CRUD Operation Using DevExtreme Table In React Js

In this article, we learn how to do CRUD operations using the DevExtreme table in react app.

First, need to all devextreme dependency and import all CSS files in App.js which are mentioned in the previous blog.

Now import the below dependency from the devextreme-react.

import DataGrid, {
  Column,
  Editing,
  Popup,
  Pager,
  Paging,
  Lookup,
  Form,
} from 'devextreme-react/data-grid';
import 'devextreme-react/text-area';
import { Item } from 'devextreme-react/form';

Then add DataGrid, Column, Pager, and Paging in App.js.

Now take the Lookup tag to show the dropdown data from the JSON file. That data looks like this,

export const states = [{
    ID: 1,
    Name: 'Alabama',
}, {
    ID: 2,
    Name: 'Alaska',
},
... 
];

For the edit functionality, we use the Editing tag, when we add and edit data that time we need to open the popup so we use the Popup tag, then we use the Form and Item tag for creating the form.

Now add some sample data to the JSON file.

export const employees = [{
    ID: 1,
    FirstName: 'John',
    LastName: 'Heart',
    Prefix: 'Mr.',
    Position: 'CEO',
    BirthDate: '1964/03/16',
    HireDate: '1995/01/15',
    Notes: 'John has been in the Audio/Video industry since 1990. He has led DevAv as its CEO since 2003.\r\n\r\nWhen not working hard as the CEO, John loves to golf and bowl. He once bowled a perfect game of 300.',
    Address: '351 S Hill St.',
    StateID: 5,
},
...
];

So, my App.js looks like this,

import React from 'react';
import './App.css';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';
import DataGrid, {
  Column,
  Editing,
  Popup,
  Pager,
  Paging,
  Lookup,
  Form,
} from 'devextreme-react/data-grid';
import 'devextreme-react/text-area';
import { Item } from 'devextreme-react/form';
import { employees, states } from './data.js';

const notesEditorOptions = { height: 100 };
const allowedPageSizes = [5, 10, "all"];

class App extends React.Component {
  render() {
    return (
      <div id="data-grid-demo">
        <DataGrid
          dataSource={employees}
          keyExpr="ID"
          showBorders={true}
        >
          <Editing
            mode="popup"
            useIcons={true}
            allowUpdating={true}
            allowAdding={true}
            allowDeleting={true}>
            <Popup title="Employee Info" showTitle={true} width={700} height={525} />
            <Form>
              <Item itemType="group" colCount={2} colSpan={2}>
                <Item dataField="FirstName" />
                <Item dataField="LastName" />
                <Item dataField="Prefix" />
                <Item dataField="BirthDate" />
                <Item dataField="Position" />
                <Item dataField="HireDate" />
                <Item
                  dataField="Notes"
                  editorType="dxTextArea"
                  colSpan={2}
                  editorOptions={notesEditorOptions} />
              </Item>

              <Item itemType="group" caption="Home Address" colCount={2} colSpan={2}>
                <Item dataField="StateID" />
                <Item dataField="Address" />
              </Item>
            </Form>
          </Editing>
          <Column dataField="Prefix" caption="Title" width={70} />
          <Column dataField="FirstName" />
          <Column dataField="LastName" />
          <Column dataField="BirthDate" dataType="date" />
          <Column dataField="Position" width={170} />
          <Column dataField="HireDate" dataType="date" />
          <Column dataField="StateID" caption="State" width={125}>
            <Lookup dataSource={states} valueExpr="ID" displayExpr="Name" />
          </Column>
          <Column dataField="Address" visible={false} />
          <Column dataField="Notes" visible={false} />
          <Paging defaultPageSize={10} />
          <Pager
            visible={true}
            allowedPageSizes={allowedPageSizes}
            displayMode="compact"
            showPageSizeSelector={true}
            showInfo={true}
            showNavigationButtons={true}
          />
        </DataGrid>
      </div>
    );
  }
}

export default App;
