How to Change Material UI IconButton Icon on Click in React

User interfaces often require dynamic interactions that enhance user experience, and one common interaction is changing an icon upon user input. If you're using Material-UI in your React application, you might find yourself asking: How can I change the icon inside an IconButton when it's clicked? This post provides a simple and effective way to achieve that.

The Problem

Imagine you have an IconButton within a DataGrid component, and you want it to switch between two icons based on user actions. The challenge here is managing the state effectively to determine which icon to display when the button is clicked.

The Solution

To solve this problem, we can utilize React's state management capabilities. By leveraging the useState hook, we can maintain a boolean state that toggles between true and false. Here’s how to do it step by step:

Step 1: Setting Up State Management

First, we need to declare a state variable to manage the icon state. We'll name our state active and use the setActive function to update its value.

Step 2: Assigning the OnClick Event

Next, we will implement the onClick event for our IconButton. In this function, we will toggle the active state and perform any other necessary function calls.

Step 3: Conditional Rendering of Icons

Now, we can determine which icon to display based on the active state. If active is true, we will show Icon1; otherwise, we will show Icon2.

Summary

By following the above steps, you can easily toggle between two icons for a Material UI IconButton upon user clicks. State management with useState in React allows you to create dynamic interfaces that react to user interactions seamlessly.

Key Takeaway

The most efficient way to handle multiple icon states in React with Material-UI involves using boolean states to toggle between two icons. This technique can enhance the interactivity of your applications.

Feel free to implement this in your projects, and watch your user interface come to life!
