Cell customization in Angular Schedule component

11 Jul 202424 minutes to read

The cells of the Scheduler can be easily customized either using the cell template or RenderCell event.

Setting cell dimensions in all views

The height and width of the Scheduler cells can be customized either to increase or reduce its size through the cssClass property, which overrides the default CSS applied on cells.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'



import { Component, ViewChild, ViewEncapsulation } from '@angular/core';
import { ScheduleComponent, EventSettingsModel, ActionEventArgs, DayService, WeekService, WorkWeekService, MonthService, AgendaService,
    MonthAgendaService } from '@syncfusion/ej2-angular-schedule';
import { scheduleData } from './datasource';

@Component({
imports: [
        
        ScheduleModule,
        ButtonModule
    ],
standalone: true,
  selector: 'app-root',
  providers: [DayService, WeekService, WorkWeekService, MonthService, AgendaService,
    MonthAgendaService],
  // specifies the template string for the Schedule component
  template: `<ejs-schedule #scheduleObj width='100%' height='550px' cssClass='schedule-cell-dimension' [selectedDate]="selectedDate" [eventSettings]="eventSettings"> </ejs-schedule>`,
  styles: [`
  .schedule-cell-dimension.e-schedule .e-vertical-view .e-date-header-wrap table col,

`],
encapsulation: ViewEncapsulation.None
})
export class AppComponent {
    @ViewChild('scheduleObj', { static: true })
    public scheduleObj?: ScheduleComponent;
    public selectedDate: Date = new Date(2018, 1, 15);
    public eventSettings: EventSettingsModel = { dataSource: scheduleData };

Check for cell availability

You can check whether the given time range slots are available for event creation or already occupied by other events using the isSlotAvailable method. In the following code example, if a specific time slot already contains an appointment, then no more appointments can be added to that cell.

Note: The isSlotAvailable is centered around verifying appointments within the present view’s date range. Yet, it does not encompass an evaluation of availability for recurrence occurrences that fall beyond this particular date range.

Customizing cells in all the views

It is possible to customize the appearance of the cells using both template options and renderCell event on all the views.

Using template

The cellTemplate option accepts the template string and is used to customize the cell background with specific images or appropriate text on the given date values.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'



import { Component, ViewEncapsulation } from '@angular/core';
import { View, DayService, WeekService, TimelineViewsService, MonthService, WorkWeekService, AgendaService, MonthAgendaService  } from '@syncfusion/ej2-angular-schedule';

@Component({
imports: [
        
        ScheduleModule,
        ButtonModule
    ],
standalone: true,
  selector: 'app-root',
  providers: [DayService, WeekService, TimelineViewsService, MonthService, WorkWeekService, AgendaService,
    MonthAgendaService ],
  // specifies the template string for the Schedule component
   template: `<ejs-schedule width='100%' height='550px' [selectedDate]="selectedDate" [(currentView)]="currentView" cssClass="schedule-cell-template">
    <ng-template #cellTemplate let-data>
      <div class="templatewrap" *ngIf="data.type == 'workCells'" [innerHTML]="getWorkCellText(data.date)"></div>
      <div class="templatewrap" *ngIf="data.type == 'monthCells'" [innerHTML]="getMonthCellText(data.date)"></div>
    </ng-template>
  </ejs-schedule>`,
  styles: [`
  .schedule-cell-template.e-schedule .e-month-view .e-work-cells {
    position: relative;
  }
  .templatewrap {
  text-align: center;
  /* In MONTH view the cell template is a SIBLING of event templates. So which is necessary to set the parent position relative and the child position absolute with 100% width */
  position: absolute;
  width: 100%;
}

.templatewrap img {
  width: 20px;
  height: 20px;
}
`],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
    public selectedDate: Date = new Date(2017, 11, 16);
    public currentView: View = 'Week';
    getMonthCellText(date: Date): string {
      if (date.getMonth() === 10 && date.getDate() === 23) {
        return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/birthday.svg" />';
      } else if (date.getMonth() === 11 && date.getDate() === 9) {
          return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/get-together.svg" />';
      } else if (date.getMonth() === 11 && date.getDate() === 13) {
          return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/birthday.svg" />';
      } else if (date.getMonth() === 11 && date.getDate() === 22) {
          return '<img src= "https://ej2.syncfusion.com/demos/src/schedule/images/thanksgiving-day.svg" />';
      } else if (date.getMonth() === 11 && date.getDate() === 24) {

      }
      return '';
    }
    getWorkCellText(date: Date): string {
        let weekEnds: number[] = [0, 6];
        if (weekEnds.indexOf(date.getDay()) >= 0) {
            return "<img src='https://ej2.syncfusion.com/demos/src/schedule/images/newyear.svg' />";
        }
        return '';
    }
 }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Using renderCell event

An alternative to cellTemplate is the renderCell event, which can also be used to customize the cells with appropriate images or formatted text values.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { DayService, WeekService, WorkWeekService, MonthService, AgendaService, MonthAgendaService} from '@syncfusion/ej2-angular-schedule'



import { Component, ViewEncapsulation } from '@angular/core';
import { EventSettingsModel, RenderCellEventArgs } from '@syncfusion/ej2-angular-schedule';
import { scheduleData } from './datasource';
import { createElement } from '@syncfusion/ej2-base';

@Component({
imports: [
        
        ScheduleModule,
        ButtonModule
    ],

providers: [DayService, 
                WeekService, 
                WorkWeekService, 
                MonthService,
                AgendaService,
                MonthAgendaService],
standalone: true,
  selector: 'app-root',
  // specifies the template string for the Schedule component
  template: `<ejs-schedule width='100%' height='550px' currentView='Month' [selectedDate]="selectedDate" [eventSettings]="eventSettings" (renderCell)="onRenderCell($event)">
  <e-views> <e-view option="Day"></e-view> <e-view option="Week"></e-view> <e-view option="Month"></e-view> </e-views> </ejs-schedule>`,
  styleUrls: ['./index.css'],
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  public selectedDate: Date = new Date(2018, 1, 14);
  public eventSettings: EventSettingsModel = { dataSource: scheduleData };
  onRenderCell(args: RenderCellEventArgs): void {
    if (args.elementType == 'workCells' || args.elementType == 'monthCells') {
      let weekEnds: number[] = [0, 6];
      if (args.date && weekEnds.indexOf((args.date).getDay()) >= 0) {
        let ele: HTMLElement = createElement('div', {
          innerHTML: "<img src='https://ej2.syncfusion.com/demos/src/schedule/images/newyear.svg' />",
          className: 'templatewrap'
        });
        (args.element).appendChild(ele);
      }
    }
  }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

You can customize cells such as work cells, month cells, all-day cells, header cells, resource header cells using renderCell event by checking the elementType option within the event. You can check elementType with any of the following.

Element type	Description
dateHeader	triggers on header cell rendering.
monthDay	triggers on header cell in month view rendering.
resourceHeader	triggers on resource header cell rendering.
alldayCells	triggers on all day cell rendering.
emptyCells	triggers on empty cell rendering on header bar.
resourceGroupCells	triggers on rendering of work cells for parent resource.
workCells	triggers on work cell rendering.
monthCells	triggers on month cell rendering.
majorSlot	triggers on major time slot cell rendering.
minorSlot	triggers on minor time slot cell rendering.
weekNumberCell	triggers on cell displaying week number.

Customizing cell header in month view

The month header of each date cell in the month view can be customized using the cellHeaderTemplate option which accepts the string or HTMLElement. The corresponding date can be accessed with the template.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'

                AgendaService,
                MonthAgendaService],
standalone: true,
  selector: 'app-root',

  };
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Customizing the minimum and maximum date values

Providing the minDate and maxDate property with some date values, allows the Scheduler to set the minimum and maximum date range. The Scheduler date that lies beyond this minimum and maximum date range will be in a disabled state so that the date navigation will be blocked beyond the specified date range.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ScheduleModule } from '@syncfusion/ej2-angular-schedule'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { DayService, WeekService, WorkWeekService, MonthService, AgendaService, MonthAgendaService} from '@syncfusion/ej2-angular-schedule'



import { Component } from '@angular/core';
import { View, EventSettingsModel } from '@syncfusion/ej2-angular-schedule';
import { scheduleData } from './datasource';

@Component({
imports: [
        
        ScheduleModule,
        ButtonModule
    ],

providers: [DayService, 
                WeekService, 
                WorkWeekService, 
                MonthService,
                AgendaService,
                MonthAgendaService],
standalone: true,
  selector: 'app-root',
  template: `<ejs-schedule width='100%' height='550px' [selectedDate]='selectedDate' [minDate]='minDate' [maxDate]='maxDate' [currentView]='currentView' [eventSettings]='eventSettings'></ejs-schedule>`
})
export class AppComponent {
  public selectedDate: Date = new Date(2018, 1, 17);
  public minDate: Date = new Date(2017, 4, 17);
  public maxDate: Date = new Date(2018, 8, 17);
  public eventSettings: EventSettingsModel = { dataSource: scheduleData };
  public currentView: View = 'Month';
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

By default, the minDate property value is set to new Date(1900, 0, 1) and maxDate property value is set to new Date(2099, 11, 31). The user can also set the customized minDate and maxDate property values.

Customizing the weekend cells background color

You can customize the background color of weekend cells by utilizing the renderCell event and checking the elementType option within the event.

public onRenderCell(args: RenderCellEventArgs): void {
    if (args.elementType == "workCells") {
      if (args.date) {
        if (args.date.getDay() === 6) {
          (args.element as any).style.background = '#ffdea2';
        }
        if (args.date.getDay() === 0) {
          (args.element as any).style.background = '#ffdea2';
        }
      }
    }
}

And, the background color for weekend cells in the Month view through the cssClass property, which overrides the default CSS applied on cells.

.schedule-cell-customization.e-schedule .e-month-view .e-work-cells:not(.e-work-days) {
    background-color: #f08080;
}

app.component.ts

import { NgModule } from '@angular/core'

import { Component, ViewEncapsulation } from '@angular/core';
import {
  EventSettingsModel, View, RenderCellEventArgs, DayService, WeekService, WorkWeekService,
  MonthService, AgendaService, ResizeService, DragAndDropService, ScheduleModule
} from '@syncfusion/ej2-angular-schedule';
import { defaultData } from './datasource';

@Component({
imports: [

How to disable multiple cell and row selection in Schedule

By default, the allowMultiCellSelection and allowMultiCellSelection properties of the Schedule are set to true. So, the Schedule allows user to select multiple cells and rows. If the user want to disable this multiple cell and row selection. The user can disable this feature by setting up false to these properties.
