Button button1  = new Button();
Color c = button1.BackColor;
button1.MouseEnter += new System.EventHandler(this.button1_MouseEnter);
button1.MouseLeave += new System.EventHandler(this.button1_MouseLeave);

private void button1_MouseEnter(object sender, System.EventArgs e) {
      this.button1.BackColor = Color.Red;
}

private void button1_MouseLeave(object sender, System.EventArgs e) {
      this.button1.BackColor = c;
}

1. Open Visual Studio 2005
2. Press CRTL-SHIFT-N
3. Under "Project Types" make sure C# is Selected.
4. Select the "Windows Application" Template
5. Under the name TextBox change "WindowsApplcation1.cs" to "ButtonColor.cs"
6. Make Sure "Create Directory for Solution" is checked.
7. Press the Ok Button.
8. Click on a Button so that is selected in your Toolbox then click your Windows Form
9.  Make sure the button on the form is selected and press CRTL-W-P to display the properties window
10. On top of the Properties Window there is a lightning bolt that represents Events for an object. Click it to see the events for the button.
11. The two events you need to use are MouseHover (or MouseEnter) and the MouseLeave Event. Double Click the empty space next to MouseHover.
12. You should have been taken to the code view and a new Event Handler is created. Enter the Code :   buton1.BackColor = Color.Red;
Your Code should look what I have below:

private void button1_MouseHover(object sender, EventArgs e)
        {
            button1.BackColor = Color.Red;
        }

13.  Press Shift-F7 So that you are back to Designer View
14.  Double-Click  on the empty space next to the MouseLeave event
15.  Back in code view under the newly created event for MouseLeave enter this code: button1.BackColor = SystemColors.ButtonFace;
Your Code should look like what I have below:
 private void button1_MouseLeave(object sender, EventArgs e)
        {
            button1.BackColor = SystemColors.ButtonFace;
        }

16. Press the F5 key to run your program and see if you get your desired results.
