21 Sep 20225 minutes to read

You can customize the appearance of the edit dialog in the actionComplete event based on requestType as beginEdit or add.

In the below example, we have changed the dialog’s header text for editing and adding records.

import { Component, OnInit, ViewChild } from '@angular/core';
import { projectData } from './datasource';
import { TreeGridComponent, EditSettingsModel, ToolbarItems , EditService, ToolbarService  } from '@syncfusion/ej2-angular-treegrid';
import { DialogEditEventArgs } from '@syncfusion/ej2-angular-grids';
import { Dialog } from '@syncfusion/ej2-popups';

@Component({
    selector: 'app-container',
    providers: [EditService, ToolbarService],
    template: `<ejs-treegrid #treegrid [dataSource]='data' idMapping='TaskID' parentIdMapping='parentID' [treeColumnIndex]='1' [height]='265' [editSettings]='editSettings' [toolbar]='toolbar' (actionComplete)="actionComplete($event)" >
        <e-columns>
            <e-column field='TaskID' headerText='Task ID' isPrimaryKey='true'  width='70' textAlign='Right'></e-column>
            <e-column field='TaskName' headerText='Task Name' width='100' ></e-column>
            <e-column field='StartDate' headerText='Start Date' textAlign='Right' [format]='formatOptions' editType='datepickeredit' [edit]='editOptions' width='90'></e-column>
            <e-column field='EndDate' headerText='End Date' width='90' [format]='formatOptions' editType='datepickeredit' [edit]='editOptions' textAlign='Right'></e-column>
            <e-column field='Duration' headerText='Duration' width='90' textAlign='Right'></e-column>
            <e-column field='Priority' headerText='Priority' width='90'></e-column>
        </e-columns>
    </ejs-treegrid>`,
})
export class AppComponent implements OnInit {

    public data: Object[] = [];
    public editSettings: EditSettingsModel;
    public toolbar: ToolbarItems[];
    public editOptions: Object;
    public formatOptions: Object;

    ngOnInit(): void {
        this.data = projectData;
        this.editOptions = { params: { format: 'y/M/d' } };
        this.formatOptions = { format: 'y/M/d', type: 'date' };
        this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Dialog' };
        this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel'];
    }
    actionComplete(args: DialogEditEventArgs) {
        if ((args.requestType === 'beginEdit' || args.requestType === 'add')) {
            const dialog = args.dialog as Dialog;
            const TaskName = 'TaskName';
            dialog.height = 400;
            // change the header of the dialog
            dialog.header = args.requestType === 'beginEdit' ? 'Record of ' + args.rowData[TaskName] : 'New Customer';
        }
    }
