Editor window and quick popups

11 Jul 202424 minutes to read

Scheduler makes use of popups and dialog to display the required notifications, as well as includes an editor window with event fields for making the appointment creation and editing process easier. You can also easily customize the editor window and the fields present in it, and can also apply validations on those fields.

Event editor

The editor window usually opens on the Scheduler, when a cell or event is double clicked. When a cell is double clicked, the detailed editor window opens in “Add new” mode, whereas when an event is double clicked, the same is opened in an “Edit” mode.

In mobile devices, you can open the detailed editor window in edit mode by clicking the edit icon on the popup, that opens on single tapping an event. You can also open it in add mode by single tapping a cell, which will display a + indication, clicking on it again will open the editor window.

NOTE

You can also prevent the editor window from opening, by rendering Scheduler in a readonly mode or by doing code customization within the popupOpen event.

You can change the header title and the text of buttons displayed at the footer of the editor window by changing the appropriate localized word collection used in the Scheduler.

Field validation

It is possible to validate the required fields of the editor window from client-side before submitting it, by adding appropriate validation rules to each field. The appointment fields have been extended to accept both string and object type values. To perform validations, it is necessary to specify object values for the event fields.

@using Syncfusion.EJ2.Schedule

@{
    var validationRules = new Dictionary<string, object>() { { "required", true } };
    var locationValidationRules = new Dictionary<string, object>() { { "required", true }, { "regex", new string[] { "^[a-zA-Z0-9- ]*$", "Special character(s) not allowed in this field" } } };
    var descriptionValidationRules = new Dictionary<string, object>() { { "required", true }, { "minLength", 5 }, { "maxLength", 500 } };
}

Applicable validation rules can be referred from form validation documentation.

Add additional fields to the default editor

The additional fields can be added to the default event editor by making use of the popupOpen event which gets triggered before the event editor opens on the Scheduler. The popupOpen is a client-side event that triggers before any of the generic popups opens on the Scheduler. The additional field (any of the form elements) should be added with a common class name e-field, so as to handle and process those additional data along with the default event object. In the following example, an additional field Event Type has been added to the default event editor and its value is processed accordingly.

@using Syncfusion.EJ2.Schedule

Customizing the default time duration in editor window

In default event editor window, start and end time duration are processed based on the interval value set within the timeScale property. By default, interval value is set to 30, and therefore the start/end time duration within the event editor will be in a 30 minutes time difference. You can change this duration value by changing the duration option within the popupOpen event as shown in the following code example.

@using Syncfusion.EJ2.Schedule

<ejs-schedule id="schedule" height="550" selectedDate="new DateTime(2023, 2, 15)" views="@ViewBag.view" popupOpen="onPopupOpen">

How to prevent the display of editor and quick popups

It is possible to prevent the display of editor and quick popup windows by passing the value true to cancel option within the popupOpen event.

@using Syncfusion.EJ2.Schedule

<ejs-schedule id="schedule" height="550" selectedDate="new DateTime(2018, 2, 15)" views="@ViewBag.view" popupOpen="onPopupOpen">
    <e-schedule-eventsettings dataSource="@ViewBag.datasource"></e-schedule-eventsettings>

        new ScheduleView { Option = Syncfusion.EJ2.Schedule.View.Week },
        new ScheduleView { Option = Syncfusion.EJ2.Schedule.View.WorkWeek }
    };
    ViewBag.view = viewOption;
    return View();
}

public List<AppointmentData> GetScheduleData()
{
    List<AppointmentData> appData = new List<AppointmentData>();
    appData.Add(new AppointmentData
    {
        Id = 1,
        Subject = "Meeting",
        StartTime = new DateTime(2018, 2, 15, 10, 0, 0),
        EndTime = new DateTime(2018, 2, 15, 12, 30, 0),
        IsAllDay = false,
    });
    return appData;

    public string Subject { get; set; }
    public DateTime StartTime { get; set; }
    public DateTime EndTime { get; set; }
    public bool IsAllDay { get; set; }
}

In case, if you need to prevent only specific popups on Scheduler, then you can check the condition based on the popup type. The types of the popup that can be checked within the popupOpen event are as follows.

Type Description
Editor For Detailed editor window.
QuickInfo For Quick popup which opens on cell click.
EditEventInfo For Quick popup which opens on event click.
ViewEventInfo For Quick popup which opens on responsive mode.
EditorContainer For more event indicator popup.

Quick popups

The quick info popups are the ones that gets opened, when a cell or appointment is single clicked on the desktop mode. On single clicking a cell, you can simply provide a subject and save it. Also, while single clicking on an event, a popup will be displayed where you can get the overview of the event information. You can also edit or delete those events through the options available in it.

By default, these popups are displayed over cells and appointments of Scheduler and to disable this action, set false to showQuickInfo property.

Customizing event editor using template

The event editor window can be customized by making use of the editorTemplate option. Here, the custom window design is built with the required fields using the script template and its type should be of text/x-template.

Each field defined within template should contain the e-field class, so as to allow the processing of those field values internally. The ID of this customized script template section is assigned to the editorTemplate option, so that these customized fields will be replaced onto the default editor window.

Note: e-field class only applicable for DropDownList, DateTimePicker, MultiSelect, DatePicker, CheckBox and TextBox components. Since we have processed the field values internally for the above mentioned components.

As we are using our Syncfusion sub-components within our editor using template in the following example, the custom defined form elements needs to be configured as required Syncfusion components such as DropDownList and DateTimePicker within the popupOpen event. This particular step can be skipped, if the user needs to simply use the usual form elements.

Display Customizing Event Editor Using Template in ASP.NET Core Scheduler

The editor window’s header and footer can be enhanced with custom designs using the editorHeaderTemplate and editorFooterTemplate options. To achieve this, create a script template that includes the necessary fields. Ensure that the template type is set to text/x-template.

In this demo, we tailor the editor’s header according to the appointment’s subject field using the editorHeaderTemplate. Furthermore, we make use of the editorFooterTemplate to handle the functionality of validating specific fields before proceeding with the save action or canceling it if validation requirements are not
met.

How to save the customized event editor using template

The e-field class is not added to each field defined within the template, so you should allow to set those field values externally by using the popupClose event.

NOTE

You can allow to retrieve the data only on the save and delete option. Data cannot be retrieved on the close and cancel options in the editor window.

The following code example shows how to save the customized event editor using a template by the popupClose event.

In case, if you need to prevent only specific popups on Scheduler, then you can check the condition based on the popup type. The types of the popup that can be checked within the popupClose event are as follows.

Type Description
Editor For Detailed editor window.
QuickInfo For Quick popup which opens on cell click.
EditEventInfo For Quick popup which opens on event click.
ViewEventInfo For Quick popup which opens on responsive mode.
EventContainer For more event indicator popup.
RecurrenceAlert For edit recurrence event alert popup.
DeleteAlert For delete confirmation popup.
ValidationAlert For validation alert popup.
RecurrenceValidationAlert For recurrence validation alert popup.

More events indicator and popup

When the number of appointments count that lies on a particular time range * default appointment height exceeds the default height of a cell in month view and all other timeline views, a + more text indicator will be displayed at the bottom of those cells. This indicator denotes that the cell contains few more appointments in it and clicking on that will display a popup displaying all the appointments present on that day.

NOTE

To disable this option of showing popup with all hidden appointments, while clicking on the text indicator, you can do code customization within the popupOpen event.

The same indicator is displayed on all-day row in calendar views such as day, week and work week views alone, when the number of appointment count present in a cell exceeds three. Clicking on the text indicator here will not open a popup, but will allow the expand/collapse option for viewing the remaining appointments present in the all-day row.

The following code example shows how to disable the display of such popups while clicking on the more text indicator.
