I'll create a Windows Forms version of the event management application using C#. This will be a desktop application that matches the layout and design from your reference image.

This Windows Forms application implements the event management interface from your reference image. Here's what the code does:

1. Program.cs: The entry point for the Windows Forms application.

2. MainForm.cs: Contains the form's logic and event handlers:

   • Populates the event list with sample data
   • Handles button clicks (Add Event, Reports, Delete, Edit)
   • Updates the right panel when an event is selected

3. MainForm.Designer.cs: Contains all the UI design code:

   • Creates a split container with left and right panels
   • Sets up the controls with the same colors and layout as your reference image
   • Configures the properties of each control (buttons, text boxes, list box)

4. Event.cs: A simple class to represent an event with properties for:

   • Id, Title, Date, Location, Description, and Participants

To run this application, you would:

1. Create a new Windows Forms project in Visual Studio
2. Add these files to your project
3. Build and run the application

The application matches the design from your reference image with:

• The beige/tan left panel with "Add Event" and "Reports" buttons and an event list
• The light blue-green right panel with fields for event details
• The same color scheme and layout as shown in your image

I'll modify the Windows Forms application to remove the panelRightSide panel. Here's the updated code for the MainForm.Designer.cs file:

I've made the following changes:

1. Removed the panelRightSide declaration from the class variables at the bottom of the file
2. Removed the initialization and setup of the panelRightSide panel
3. Added padding directly to splitContainer.Panel2 instead
4. Changed the control hierarchy to add all the controls that were previously in panelRightSide directly to splitContainer.Panel2

The functionality remains the same, but now the controls in the right panel are added directly to the splitContainer.Panel2 without the intermediate panelRightSide panel. This simplifies the control hierarchy while maintaining the same visual appearance and functionality.
