Column template in EJ2 JavaScript Grid control

14 May 202424 minutes to read

Grid control provides a template option that allows you to display custom elements in a column instead of the field value. This can be useful when you need to display images, buttons, or other custom content within a column.

When using template columns, they are primarily meant for rendering custom content and may not provide built-in support for grid actions like sorting, filtering, editing. It is must to define the field property of the column to perform any grid actions.

Render image in a column

To render an image in a grid column, you need to define a template for the column using the template property. The template property expects the HTML element or a function that returns the HTML element.

The following example demonstrates how to define a template for the Employee Image field that displays an image element. The template property is set to the HTML element that contains an image tag. You have utilized the src and alt attributes to an image tag.

var grid = new ej.grids.Grid({
    dataSource: employeeData,
    columns: [
        {
            headerText: 'Employee Image', textAlign: 'Center',
            template: '#template', width: 150
        },
        { field: 'FirstName', headerText: 'First Name', width: 100 },
        { field: 'LastName', headerText: 'Last Name', width: 100 },
        { field: 'City', headerText: 'City', width: 100 }
    ],
    height: 315
});
grid.appendTo('#Grid');

The template option allows to define any HTML content within a column.

The Grid control provides support for rendering hyperlink columns and performing routing on click using the template property. This feature is useful when displaying data that requires a link to another page or website.

The following example demonstrates, how to render hyperlink column in the Grid using the template property of the column. To define a template for the column, you can use the template with the a tag to create the hyperlink.

var grid = new ej.grids.Grid({
    dataSource: employeeData,
    columns: [
        { field: 'EmployeeID', headerText: 'Employee ID', width: 90 },
        { field: 'LastName', headerText: 'Last Name', width: 150 },
        { field: 'FirstName', headerText: 'First Name', width: 150, template: '#template' }
    ],
    height: 315
});
grid.appendTo('#Grid');

The window.open() method is a built-in JavaScript function that opens a new browser window or tab with the specified URL.

Render other controls in a column

The column template has options to render a custom control in a grid column instead of a field value.

Render LineChart control in a column

The LineChart control of Syncfusion provides an elegant way to represent and compare data over time. It displays data points connected by straight line segments to visualize trends in data.

In the following example, we have rendered the Sparkline Chart control in the Grid column by defining the template property.

var grid = new ej.grids.Grid({
    dataSource: employeeData,
    queryCellInfo: queryCellInfo,
    columns: [
        { field: 'EmployeeID',headerText: 'Employee ID',textAlign: 'Right',width: 90},
        { field: 'FirstName', headerText: 'First Name', width: 150 },
        { headerText: 'Employee Performance Rating', template: '#columnTemplate', width: 280 }

    ],
    height: 315,
});
grid.appendTo('#Grid');

var lineData = [
  [0, 6, -4, 1, -3, 2, 5],
  [5, -4, 6, 3, -1, 2, 0],
  [6, 4, 0, 3, -2, 5, 1],
  [4, -6, 3, 0, 1, -2, 5],
  [3, 5, -6, -4, 0, 1, 2],
  [1, -3, 4, -2, 5, 0, 6],
  [2, 4, 0, -3, 5, -6, 1],
  [5, 4, -6, 3, 1, -2, 0],
  [0, -6, 4, 1, -3, 2, 5],
  [6, 4, 0, -3, 2, -5, 1],
];

function queryCellInfo(args) {
  if (args.column.headerText === 'Employee Performance Rating') {
    var sparklineContainer = args.cell.querySelector('#spkline' + args.data.EmployeeID);
    var line = new ej.charts.Sparkline({
      height: '50px',
      width: '90%',
      lineWidth: 2,
      valueType: 'Numeric',
      fill: '#3C78EF',
      dataSource: getSparkData('line', args.data.EmployeeID),
    });
    line.appendTo(sparklineContainer);
  }
}

  function getSparkData( type, count ) {
    return lineData[count];
  }

Render ColorPicker control in a column

The ColorPicker control of Syncfusion provides a user-friendly way to select colors from a pre-defined color palette or custom colors. It can be used in a variety of scenarios such as picking a theme color or changing the color of an element on a page.

In the following code, we rendered the ColorPicker control in the Grid column by defining the template property.

function colorPicker(args: QueryCellInfoEventArgs) {
  let inputElement: HTMLSelectElement  = args.cell.querySelector('input')
    let colorPickerObject: ColorPicker = new ColorPicker({
      type: 'color',
      mode: 'Palette',
      change: change,
    });
    colorPickerObject.appendTo(inputElement);
}
var grid = new ej.grids.Grid({
    dataSource: employeeData,
    enableHover: false,
    queryCellInfo: colorPicker,
    columns: [
      { field: 'FirstName', headerText: 'First Name', textAlign: 'Right', width: 90 },
      { field: 'LastName', headerText: 'Last Name', width: 150 },
      { field: 'City', headerText: 'City', width: 150 },
      { headerText: 'Change the color of row', template: '#columnTemplate', width: 120 },
    ],
    height: 315,
});
grid.appendTo('#Grid');

function colorPicker(args) {
  var inputElement = args.cell.querySelector('input')
    var colorPickerObject = new ej.inputs.ColorPicker({
      type: 'color',
      mode: 'Palette',
      change: change,
    });
    colorPickerObject.appendTo(inputElement);
  }

function change(args) {
  var selectedRows = grid.getSelectedRows(); 
  for (var row of selectedRows) {
    row.style.backgroundColor = args.value ;
}
  grid.clearSelection();
}

Render DropDownList control in a column

To render a custom control in a grid column, you need to define a template for the column using the template property. In the following code, we rendered the DropDownList control in the Order Status column by defining the template property.

    function dropdown(args: QueryCellInfoEventArgs) {
        let element=args.cell.querySelector('select');
        let dropdownObject = new DropDownList({popupHeight: 150, popupWidth: 150});
        dropdownObject.appendTo(element);
    }
var grid = new ej.grids.Grid({
    dataSource: data,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 90 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 100 },
        { field: 'Freight', headerText: 'Freight', width: 90, format: 'C2' },
        { headerText: 'Order Status',
          template:
            `<div>
                <select class="e-control e-dropdownlist">
                    <option value="1" selected="selected">Order Placed</option>
                    <option value="2">Processing</option>
                    <option value="3">Delivered</option>
                </select>
            </div>`, width: 200
        },
    ],
    height: 315,
    queryCellInfo: dropdown
});
grid.appendTo('#Grid');

function dropdown(args) {
    var element = args.cell.querySelector('select');
    var dropdownObject = new ej.dropdowns.DropDownList({ popupHeight: 150, popupWidth: 150 });
    dropdownObject.appendTo(element);
}

Render Chip control in a column

The Grid control provides support for rendering Chips control in a column using the template property. This feature is useful when displaying data that requires a chip control to be rendered in a column.

In the following code, we rendered the Chips control in the Grid First Name column by defining the template property.

  function queryCellInfo(args: QueryCellInfoEventArgs ) {
      if (args.column.field === 'FirstName') {
      var chip = new ChipList({
        text: args.data[args.column.field],
      });
      chip.appendTo(args.cell.querySelector('#chipElement'));
    }
  }
var grid = new ej.grids.Grid({
    dataSource: employeeData,
    enableHover: false,
    queryCellInfo: queryCellInfo,
    columns: [
      { field: 'LastName', headerText: 'Last Name', width: 90 },
      { field: 'City', headerText: 'City', width: 150 },
      { field: 'FirstName', headerText: 'First Name', template: '#columnTemplate', width: 90 },
    ],
    height: 315,
});
grid.appendTo('#Grid');

function queryCellInfo(args) {
  if (args.column.field === 'FirstName') {
    var chip = new ej.buttons.ChipList({
      text: args.data[args.column.field],
    });
    chip.appendTo(args.cell.querySelector('#chipElement'));
  }
}

Using condition template

The conditional column template allows you to display template elements based on specific conditions.

The following example demonstrates how to use the template property with the template element and add the condition to render the checkbox based on the value of the Discontinued field. The Discontinued field will render a checkbox in each row for which the value of the Discontinued field is true.

  <script id="template" type="text/x-template">
            <div class="template_checkbox">
                ${if(Discontinued)}
                <input type="checkbox" checked> ${else}
                <input type="checkbox"> ${/if}
            </div>
        </script>
var grid = new ej.grids.Grid({
    dataSource: categoryData,
    columns: [
            {
                headerText: 'Discontinued', textAlign: 'Center',
                template: '#template', width: 150
            },
            { field: 'ProductID', headerText: 'Product ID', textAlign: 'Right', width: 150 },
            { field: 'CategoryName', headerText: 'Category Name', width: 150 },
            { field: 'ProductName', headerText: 'Product Name', width: 150 }
        ],
    height: 315
});
grid.appendTo('#Grid');

You can use any template element or custom control instead of the checkbox in the conditional template based on your requirement.

How to get the row object by clicking on the template element

The Grid control allows you to retrieve the row object of the selected record when clicking on a template element. This feature can be useful when you need to perform custom actions based on the selected record.

In the following code, the button element is rendered in the Employee Data column and click event binding is used to call the showDetails method when the template element is clicked. The showDetails method is passed the data object as an argument, which allows you to access the selected row object and display it in the dialog popup.

var grid = new ej.grids.Grid({
    dataSource: employeeData,
    queryCellInfo: queryCellInfo,
    columns: [
      { field: 'EmployeeID', headerText: 'Employee ID', textAlign:'Right', width: 130 },
      { field: 'FirstName', headerText: 'First Name', width: 120 },
      { field: 'Employee Data', headerText: 'Employee Data', textAlign:'Right', template: '#columnTemplate', width: 150, isPrimaryKey: true },
    ],
    height: 315,
});
grid.appendTo('#Grid');

function queryCellInfo(args) {
  if (args.column.headerText === 'Employee Data') {
    args.cell.querySelector('#button').addEventListener('click', (e) => {
      dialog.visible = true
      dialog.content =
        `<p><b>EmployeeID:</b> ${args.data.EmployeeID}</p>
         <p><b>FirstName:</b> ${args.data.FirstName}</p>
         <p><b>LastName:</b> ${args.data.LastName}</p>`
    })
  }
}

var dialogVisible = false;

var dialog = new ej.popups.Dialog({
  header: "Selected Row Details",
  content: "dialogContent",
  showCloseIcon: true,
  width: "50%",
  visible: dialogVisible
})
dialog.appendTo('#dialog');

Use custom helper inside the template

The Syncfusion Grid allows you to use custom helpers inside the template property of a column. This feature allows you to create complex templates that can incorporate additional helper functions that are not available through the default template syntax.

To use the custom helper function inside a column template, you must first add the function to the template’s context.

The following example demonstrates how to use a custom helper function inside the template property, using the template element for the Freight column.

var grid = new ej.grids.Grid({
    dataSource: data,
    columns: [
      { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 90 },
      { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
      { field: 'Freight', headerText: 'Freight', template: '#template', textAlign: 'Right', format: 'C2', width: 90 },
      { field: 'OrderDate', headerText: 'Order Date', textAlign: 'Right', format: 'yMd', width: 120 }
    ],
    height: 315,
});
grid.appendTo('#Grid');

Custom helpers can only be used inside the template property of a column.
