Enable editing in single click in Angular Grid component

Normal Editing

You can make a row editable on a single click with Normal mode of editing in Grid, by using the startEdit and endEdit methods.

Bind the mouseup event for Grid and in the event handler call the startEdit and endEdit, based on the clicked target element.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { EditSettingsModel, ToolbarItems, GridComponent } from '@syncfusion/ej2-angular-grids';
import { MouseEventArgs } from '@syncfusion/ej2-base';
import { data } from './datasource';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid [dataSource]='data' [editSettings]='editSettings' [toolbar]='toolbar' allowPaging='true' (load)='load($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=100 isPrimaryKey='true'></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' width=120></e-column>
                    <e-column field='Freight' headerText='Freight' textAlign= 'Right' width=120 format= 'C2'></e-column>
                    <e-column field='ShipCountry' headerText='Ship Country' width=150></e-column>
                </e-columns>
                </ejs-grid>`
})

export class AppComponent implements OnInit {

    public data: object[];
    public toolbar: ToolbarItems[];
    @ViewChild('grid')
    public grid: GridComponent;
    public editSettings: EditSettingsModel;
    ngOnInit(): void {
        this.data = data;
        this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Normal' };
        this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel'];
    }
    load(args){
        this.grid.element.addEventListener('mouseup', (e: MouseEventArgs) => {
        if ((e.target as HTMLElement).classList.contains("e-rowcell")) {
        if (this.grid.isEdit)
            this.grid.endEdit();
            let index: number = parseInt((e.target as HTMLElement).getAttribute("Index"));
            this.grid.selectRow(index);
            this.grid.startEdit();
        };
        });
    }
}

Open dropdown edit popup on single click

You can open the default dropdown edit popup with single click edit by focusing the dropdown element and calling the EJ2 dropdown list’s showPopup method in the Grid’s actionComplete event. In this demo we have used a global flag variable in the mouseup event to ensure if the dropdown column is the clicked edit target.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { EditSettingsModel, ToolbarItems, GridComponent } from '@syncfusion/ej2-angular-grids';
import { MouseEventArgs } from '@syncfusion/ej2-base';
import { data } from './datasource';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid [dataSource]='data' [editSettings]='editSettings' [toolbar]='toolbar' allowPaging='true' (load)='load($event)' (actionComplete)='onActionComplete($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=100 isPrimaryKey='true'></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' width=120></e-column>
                    <e-column field='Freight' headerText='Freight' textAlign= 'Right' width=120 format= 'C2'></e-column>
                    <e-column field='ShipCountry' headerText='Ship Country' editType='dropdownedit' width=150></e-column>
                </e-columns>
                </ejs-grid>`
})

export class AppComponent implements OnInit {

    public data: object[];
    public toolbar: ToolbarItems[];
    @ViewChild('grid')
    public grid: GridComponent;
    public editSettings: EditSettingsModel;
    public isDropdown = false;

    ngOnInit(): void {
        this.data = data;
        this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true, mode: 'Normal' };
        this.toolbar = ['Add', 'Edit', 'Delete', 'Update', 'Cancel'];
    }
    load(args){
        this.grid.element.addEventListener('mouseup', (e: MouseEventArgs) => {
            if ((e.target as HTMLElement).classList.contains("e-rowcell")) {
              if (this.grid.isEdit)
                  this.grid.endEdit();
              let rowInfo = this.grid.getRowInfo(e.target);
              if (rowInfo.column.field === "ShipCountry")
                  this.isDropdown = true;
              this.grid.selectRow(rowInfo.rowIndex);
              this.grid.startEdit();
            }
        });
    }

    onActionComplete(args) {
        if (args.requestType =="beginEdit" && this.isDropdown) {
            this.isDropdown = false;
            let dropdownObj = args.form.querySelector('.e-dropdownlist').ej2_instances[0];
            dropdownObj.element.focus();
            dropdownObj.showPopup();
        }
    }
