How to Create a Material MessageBox in C#

To create a Material Design-style MessageBox in C#, you can utilize third-party libraries like MaterialSkin. Below is an example of how to create a Material Design MessageBox using the MaterialSkin library.

Create a new Windows Forms Application project, then nstall the MaterialSkin library via NuGet Package Manager.

You can do this by running the following command in the Package Manager Console:

Install-Package MaterialSkin

You can also install it from the Visual Stdio by right-clicking on your project, then select Manage NuGet Packages -> Enter 'material skin' at the search box -> install it.

install material skin

How to create a custom message box in C#?

You can create a custom message box using material skin by creating a new form, then rename it to frmOK

MessageBox OK: frmOK

You can drag and drop the material button, label control from the Visual Studio toolbox into your form designer.

c# material ok message box

Modify your layout as show above

Do the same way for YesNo MessageBox, create a new form then change name to frmYesNo

MessageBox Yes/No: frmYesNo

c# material yes no message box

And the Main Form, i just add 2 material buttons

c# material message box

To create a custom message box, i will create a MaterialMessageBox class to handle MessageBox as shown below.

// c# create a custom message box
public static class MaterialMessageBox
    public static DialogResult Show(string message, string caption, MessageBoxButtons button)
        DialogResult result = DialogResult.None;
        switch (button)
            case MessageBoxButtons.YesNo:
                using (frmYesNo yesNo = new frmYesNo())
                    yesNo.Text = caption;
                    yesNo.Message = message;
                    result = yesNo.ShowDialog();
            case MessageBoxButtons.OK:
                using (frmOK ok = new frmOK())
                    ok.Text = caption;
                    ok.Message = message;
                    result = ok.ShowDialog();
        return result;

Open your Main Form, then modify your code as shown below.

To create a material form you need to change the inheritance from Form to MaterialForm

using System.Windows.Forms;
using MaterialSkin;

// message box c#
namespace MaterialMessageBoxDemo
   // Form1 class represents the Material Design MessageBox form
    public partial class Form1 : MaterialSkin.Controls.MaterialForm
        MaterialSkin.MaterialSkinManager skinManager;
        public Form1()
            // c# init skin material form
            skinManager = MaterialSkinManager.Instance;
            skinManager.Theme = MaterialSkinManager.Themes.DARK;
            skinManager.ColorScheme = new ColorScheme(Primary.Green600, Primary.Grey600, Primary.Grey900, Accent.LightBlue200, TextShade.WHITE);
        // c# show message box
        private void materialRaisedButton1_Click(object sender, EventArgs e)
            if(MaterialMessageBox.Show("Are you sure want to delete this record?", "Message", MessageBoxButtons.YesNo) == DialogResult.Yes)

        private void materialRaisedButton2_Click(object sender, EventArgs e)
            MaterialMessageBox.Show("Thank you for watching this video !", "Message", MessageBoxButtons.OK);

This code will create a Material Design-style MessageBox with a specified message, title, and buttons. You can extend it further to handle different types of MessageBox buttons or customize its appearance according to your needs.
