Set the default properties back to your label in the `MouseLeave` event. — Salah Akbari, Dec 21 '17 at 12:07

What's mean that default value? Do you want label Text when clicked? — Metehan Senol, Dec 21 '17 at 12:08

You should use MouseEnter and MouseLeave event.

In MouseEnter set your "hover"-font. In MouseLeave reset to default font.

Label label = new Label();
label.Text = "Hello World!";
label.MouseEnter += label_MouseEnter;
label.MouseLeave += label_MouseLeave;

Example changes from Segoe UI 12 to 18 pixel

private void label_MouseEnter(object sender, EventArgs e)
{
    Label label = sender as Label;

    if(label != null)
    {
        label.Font = new Font("Segoe UI", 12, FontStyle.Bold, GraphicsUnit.Pixel);
    }
}
private void label_MouseLeave(object sender, EventArgs e)
{
    Label label = sender as Label;

    if (label != null)
    {
        label.Font = new Font("Segoe UI", 18, FontStyle.Bold, GraphicsUnit.Pixel);
    }
}

thanks alot it's work for me too , i found that i can use mouse hover and mouse leave events but thanks any way – Lubbock Dec 21 '17 at 12:27
You should use MouseEnter, because MouseHover fires multiple times, while moving Mouse over Control. MouseEnter only once. – Christian Edel Dec 21 '17 at 12:31
@chistian edel you mean every time the mouse over on label it's going to do code ? – Lubbock Dec 21 '17 at 12:36
Yes, MouseHover is described as follows: Occurs when the mouse pointer rests on the control. – Christian Edel Dec 21 '17 at 12:44

1 Use Control.MouseLeave event and in there Control.ResetFont() method

private void label1_MouseLeave(object sender, System.EventArgs e) { label1.ResetFont(); }
