You can only select one radio button from a group. If you want to have more than one group you need to put each group in a separate container. The form is one container. Other containers include groupBoxes and panels. In the program shown below, we have used groupBoxes to create two groups of buttons. The groupBox has text, the panel does not. Notice that we can select both a color and a shape.
Build the form as shown. It is important to put the groupBox on the form first, then draw the radioButtons inside the groupBox. Drag the groupBox. If the radioButton moves with it, it is inside the groupBox. If not, delete the radio button and try again. After creating the first groupBox you can copy and paste to create the second group.
This form has the following controls:
Write code as shown below:
'Programmer: Janet Joy 'Illustrate group boxes Public Class Form1 Private Sub Form1_MouseClick(sender As Object, e As MouseEventArgs) Handles Me.MouseClick Dim MyPen As New Pen(Color.Goldenrod, 3) If Me.RadBlue.Checked Then MyPen.Color = Color.Blue ElseIf Me.RadRed.Checked Then MyPen.Color = Color.Red End If If Me.RadCircle.Checked Then Me.CreateGraphics.DrawEllipse(MyPen, e.X, e.Y, 20, 20) Else Me.CreateGraphics.DrawRectangle(MyPen, e.X, e.Y, 20, 20) End If End Sub End Class
