Columns

The column definitions are used as the dataSource schema in the Grid. This plays a vital role in rendering column values in the required format. The grid operations such as sorting, filtering and grouping etc. are performed based on column definitions. The field property of the columns is necessary to map the data source values in Grid columns.

  1. If the column with field is not in the dataSource, then the column values will be displayed as empty.
  2. If the field name contains “dot” operator then it is considered as complex binding.

Auto generation

The columns are automatically generated when columns declaration is empty or undefined while initializing the grid. All the columns in the dataSource are bound as grid columns.

App.tsx
import { GridComponent } from '@syncfusion/ej2-react-grids';
import * as React from 'react';

const data: object[] = [
  { OrderID: 10248, CustomerID: 'VINET', EmployeeID: 5 },
  { OrderID: 10249, CustomerID: 'TOMSP', EmployeeID: 6 },
  { OrderID: 10250, CustomerID: 'HANAR', EmployeeID: 4 }];

export default class App extends React.Component<{}, {}>{
  public render() {
      return <GridComponent dataSource={data}/>
  }
}

Set Primary key column for auto generated columns when editing is enabled

Primary key can be defined in the declaration of column object of the grid. When we didn’t declare the columns, the grid will generate the columns automatically. For these auto generated columns, you can set isPrimaryKey column property as true by using the following ways,

If Primary key “column index” is known then refer the following code example

App.tsx
import { ColumnModel, Edit, EditSettingsModel, Grid, GridComponent, Inject } from '@syncfusion/ej2-react-grids';
import * as React from 'react';

const data: object[] = [
  { OrderID: 10248, CustomerID: 'VINET', EmployeeID: 5 },
  { OrderID: 10249, CustomerID: 'TOMSP', EmployeeID: 6 },
  { OrderID: 10250, CustomerID: 'HANAR', EmployeeID: 4 }];

export default class App extends React.Component<{}, {}>{
  public grid: Grid | null;
  public editOptions: EditSettingsModel = {
    allowAdding: true, allowDeleting: true, allowEditing: true
  };
  public dataBound(){
    if (this.grid) {
      const column: ColumnModel = this.grid.columns[0] as ColumnModel;
      column.isPrimaryKey = true;
    }
  }
  public render() {
      this.dataBound = this.dataBound.bind(this);
      return <GridComponent dataSource={data} dataBound= { this.dataBound }
                editSettings={this.editOptions} ref={g => this.grid = g}>
              <Inject services={[Edit]} />
             </GridComponent>
  }
}

If Primary key column and its field is known then primary key for the respective column can be defined as follows.

  const column: ColumnModel = this.grid.getColumnByField('OrderID');
  column.isPrimaryKey = true;

Set column options to auto generated columns

You can set column options such as format, width to the auto generated columns by using dataBound event of the grid.

In the below example, width is set for OrderID column, date type is set for OrderDate column and numeric type is set for Freight column.

App.tsx
import { ColumnModel, Grid, GridComponent } from '@syncfusion/ej2-react-grids';
import * as React from 'react';


const data: object = [
  { OrderID: 10248, CustomerID: 'VINET', Freight: 32.3800, OrderDate: "1996-07-02T00:00:00.000Z" },
  { OrderID: 10249, CustomerID: 'TOMSP', Freight: 32.3800, OrderDate: "1996-07-19T00:00:00.000Z" },
  { OrderID: 10250, CustomerID: 'HANAR', Freight: 32.3800, OrderDate: "1996-07-22T00:00:00.000Z" }];

export default class App extends React.Component<{}, {}>{
  public grid: Grid | null;
  public dataBound() {
    if (this.grid) {  
      const columns: ColumnModel[] = this.grid.columns as ColumnModel[];
      columns[0].width = 120;
      for (const col of columns) {
        if(col.field === "OrderDate"){
            col.type="date";
        }
        if (col.type === "date") {
            col.format = { type: "date", format: "dd/MM/yyyy" };
        }
        if (col.field === 'Freight') {
          col.format = "P2";
        }
      }
      this.grid.refreshColumns();
    }
  }
  public render() {
    this.dataBound = this.dataBound.bind(this);
    return <GridComponent dataSource={data} dataBound= { this.dataBound }
            ref={g => this.grid = g}/>
  }
}

Complex Data Binding

You can achieve complex data binding in the grid by using the dot(.) operator in the column.field.

For OData and ODataV4 adaptors, you need to add expand query to the query property (of Grid), to eager load the complex data.

import { DataManager, ODataAdaptor, Query } from '@syncfusion/ej2-data';
import { ColumnDirective, ColumnsDirective, GridComponent, Inject, Page } from '@syncfusion/ej2-react-grids';
import * as React from 'react';

export default class App extends React.Component<{}, {}>{
    public data: DataManager = new DataManager({
      adaptor: new ODataAdaptor ,
      crossDomain: true,
      url: 'https://js.syncfusion.com/demos/ejServices/Wcf/Northwind.svc/Orders'
    });
    public query = new Query().expand('Employee');
    public render() {
        return <GridComponent dataSource={this.data} query={this.query} height={315} allowPaging={true}>
                <Inject services={[Page]}/>
                <ColumnsDirective>
                    <ColumnDirective field='OrderID' headerText='Order ID' width='120' textAlign="Right"/>
                    <ColumnDirective field='CustomerID' headerText='Customer ID' width='150'/>
                    <ColumnDirective field='ShipCity' headerText='Ship City' width='150'/>
                    <ColumnDirective field='Employee.City' headerText='City Name' width='150'/>
                </ColumnsDirective>
               </GridComponent>
    }
}

Foreign Key Column

Foreign key column can be enabled by using column.dataSource, column.foreignKeyField and column.foreignKeyValue properties.

In the following example, Employee Name is a foreign column which shows FirstName column from foreign data.

You can autofit all columns, by invoking autoFitColumns method without column name.

Reorder

Reordering can be done by drag and drop of a particular column header from one index to another index within the Grid. To enable reordering, set the allowReordering to true.

To use reordering, inject the Reorder module in the grid.
