Question

我正在为我的Angular应用程序使用dataGrid小部件（来自DevExtreme lib）。

dataGrid运行良好，任何编辑操作都会自动保存。

我想取消此自动保存操作并将其替换为：

一个简单的按钮，单击时执行SAVE。

以下是代码：

app.component.ts

import { NgModule, Component, enableProdMode } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { DxDataGridModule } from 'devextreme-angular';
import { Customer, Service } from './app.service';

if(!/localhost/.test(document.location.host)) {
    enableProdMode();
}

@Component({
    styleUrls: ['app/app.component.css'],
    selector: 'demo-app',
    templateUrl: 'app/app.component.html',
    providers: [Service]
})
export class AppComponent {
    customers: Customer[];

    constructor(service: Service) {
        this.customers =  service.getCustomers();
    }
}

app.component.html

<dx-data-grid
    id="gridContainer"
    [dataSource]="customers"
    [columns]="['CompanyName', 'City', 'State', 'Phone', 'Fax']">
</dx-data-grid>

app.service.ts

import { Injectable } from '@angular/core';

export class Customer {
    ID: number;
    CompanyName: string;
    Address: string;
    City: string;
    State: string;
    Zipcode: number;
    Phone: string;
    Fax: string;
    Website: string;
}

let customers: Customer[] = [{

@Injectable()
export class Service {
    getCustomers() {
        return customers;
    }
}

有什么建议吗？

Answer 1

批量修改
如果您希望用户编辑多行，然后将所有更改保存在一起，则可以使用“批量编辑”功能。 DevExtreme中的功能。 Official Documentaion
添加dxo-editing标记，如此处所示

<dx-data-grid
    id="gridContainer"
    [dataSource]="customers"
    [columns]="['CompanyName', 'City', 'State', 'Phone', 'Fax']">

        <dxo-editing 
            mode="batch"
            [allowUpdating]="true">
        </dxo-editing>

</dx-data-grid>

逐行编辑
如果您希望用户一次只能编辑一行，则可以使用＆＃39;行编辑＆＃39; DevExtreme中的功能。 Official Documentation
添加dxo-editing标记，如此处所示

<dx-data-grid
    id="gridContainer"
    [dataSource]="customers"
    [columns]="['CompanyName', 'City', 'State', 'Phone', 'Fax']">

        <dxo-editing 
            mode="row"
            [allowUpdating]="true">
        </dxo-editing>

</dx-data-grid>
