Columns in JavaScript Grid control

18 May 2022 / 12 minutes to read

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.

If the column field is not specified in the dataSource, the column values will be empty.

If the field name contains “dot” operator, it is considered as complex binding.

Column types

Column type can be specified using the columns.type property. It specifies the type of data the column binds.

If the format is defined for a column, the column uses type to select the appropriate format option (number or date).

Grid column supports the following types:

string
number
boolean
date
datetime

If the type is not defined, it will be determined from the first record of the dataSource. Incase if the first record of the dataSource is null/blank value for a column then it is necessary to define the type for that column.

ValueAccessor

The valueAccessor is used to access/manipulate the value of display data. You can achieve custom value formatting by using the valueAccessor.

Display array type columns

You can bind an array of objects in a column by using the valueAccessor property. In this example, the name field has an array of two objects, FirstName and LastName. These two objects are joined and bound to a column using the valueAccessor.

By default, the number and date values are formatted in en-US locale. You can localize the currency and date in different locale as explained here

Number formatting

The number or integer values can be formatted using the below format strings.

Format	Description
N	Denotes numeric type.
C	Denotes currency type.
P	Denotes percentage type

Please refer to the link to know more about Number formatting.

Date formatting

You can format date values either using built-in date format string or custom format string.

For built-in date format you can specify columns.format property as string (Example: yMd). Please refer to the link to know more about Date formatting.

You can also use custom format string to format the date values. Some of the custom formats and the formatted date values are given in the below table.

Format	Formatted value
{ type:‘date’, format:‘dd/MM/yyyy’ }	04/07/1996
{ type:‘date’, format:‘dd.MM.yyyy’ }	04.07.1996
{ type:‘date’, skeleton:‘short’ }	7/4/96
{ type: ‘dateTime’, format: ‘dd/MM/yyyy hh:mm a’ }	04/07/1996 12:00 AM
{ type: ‘dateTime’, format: ‘MM/dd/yyyy hh:mm:ss a’ }	07/04/1996 12:00:00 AM

Customize column styles

You can customize the appearance of the header and content of a particular column using the customAttributes property.

To customize the grid column, follow the given steps:

Step 1:

Create a CSS class with custom style to override the default style for rowcell and headercell.

.e-grid .e-rowcell.customcss{
background-color: #ecedee;
color: 'red';
font-family: 'Bell MT';
font-size: 20px;
}

.e-grid .e-headercell.customcss{
background-color: #2382c3;
color: white;
font-family: 'Bell MT';
font-size: 20px;
}

Step 2:

Add the custom CSS class to the specified column by using the customAttributes property.

{ field: 'ShipCity', headerText: 'Ship City', customAttributes: {class: 'customcss'}, width: 100 },

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

let grid: Grid = new Grid({
dataSource: data,
enableHover: false,
allowSelection: false,
columns: [
    { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
    { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
    { field: 'ShipCity', headerText: 'Ship City', customAttributes: { class: 'customcss' }, width: 100 },
    { field: 'ShipName', headerText: 'Ship Name', width: 100 }
],
height: 315
});
grid.appendTo('#Grid');

#container {
    visibility: hidden;
}

#loader {
  color: #008cff;
  font-family: 'Helvetica Neue','calibiri';
  font-size: 14px;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

.e-grid .e-rowcell.customcss{
  background-color: #ecedee;
  font-family: 'Bell MT';
	color: red;
	font-size: 20px;
}

.e-grid .e-headercell.customcss{
  background-color: #2382c3;
  color: white;
	font-family: 'Bell MT';
	font-size: 20px;
}

To display a custom ToolTip (EJ2 Tooltip), you can render the Grid control inside the Tooltip component and set the target as “.e-rowcell”. The tooltip is displayed when hovering the grid cells.

Change the tooltip content for the grid cells by using the following code in the beforeRender event.

function beforeRender(args) {
  // event triggered before render the tooltip on target element.
  tooltip.content = args.target.closest("td").innerText;
}
