C# WinForms Button Image Switching Tutorial2 min read

Hello, everyone! Today, we’ll be discussing a clever solution to a common problem in Windows Forms applications. Have you ever wanted to dynamically change the image of a button without relying on image names at runtime? Well, you’re in the right place!

In this code snippet, we’ll explore how to seamlessly switch between two images for a button, improving user interaction. The secret lies in using global Bitmap objects to handle these changes.

C# Code:

To solve the button image change problem, we define two global Bitmap objects: bmpAccept and bmpReject. These images represent ‘Accept’ and ‘Reject’ actions.

In the Form1_Load event, we initially set the Image property of button1 to bmpAccept and change the button’s text to ‘Accept All.’ This is the default state when the form is loaded.

Now, let’s delve into the magic of the button1_Click event handler. When the user clicks the button, this code checks the current image of button1. If it’s bmpAccept, it changes the image to bmpReject and updates the text to ‘Reject All.’ If not, it reverts the image and text back to ‘Accept All’.

So, there you have it! This code provides an elegant solution to the issue of dynamically changing button images without needing image names. By using global Bitmap objects, we can seamlessly switch between ‘Accept All’ and ‘Reject All’ states based on user interaction.
