           myRB.Location = New Point(10, y)

           myRB.Text = "Candy " & x

Either store then when you create them in a list or array of RadioButtons (recommended) or you can find them via the Panel1.Controls array and iterate through:

VB

For Each c As Control In panel1.Controls
    Dim rb As RadioButton = TryCast(c, RadioButton)
    If rb IsNot Nothing Then
        If rb.Checked Then
            ' Handle checked button
            Exit For
        End If
    End If
Next

If you chose the second option, I would put a distinctive value into the Tag property, or you will have to check the Text to tell which one it is.
