DevExtreme jQuery - Customize Appointment Tooltip
When a user clicks an appointment, the Scheduler shows a tooltip that can be customized. For Angular, AngularJS and Knockout apps, DevExtreme provides the dxTemplate markup component. The following code shows how to use dxTemplate to define templates for tooltips.
Angular
HTML
TypeScript
<dx-scheduler
[dataSource]="schedulerData"
appointmentTooltipTemplate="tooltipTemplate"
[currentDate]="currentDate">
<div *dxTemplate="let model of 'tooltipTemplate'">
<i>{{model.appointmentData.text}} ({{model.appointmentData.year}})</i>
<p><img src="{{model.appointmentData.img}}" style="height: 80px"></p>
</div>
</dx-scheduler>
import { DxSchedulerModule } from "devextreme-angular";
// ...
export class AppComponent {
schedulerData = [{
text: "His Girl Friday",
year: 1940,
img: "images/movies/HisGirlFriday.jpg",
startDate: new Date(2016, 4, 24, 9, 10),
endDate: new Date(2016, 4, 24, 11, 20)
},
// ...
];
currentDate = new Date(2016, 4, 24);
}
@NgModule({
imports: [
// ...
DxSchedulerModule
],
// ...
})AngularJS
HTML
JavaScript
<div ng-controller="DemoController">
<div dx-scheduler="{
dataSource: schedulerData,
appointmentTooltipTemplate: 'tooltip',
currentDate: currentDate,
}" dx-item-alias="model">
<div data-options="dxTemplate: { name: 'tooltip' }">
<div style="height: 100px">
<i>{{model.appointmentData.text}} ({{model.appointmentData.year}})</i>
<p><img src="{{model.appointmentData.img}}" style="height: 80px"></p>
</div>
</div>
</div>
</div>angular.module('DemoApp', ['dx'])
.controller('DemoController', function DemoController($scope) {
$scope.schedulerData = [{
text: "His Girl Friday",
year: 1940,
img: "images/movies/HisGirlFriday.jpg",
startDate: new Date(2016, 4, 24, 9, 10),
endDate: new Date(2016, 4, 24, 11, 20)
},
// ...
];
$scope.currentDate = new Date(2016, 4, 24);
});NOTE
The
dx-item-alias directive specifies the variable that is used to access the item object.Knockout
HTML
JavaScript
<div data-bind="dxScheduler: {
dataSource: schedulerData,
appointmentTooltipTemplate: 'tooltip',
currentDate: currentDate
}">
<div style="height: 100px" data-options="dxTemplate: { name: 'tooltip' }">
<i> <span data-bind="text: appointmentData.text"></span>(<span data-bind="text: appointmentData.year"></span>)</i>
<p><img style="height: 80px" data-bind="attr: { src: appointmentData.img }" /></p>
</div>
</div>var viewModel= {
schedulerData: [{
text: "His Girl Friday",
year: 1940,
img: "images/movies/HisGirlFriday.jpg",
startDate: new Date(2016, 4, 24, 9, 10),
endDate: new Date(2016, 4, 24, 11, 20)
},
// ...
],
currentDate: new Date(2016, 4, 24)
};
ko.applyBindings(viewModel);If you use only jQuery, combine HTML markup for tooltips manually with jQuery DOM manipulation methods. To apply this markup, use the appointmentTooltipTemplate callback function as shown in the following code.
JavaScript
var schedulerData = [{
text: "His Girl Friday",
year: 1940,
img: "images/movies/HisGirlFriday.jpg",
startDate: new Date(2016, 4, 24, 9, 10),
endDate: new Date(2016, 4, 24, 11, 20)
},
// ...
];
$(function () {
$("#schedulerContainer").dxScheduler({
dataSource: schedulerData,
currentDate: new Date(2016, 4, 24),
appointmentTooltipTemplate: function (model, index, element) {
element.append("<i>" + model.appointmentData.text + "(" + model.appointmentData.year + ")</i>");
element.append("<p><img style='height: 80px' src='" + model.appointmentData.img + "' /></p>");
}
});
});In addition, you can use a 3rd-party template engine to customize the widget appearance. For more information, see the 3rd-Party Template Engines article.
