custom checkbox and vertical text

custom checkbox and vertical text

custom checkbox and vertical text

(OP)
Because of screen real estate limitations, I thought checkboxes with vertical text would be useful and decided to give custom controls an inaugural attempt. Below is a simple control class: unfortunately it renders a proper checkbox graphic, but no visible text. I'd appreciate comments as to what I am overlooking or doing wrong.

CODE --> vb.net

Public Class VerticalCheckbox
    Inherits System.Windows.Forms.CheckBox

    Public Property VerticalText As String
    Private fmt As New StringFormat

    Public Sub New()
        fmt.Alignment = StringAlignment.Center
        fmt.FormatFlags = StringFormatFlags.DirectionVertical
    End Sub

    Public Shadows Property Text 'Overrides raiseserror
        Get
            Return _VerticalText
        End Get
        Set(ByVal value)
            _VerticalText = value
        End Set
    End Property

    Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
        MyBase.OnPaint(e)
        Dim cx As Single = (Left + Right) / 2
        Dim cy As Single = (Top + Bottom) / 2
        Dim g As Graphics = e.Graphics
          g.DrawString(_VerticalText, Font, Brushes.Black, New Rectangle(cx, cy, 100, 20), fmt)

    End Sub

End Class
