Example

[Visual Basic, C#, C++] The following example uses the derived class, NumericUpDown, and sets some of its properties derived from UpDownBase. This code assumes you have a NumericUpDown control, two ComboBox controls, and three CheckBox controls created on a form. Label the ComboBox controls: BorderStyle and TextAlign. Label the CheckBox controls: InterceptArrowKeys, ReadOnly, and UpDownAlign - Left. The code allows you to change the property values at run time and see how each affects the appearance and behavior of the up-down control. Add the following items to the combo box labled BorderStyle: None, Fixed3D, and FixedSingle items. Add the following items to the combo box labled TextAlign: Left, Right, and Center items.

[Visual Basic] 
Private Sub comboBox1_SelectedIndexChanged(sender As Object, e As EventArgs)
    ' Set the BorderStyle property.
    Select Case comboBox1.Text
        Case "Fixed3D"
            numericUpDown1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D
        Case "None"
            numericUpDown1.BorderStyle = System.Windows.Forms.BorderStyle.None
        Case "FixedSingle"
            numericUpDown1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle
    End Select
End Sub    

Private Sub comboBox2_SelectedIndexChanged(sender As Object, e As EventArgs)
    ' Set the TextAlign property.    
    Select Case comboBox2.Text
        Case "Right"
            numericUpDown1.TextAlign = HorizontalAlignment.Right
        Case "Left"
            numericUpDown1.TextAlign = HorizontalAlignment.Left
        Case "Center"
            numericUpDown1.TextAlign = HorizontalAlignment.Center
    End Select
