Dialog editing in EJ2 TypeScript Grid control

13 Apr 202324 minutes to read

In Dialog edit mode, when you start editing the currently selected row data will be shown on a dialog. You can change the cell values and save edited data to the data source. To enable Dialog edit, set the editSettings.mode as Dialog.

import { Grid, Edit, Toolbar } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';

Grid.Inject(Edit, Toolbar);

let grid: Grid = new Grid({
    dataSource: data,
    toolbar: ['Add', 'Edit', 'Delete'],
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Dialog' },
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100, isPrimaryKey: true },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120, },
        { field: 'Freight', headerText: 'Freight', textAlign: 'Right', editType: 'numericedit', width: 120, format: 'C2' },
        { field: 'ShipCountry', headerText: 'Ship Country', editType: 'dropdownedit', width: 150 }
    ],
    height: 265
});
grid.appendTo('#Grid');

Customize edit dialog

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

In the following example, We have customized the dialog’s height and title of the dialog’s header and also we have changed the button content name in the dialog’s footer.

import { Grid, Edit, Toolbar, DialogEditEventArgs } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
import { Dialog } from '@syncfusion/ej2-popups';

Grid.Inject(Edit, Toolbar);

let grid: Grid = new Grid({
    dataSource: data,
    toolbar: ['Add', 'Edit', 'Delete'],
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Dialog' },
    actionComplete: (args: DialogEditEventArgs) => {
                if ((args.requestType === 'beginEdit' || args.requestType === 'add')) {
                    let dialog: Dialog = args.dialog;
                    // set the height of the dialog
                    dialog.height = 400;
                    // change the header of the dialog
                    dialog.header = args.requestType === 'beginEdit' ? 'Edit Record of ' + args.rowData['CustomerID'] : 'New Customer';
                    // change the footer button name of the dialog
                    dialog.getButtons()[0].content = "Ok";
                    dialog.getButtons()[1].content = "Close";
                }
            },  
    columns: [
                { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right',
                  width: 100, isPrimaryKey: true },
                { field: 'CustomerID', headerText: 'Customer ID', width: 120, },
                { field: 'ShipCountry', headerText: 'Ship Country', width: 150 }],
    height: 265
});
grid.appendTo('#Grid');

The Grid add or edit dialog element has the max-height property, which is calculated based on the available window height. So, in the normal window (1920 x 1080), it is possible to set the dialog’s height up to 658px.

Show or hide columns in dialog editing

The Grid has the option to show hidden columns or hide visible columns while editing in the dialog edit mode by using the actionBegin event of the Grid.

In the actionBegin event, when the requestType is beginEdit or add, the column will be shown or hidden using the column.visible property. When the requestType is save, the properties will be reset to their original state.

In the following example, the CustomerID column is rendered as a hidden column, and the ShipCountry column is rendered as a visible column. In the edit mode, the CustomerID column will be changed to a visible state and the ShipCountry column will be changed to a hidden state.

import { Grid, Edit, Toolbar, DialogEditEventArgs } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';

Grid.Inject(Edit, Toolbar);

let grid: Grid = new Grid({
    dataSource: data,
    toolbar: ['Add', 'Edit', 'Delete'],
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Dialog' },
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100, isPrimaryKey: true },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120, visible: false },
        { field: 'Freight', headerText: 'Freight', textAlign: 'Right', editType: 'numericedit', width: 120, format: 'C2' },
        { field: 'ShipCountry', headerText: 'Ship Country', width: 150 }
    ],
    height: 265,
    actionBegin: function(args: DialogEditEventArgs) {
        if ((args.requestType === 'beginEdit' || args.requestType === 'add')) {
            for (var i = 0; i < this.columns.length; i++) {
                if (this.columns[i].field == "CustomerID") {
                    this.columns[i].visible = true;
                }
                else if (this.columns[i].field == "ShipCountry") {
                    this.columns[i].visible = false;
                }
            }
        }
        if (args.requestType === 'save') {
            for (var i = 0; i < this.columns.length; i++) {
                if (this.columns[i].field == "CustomerID") {
                    this.columns[i].visible = false;
                }
                else if (this.columns[i].field == "ShipCountry") {
                    this.columns[i].visible = true;
                }
            }
        }
    }
});
grid.appendTo('#Grid');

Use wizard like dialog editing

Wizard helps you to create intuitive step-by-step forms to fill. You can achieve the wizard-like editing by using the dialog template feature. It supports your own editing template by defining the editSettings.mode as Dialog and editSetting.template as SCRIPT element ID or HTML string which holds the template.

The following example demonstrates the wizard-like editing in the grid with obtrusive validation.

import { Grid, Edit, Toolbar, DialogEditEventArgs } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
import { DropDownList } from '@syncfusion/ej2-dropdowns';
import { DataUtil } from '@syncfusion/ej2-data';
import { CheckBox } from '@syncfusion/ej2-buttons';

Grid.Inject(Edit, Toolbar);

let countryData: {}[] = DataUtil.distinct(data, 'ShipCountry', true);

let grid: Grid = new Grid({
    dataSource: data,
    toolbar: ['Add', 'Edit', 'Delete'],
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Dialog', template: '#dialogtemplate' },
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100, isPrimaryKey: true, validationRules: { required: true }},
        { field: 'CustomerID', headerText: 'Customer ID', width: 120, validationRules: { required: true }},
        { field: 'ShipCountry', headerText: 'Ship Country', width: 150 }
    ],
    height: 265,
    actionComplete: (args: DialogEditEventArgs) => {
        if ((args.requestType === 'beginEdit' || args.requestType === 'add')) {
            new DropDownList({value: args.rowData.ShipCountry, popupHeight: '300px', floatLabelType: 'Always',
                dataSource: countryData, fields: {text: 'ShipCountry', value: 'ShipCountry'}, placeholder: 'Ship Country'}, args.form.elements.namedItem('ShipCountry') as HTMLInputElement);
            new CheckBox({ label: 'Verified', checked: args.rowData.Verified }, args.form.elements.namedItem('Verified'));
            // Set initail Focus
            if (args.requestType === 'beginEdit') {
                (args.form.elements.namedItem('CustomerID')as HTMLInputElement).focus();
            }
            initializeWizard();
        }
    }
});
grid.appendTo('#Grid');

function initializeWizard() {
    let currentTab = 0;

    document.getElementById('nextBtn').onclick = function () {
        if (validate()) {
            if (this.innerHTML !== 'SUBMIT'){
                currentTab++;
                nextpre(currentTab);
            } else {
                grid.endEdit();
            }
        }
    }
    function validate(tab) {
        let valid: boolean = true;
            [].slice.call(document.getElementById('tab' + currentTab).querySelectorAll('[name]')).forEach(element => {
            element.form.ej2_instances[0].validate(element.name);
            if (element.getAttribute('aria-invalid') === 'true'){
                valid = false;
            }
        });
        if (!valid) {
        return false;
        }
        return true;
    }
    document.getElementById('prevBtn').onclick = function () {
        if (validate()) {
            currentTab--;
            nextpre(currentTab);
        }
    }
}


function nextpre(current) {
    let tabs: HTMLElement[] = [].slice.call(document.getElementsByClassName('tab'))
    tabs.forEach(element => element.style.display = 'none');
    tabs[current].style.display = '';
    if(current) {
        document.getElementById('prevBtn').style.display = '';
        document.getElementById('nextBtn').innerHTML = 'SUBMIT';
    } else {
        document.getElementById('prevBtn').style.display = 'none';
        document.getElementById('nextBtn').innerHTML = 'NEXT';
    }
}

In dialog edit mode, a dialog will show up when editing the currently selected row or adding a new row. By default, you can save or cancel the edited changes by clicking the Save or Cancel button in the dialog’s footer. Along with these buttons, it is possible to add a custom button in the footer section using the actionComplete event of the Grid.

In the following sample, using the dialog argument of the actionComplete event, the action for the custom button can be customized.

import { Grid, Edit, Toolbar, DialogEditEventArgs } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';

Grid.Inject(Edit, Toolbar);

let grid: Grid = new Grid({
    dataSource: data,
    toolbar: ['Add', 'Edit', 'Delete'],
    editSettings: {
        allowEditing: true,
        allowAdding: true,
        allowDeleting: true,
        mode: 'Dialog',
    },
    actionComplete: actionComplete,
    columns: [{
        field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100, isPrimaryKey: true },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'Freight', headerText: 'Freight', textAlign: 'Right', editType: 'numericedit', width: 120, format: 'C2' },
       { field: 'ShipCountry', headerText: 'Ship Country', editType: 'dropdownedit', width: 150 },
    ]
});
grid.appendTo('#Grid');

function actionComplete(args) {
    if (args.requestType === 'beginEdit' || args.requestType === 'add') {
        let newFooterButton = {
            buttonModel: { content: 'custom' },
            click: onCustomButtonClick
        };
        args.dialog.buttons.push(newFooterButton);
        args.dialog.refresh();
    }
}

function onCustomButtonClick() {
    alert('Add/Edit dialog custom footer button clicked');
}
