ADDING CUSTOM CELL EDITOR
AG-Grid (Ag-Grid) is a powerful JavaScript library for creating data grids in web applications. It provides extensive features for data manipulation, including sorting, filtering, and editing. While AG-Grid offers a range of built-in cell editors, there are times when you need to customize the editing experience to meet specific project requirements. In this blog post, we will explore how to add a custom cell editor to AG-Grid, allowing you to tailor the editing behavior to your needs
Prerequisites
Before we begin, ensure that you have the following prerequisites:
A basic understanding of JavaScript and React (though you can use ag-Grid with other frameworks or plain JavaScript).
An ag-Grid project set up. If you haven’t already, you can install it via npm or yarn:
Why Customize Cell Editors?
Custom cell editors in AG-Grid can be incredibly valuable for several reasons:
Unique Data Types: Sometimes, your data may contain unique or complex data types that AG-Grid’s default editors cannot handle adequately. Custom editors allow you to create specialized editors for these data types.
Enhanced User Experience: You might want to create a more user-friendly and intuitive editing interface that aligns with your application’s design and user experience guidelines.
Advanced Validation and Formatting: Implement sophisticated validation and formatting logic during data input to ensure data integrity and consistency.
Let’s get started with adding a custom cell editor to AG-Grid in a React application.
1. Set Up Your ag-Grid Component:
Start by creating or locating the component where you’ve integrated ag-Grid. For this example, let’s assume you have a component named GridComponent.js.
2. Define the Custom Cell Editor:
You can create your custom cell editor as a React component. In this example, we’ll create a simple text editor.
this example, we created a simple TextEditor component that renders a text input. The useImperativeHandle hook is used to expose a getValue function, which will retrieve the edited value.
- 3. Integrate the Custom Cell Editor with ag-Grid:
Now, you need to integrate the TextEditor component into your ag-Grid setup. In your GridComponent.js, make sure you’ve imported the necessary ag-Grid modules.

// GridComponent.js import React from 'react'; import { AgGridReact } from 'ag-grid-react'; import 'ag-grid-community/styles/ag-grid.css'; import 'ag-grid-community/styles/ag-theme-alpine.css'; import TextEditor from './TextEditor'; const GridComponent = () => { const columnDefs = [ // Define your column definitions here { headerName: 'Custom Edit', field: 'customEditField', cellEditor: 'textEditor', }, ]; const gridOptions = { frameworkComponents: { textEditor: TextEditor, }, }; return ( <div className="ag-theme-alpine" style={{ height: 400, width: 600 }}> <AgGridReact columnDefs={columnDefs} rowData={yourData} gridOptions={gridOptions} /> </div> ); }; export default GridComponent; |
In this example, we’ve added a column definition that uses the TextEditor component as a custom cell editor. We’ve also set up gridOptions to define the frameworkComponents, which maps the editor to the ‘textEditor’ string.
Handle the Edited Value:
When the user edits a cell, ag-Grid will use the getValue method from your TextEditor component to retrieve the edited value. You can handle this edited value in your application logic.
Customize and Style:
Customize the TextEditor component to match your application’s requirements and styling.
Implementing Custom Sorting
Custom sorting in ag-Grid involves creating a custom sorting algorithm and integrating it into the ag-Grid configuration.
Step 1: Define a Custom Sorting Algorithm
Let’s create a simple custom sorting algorithm that sorts strings based on their length.
|
1 2 3 4 5 6 7 8 |
export const customSort = (a, b) => { const lengthA = a.length; const lengthB = b.length; if (lengthA === lengthB) { return 0; } return lengthA < lengthB ? -1 : 1; }; |
Step 2: Integrate Custom Sorting into ag-Grid
Now, let’s integrate the custom sorting algorithm into ag-Grid for a specific column.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
import React from ‘react’; import { AgGridReact } from ‘ag-grid-react’; import ‘ag-grid-community/dist/styles/ag-grid.css’; import ‘ag-grid-community/dist/styles/ag-theme-alpine.css’; import { customSort } from ‘./CustomSort’; // Import the custom sort function const YourComponent = () => { const columnDefs = [ { headerName: ‘Name’, field: ‘name’, // Add the custom sort function to the column definition comparator: customSort, }, { headerName: ‘Age’, field: ‘age’ }, // … other column definitions ]; const rowData = [ { name: ‘John Doe’, age: 30 }, { name: ‘Jane Smith’, age: 25 }, // … other row data ]; return ( <div className=“ag-theme-alpine” style={{ height: ‘300px’, width: ‘600px’ }}> <AgGridReact columnDefs={columnDefs} rowData={rowData} /> </div> ); }; export default YourComponent; In this step, we've added the comparator property to the column definition and assigned it the custom sort function (customSort). The comparator property allows us to specify a custom comparison function for sorting. |
Step 3: Testing the Custom Sorting
Run your React application, and you’ll see that the “Name” column is sorted based on string length using the custom sorting logic defined in customSort.
CONCLUSION
In conclusion, enhancing AG Grid with custom functionality is a powerful way to tailor data grids to specific application needs. AG Grid, being a robust JavaScript data grid library, offers a versatile platform for developers to extend and enrich its capabilities according to unique project requirements.
By integrating custom functionalities, developers can introduce specialized features, data processing methods, sorting algorithms, and interactive elements. This empowers applications to handle diverse data sets and present them in a manner that best suits the intended user experience.
Whether it’s custom sorting, filtering, grouping, or implementing bespoke data manipulation, AG Grid’s flexible architecture allows developers to seamlessly incorporate these functionalities. This flexibility ensures that the grid not only meets basic data presentation needs but also goes beyond to fulfill complex business requirements.
Furthermore, the ability to create custom renderers and editors in AG Grid enables developers to present data in a highly intuitive and visually appealing way. This not only improves user engagement but also adds significant value to the application by offering a rich and interactive data viewing experience.
In essence, custom functionality in AG Grid empowers developers to optimize the grid for their specific use cases, making it an indispensable tool for building feature-rich and highly performant applications. It’s a testament to the flexibility and extensibility that AG Grid offers, making it a popular choice among developers seeking to create exceptional data-driven web applications.
