UpDownAlign Property

UpDownBase.UpDownAlign Property

Gets or sets the alignment of the up and down buttons on 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 UpDownAlign As LeftRightAlignment

Property Value

Type: System.Windows.Forms.LeftRightAlignment
One of the LeftRightAlignment values. The default value is Right.


The value assigned is not one of the LeftRightAlignment values.

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
