How to change Button's border colors?

Question

I'm new to Visual Basic and I want to change the border color of a Button, but I don't see any option to do that in the IDE (Visual Studio 2017). Is there a way to do this?

Solution 1

The way to do this is not very obvious as the default Button doesn't allow for a coloured border.

First you have to set the Button's FlatStyle property to FlatStyle.Flat. Then you have to set the Button's FlatAppearance.BorderColor property to the colour of your choice.

You can do both of those things in the Visual Studio form designer if you want, or you can do it in code like this:

Button1.Flatstyle = FlatStyle.Flat
Button1.FlatAppearance.BorderColor = Color.Yellow

Solution 2

You can do this is a few different ways. One option (quick and easy) is to subclass the System.Windows.Forms.Button class and then override the OnPaintmethod...

For example:

 Protected Overrides Sub OnPaint(ByVal pevent As System.Windows.Forms.PaintEventArgs)
        MyBase.OnPaint(pevent)
        Dim rect As New Rectangle(0, 0, Me.Width, Me.Height)
        Dim mPen As New Pen(Color.Red, 3)
        pevent.Graphics.DrawRectangle(mPen, rect)
    End Sub

Another option is to create your own button control, this takes time and you could benefit better as you would have more control in what you would like to do. If your button's FlatStyle property is set to "Flat" you could change the FlatApperance property in designer such as border-size and etc...

Button1.BorderColor = Drawing.Color.Red
