How to Add Dynamic Buttons and TextBoxes with Events to an Excel Form

Are you looking to create a dynamic help form in Excel that allows users to click on various hyperlinks? If you're familiar with Excel's capabilities, you might already know that adding buttons and text boxes manually can be a tedious process, especially when you're dealing with a large number of items. In this guide, we’ll explore a way to automate this process using VBA (Visual Basic for Applications) to add buttons and textboxes with individual events attached to each button.

Understanding the Challenge

In the initial example, you might have realized that only the last button you created had an event handler attached to it. This happens because the code was designed to overwrite the event handler for each button during the loop. Therefore, when the loop completes, only the last button retains its event functionality.

The Solution

The solution to this challenge involves creating a collection of event handler classes. Here’s a breakdown of how you can achieve this:

Step 1: Define the Collection of Event Classes

Instead of having a single class to handle events for each button, we’ll create a collection to store instances of our event handling class.

Step 2: Modify the UserForm Code

Here’s the modified code that ensures each button retains its own unique event handling logic:

Step 3: Event Handling Class Definition

Ensure to have the following class defined where the event handlers are stored:

Explanation of the Code

Collections for Events: In the modified code, a new Collection called ButtonEvents is created to hold multiple instances of the C_events event handler class.

Dynamic Button Creation: The loop creates multiple buttons based on the hyperlinks defined in the arrHyperlinks array.

Individual Event Assignment: Each button has its event handler attached through an instance of C_events, ensuring that each button alerts the user with its corresponding caption when clicked.

Conclusion

With this approach, you can efficiently create a dynamic help form in Excel with multiple buttons and associate distinct event handlers with each button. By utilizing collections and class instances, you make your Excel application more interactive and user-friendly.

Now you can take the first step towards enhancing your Excel forms, making them more interactive and tailored to your users’ needs!
