C# MetroFramework - MetroComboBox - Fill from a Generic List

March 15, 2018 Oclemy C# ComboBox, C# Generic List 1 minute, 41 seconds

In this class we see how to populate a metrocombobox from a generic List.

MetroComboBox allows us display data in a dropdown manner, thus allowing users to select one item at a time.

When the user does that we handle the IndexSelectionChanged event thus displaying a messagebox.

Example Demo

Let's start.

1. Create Empty Project

  1. Open up Visual Studio and proceed over to File --> New Project

  2. A new dialog popus up like this:

Create Project

  1. Give our empty project a name and click OK. An empty project will get generated for us.

2. Install Metro Framework

If you haven't installed it yet. If you have then just add reference dlls to your project.

  1. Right click the references section of your project and select manage nuget packages.A dialog popups up.

  2. Search "Metro Framework" by Dennis Magno and click install as below.

Install MetroFramewok

3. Add Metro Framework DLLs to Project

We now need to add metro framework dlls to our project to use metro framework.

  1. Next right click the references section of your project and add the metroframework dlls from the packages directory onto which they were installed. You may need to search that directory in your computer.

Add MetroFramewok DLLs

  1. You should have it like these:

MetroFramewok References

4. Make project a Windows Project

Just right click on your project choose properties and set output type to Windows Application:

MetroFramewok References

5. Program.cs

We have one class, Program.cs.

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
using MetroFramework.Controls;
using MetroFramework.Forms;

namespace MetroComboBoxList
{
    static class Program
    {
        private static MetroComboBox metroComboBox;
        public static void Main()
        {
            MetroForm myForm = new MetroForm
            {
                Text = "MetroComboBox Generic List Example",
                ClientSize = new Size(564, 420)
            };

            metroComboBox = new MetroComboBox { Location = new Point(164, 176) };
            List<String> nebulae = new List<string> { "Horse Head", "Black Widow", "Ghost Head", "Cat's Eye","Elephant's Trunk", "Helix", "Rosette", "Ant", "Orion", "Butterfly", "Eagle", "Own", "Ring", "Pelican","Cone","Flame", "Witch Head", "Bumerang" };

            metroComboBox.DataSource = nebulae;

            metroComboBox.SelectedIndexChanged += metroComboBox_SelectedIndexChanged;

            myForm.Controls.Add(metroComboBox);
            Application.Run(myForm);
        }

        static void metroComboBox_SelectedIndexChanged(object sender, EventArgs e)
        {
            MessageBox.Show(metroComboBox.SelectedItem.ToString());
        }
    }
}

Best Regards, Oclemy.
