That's why I set as the first and third the value 0 so no border will be drawn on the right and left side.

The parameters of ControlPaint.DrawBorder() for the rectangles width are as followed: In the method parameters for ControlPaint.DrawBorder() be aware of the 0 instead of the 2. private void label1_Paint(object sender, PaintEventArgs e)ĬontrolPaint.DrawBorder(e.Graphics, e.ClipRectangle,ĬontrolPaint.DrawBorder(e.Graphics, e.ClipRectangle, this.BackColor, ButtonBorderStyle.None) What simply has the color of the Form's Backcolor, so it seems like there isn't any border around label1. If we don't want to draw this special border, we draw a default border.

You can modify this border as you wish to. If so we use the ControlPaint class with it's DrawBorder() method to draw a custom border of the size of label1's Rectangle. Now we validate if a new special border shell be drawn or not. private void label1_MouseEnter(object sender, EventArgs e) In those events we will call label1.Refresh(), which redraws the control, so it's Paint() event will be fired. We change it's value in the MouseEnter() and MouseLeave() event. We will define a bool variable to check if a surroinding border shell be drawn around label1. So MouseEnter() is your preferred choice. Thats unnecessary because you will change the looking of label1 just when you enter the label and change it back to the default one, once you leave it. Since the hover event constantly fires while you are hovering label1. Label1.Font = new Font('Arial', 16, FontStyle.Bold) Īt first I suggest you to use the label1_MouseEnter() event instead of the label1_MouseHover() event. Private void label1_MouseLeave(object sender, EventArgs e) Label1.Font = new Font('Arial', 18, FontStyle.Bold) Label1.BorderStyle = BorderStyle.FixedSingle += new System.EventHandler(this.label1_MouseLeave) Ĭs: private void label1_MouseHover(object sender, EventArgs e) += new System.EventHandler(this.label1_MouseHover) I can't even change the color of the border, his width and more.ĭesigner.cs: = However, I only know how to define the normal border. Something similar to this: -> Border Transitions When the user will hover the label, it will add a top-border and bottom-border to the label.
