Custom field in Angular Gantt component

17 May 20259 minutes to read

Generally in Gantt, Custom fields are displayed in the Custom Tab of the Add/Edit dialogs. However, they can be included in the General Tab of Add/Edit Dialog Box using actionBegin and actionComplete events. These events are used to append the custom field to the dialog box. The following code snippets demonstrate the solution.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { GanttModule } from '@syncfusion/ej2-angular-gantt'
import { EditService, SelectionService, ToolbarService } from '@syncfusion/ej2-angular-gantt'
import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';
import { Gantt } from '@syncfusion/ej2-gantt';
import { GanttComponent, ToolbarItem, EditSettingsModel, SelectionSettingsModel } from '@syncfusion/ej2-angular-gantt';
import { CheckBox } from "@syncfusion/ej2-buttons";
import { TextBox, NumericTextBox, MaskedTextBox } from "@syncfusion/ej2-inputs";
import { DatePicker, DateTimePicker } from "@syncfusion/ej2-calendars";
import { DropDownList } from "@syncfusion/ej2-dropdowns";
import { editingData} from './data';

@Component({
imports: [
         GanttModule
    ],
providers: [EditService, SelectionService, ToolbarService],
standalone: true,
    selector: 'app-root',
    template:

})
