C# Winform Button, make the border thicker and different color?

I have a Button that when clicked I would like to change the color of the button as well as the thickness of the border.   Is that possible?

thanks!

It is possible if you subclass the control and handle the paint event manually. Here is the crudest of examples to get you started.
    public class MyButton : Button
    {
        private bool _isClicked = false;

        protected override void OnPaint(PaintEventArgs pevent)
        {
            base.OnPaint(pevent);
            if (_isClicked)
            {
                pevent.Graphics.FillRectangle(Brushes.Red, this.ClientRectangle);
            }
        }

        protected override void OnClick(EventArgs e)
        {
            base.OnClick(e);
            this._isClicked = true;
        }
    }

Open in new window

You would still need to draw the border and text to make it look right.

How do I do it only when it is clicked?

That's what overriding the OnClick method is for and the private member _isClicked.

We would simply subscribe to the click event.  But also realize that the button border color and size are only shown when the button style is flat; e.g. -

Form1.cs -
using System;
using System.Drawing;
using System.Windows.Forms;

namespace EE_Q28976870
{
	public partial class Form1 : Form
	{
		public Form1()
		{
			InitializeComponent();
			button1.FlatAppearance.BorderColor = Color.Black;
			button1.FlatAppearance.BorderSize = 1;
		}

		private void OnClick(object sender, EventArgs e)
		{
			if (sender is Button)
			{
				var btn = sender as Button;
				if (btn.Equals(button1))
				{
					if (btn.FlatAppearance.BorderColor.Equals(Color.Black))
					{
						btn.FlatAppearance.BorderColor = Color.Blue;
						btn.FlatAppearance.BorderSize = 12;
						btn.FlatStyle = FlatStyle.Flat;
					}
					else
					{
						btn.FlatAppearance.BorderColor = Color.Black;
						btn.FlatAppearance.BorderSize = 1;
						btn.FlatStyle = FlatStyle.Standard;
					}
				}
			}
		}
	}
}

Open in new window

Form1.Designer.cs -
namespace EE_Q28976870
{
	partial class Form1
	{
		/// <summary>
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.IContainer components = null;

		/// <summary>

		/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
		protected override void Dispose(bool disposing)
		{
			if (disposing && (components != null))
			{
				components.Dispose();
			}
			base.Dispose(disposing);
		}

		#region Windows Form Designer generated code

		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
		{
			this.button1 = new System.Windows.Forms.Button();
			this.SuspendLayout();
			// 
			// button1
			// 
			this.button1.Font = new System.Drawing.Font("Microsoft Sans Serif", 22F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
			this.button1.Location = new System.Drawing.Point(42, 81);
			this.button1.Name = "button1";
			this.button1.Size = new System.Drawing.Size(200, 99);
			this.button1.TabIndex = 1;
			this.button1.Text = "Click\r\nMe!!!";
			this.button1.UseVisualStyleBackColor = true;
			this.button1.Click += new System.EventHandler(this.OnClick);
			// 
			// Form1
			// 
			this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
			this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
			this.ClientSize = new System.Drawing.Size(284, 261);
			this.Controls.Add(this.button1);
			this.Name = "Form1";
			this.Text = "Form1";
			this.ResumeLayout(false);

		}

		#endregion

		private System.Windows.Forms.Button button1;

	}
}

Produces the following output -
