation methods. To apply this markup, use the resourceCellTemplate callback function as shown in the following code.

JavaScript
var schedulerData = [{
    text: "Meeting",
    startDate: new Date(2016, 4, 24, 9, 10),
    endDate: new Date(2016, 4, 24, 11, 20),
    roomId: 1
}, 
// ...
];
var roomResource = { 
    fieldExpr: 'roomId', 
    dataSource: [
        { id: 1, text: 'Room101', color: 'green' },
        { id: 2, text: 'Room102', color: 'red' },
        // ...
    ] 
};

$(function () {
    $("#schedulerContainer").dxScheduler({
        dataSource: schedulerData,
        currentDate: new Date(2016, 4, 24),
        resources: [ roomResource ],
        groups: [ 'roomId' ],
        resourceCellTemplate: function (data, index, element) {
            element.append("<i style='color: blue'>" + data.text + "</i>");
        }
    });
});

In addition, you can use a 3rd-party template engine to customize widget appearance. For more information, see the 3rd-Party Template Engines article.
