UpDownBase.BorderStyle Property


Gets or sets the border style for the spin box (also known as an up-down control).

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Property BorderStyle As BorderStyle

Property Value

Type: System.Windows.Forms.BorderStyle

One of the BorderStyle values. The default value is Fixed3D.

Exception Condition

The value assigned is not one of the BorderStyle values.

You can use the BorderStyle property to create borderless and flat controls in addition to the default three-dimensional control.

The following code example uses the derived class NumericUpDown and sets some of its properties derived from UpDownBase. This code requires that you have a NumericUpDown control named numericUpDown1, two ComboBox controls named comboBox1 and comboBox2, and three CheckBox controls named checkBox1, checkBox2, and checkBox2 created on a form. Add the following items to comboBox1: None, Fixed3D, and FixedSingle. Add the following items to comboBox2: Left, Right, and Center.

The code allows you to change the property values at run time and see how each affects the appearance and behavior of the spin box.

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
End Sub    

Private Sub checkBox1_Click(sender As Object, e As EventArgs)
    ' Evaluate and toggle the ReadOnly property.
    If numericUpDown1.ReadOnly Then
        numericUpDown1.ReadOnly = False
        numericUpDown1.ReadOnly = True
    End If
End Sub    

Private Sub checkBox2_Click(sender As Object, e As EventArgs)
    ' Evaluate and toggle the InterceptArrowKeys property.
    If numericUpDown1.InterceptArrowKeys Then
        numericUpDown1.InterceptArrowKeys = False
        numericUpDown1.InterceptArrowKeys = True
    End If
End Sub    

Private Sub checkBox3_Click(sender As Object, e As EventArgs)
    ' Evaluate and toggle the UpDownAlign property.
    If numericUpDown1.UpDownAlign = LeftRightAlignment.Left Then
        numericUpDown1.UpDownAlign = LeftRightAlignment.Right
        numericUpDown1.UpDownAlign = LeftRightAlignment.Left
    End If
End Sub
