Mastering AG Grid Custom Tool Panel: Catching the Grid Ready Event

Are you tired of using the default tool panel in AG Grid? Do you want to take your data grid to the next level by creating a custom tool panel that meets your specific needs? Look no further! In this article, we’ll dive into the world of AG Grid custom tool panels and explore how to catch the grid ready event to get the most out of your grid.

What is AG Grid?

AG Grid is a popular JavaScript data grid library that provides a powerful and feature-rich grid component for building enterprise-level applications. With AG Grid, you can create complex data grids with ease, complete with features like filtering, sorting, grouping, and more.

What is a Custom Tool Panel?

A custom tool panel is a user-defined panel that can be added to the AG Grid to provide additional functionality or features. By creating a custom tool panel, you can tailor the grid to your specific needs and provide a more personalized experience for your users.

Why Catch the Grid Ready Event?

The grid ready event is an essential event in AG Grid that signifies when the grid has finished rendering and is ready for interaction. Catching this event is crucial when creating a custom tool panel, as it allows you to perform actions or initialize components once the grid is fully loaded.

By catching the grid ready event, you can:

• Initialize custom components or widgets
• Perform data manipulation or calculations
• Enable or disable grid features
• And more!

Creating a Custom Tool Panel

To create a custom tool panel, you’ll need to define a new component that will serve as the tool panel. For this example, we’ll create a simple React component that will display a button.

import React from 'react';

const CustomToolPanel = () => {
  return (
    

      Click me!
    
  );
};

export default CustomToolPanel;

Next, you’ll need to add the custom tool panel to the AG Grid by passing it as a property to the grid component.

import { AgGridReact } from 'ag-grid-react';
import CustomToolPanel from './CustomToolPanel';

const App = () => {
  return (
    

      
    
  );
};

Catching the Grid Ready Event

To catch the grid ready event, you can use the `onFirstDataRendered` prop provided by AG Grid. This prop is a callback function that will be executed once the grid has finished rendering and is ready for interaction.

import { AgGridReact } from 'ag-grid-react';
import CustomToolPanel from './CustomToolPanel';

const App = () => {
  const onFirstDataRendered = () => {
    console.log('Grid is ready!');
  };

  return (
    

      
    
  );
};

In the above example, the `onFirstDataRendered` callback function is executed once the grid has finished rendering, and it logs a message to the console indicating that the grid is ready.

Performing Actions on Grid Ready

Now that we’ve caught the grid ready event, we can perform actions or initialize components within the callback function. For example, let’s say we want to initialize a custom component within the tool panel once the grid is ready.

import { AgGridReact } from 'ag-grid-react';
import CustomToolPanel from './CustomToolPanel';

const App = () => {
  const onFirstDataRendered = () => {
    const toolPanel = document.querySelector('.ag-tool_panel');
    const customComponent = new CustomComponent(toolPanel);
    customComponent.init();
  };

  return (
    

      
    
  );
};

In the above example, we’re using the `onFirstDataRendered` callback function to initialize a custom component within the tool panel once the grid is ready.

Best Practices for Catching the Grid Ready Event

When catching the grid ready event, it’s essential to follow best practices to ensure that your code is efficient and reliable. Here are a few tips to keep in mind:

1. Use the `onFirstDataRendered` prop: This prop is specifically designed for catching the grid ready event, and it’s the recommended way to perform actions once the grid has finished rendering.
2. Avoid using setTimeout: Using `setTimeout` to delay the execution of code can lead to unexpected behavior and is generally considered a bad practice.
3. Keep your code concise: Try to keep your code concise and focused on the task at hand. Avoid performing complex operations within the `onFirstDataRendered` callback function.
