A NumericUpDown control contains a single numeric value that can be incremented or decremented by clicking the up or down buttons of the control. The user can also enter in a value, unless the ReadOnly property is set to true.

The numeric display can be formatted by setting the DecimalPlaces, Hexadecimal, or ThousandsSeparator properties. To display hexadecimal values in the control, set the Hexadecimal property to true. To display a thousands separator in decimal numbers when appropriate, set the ThousandsSeparator property to true. To specify the number of digits displayed after the decimal symbol, set the DecimalPlaces property to the number of decimal places to display.

To specify the allowable range of values for the control, set the Minimum and Maximum properties. Set the Increment value to specify the value to be incremented or decremented to the Value property when the user clicks the up or down arrow buttons. You can increase the speed that the control moves through numbers when the user continuously presses the up or down arrow by setting the Accelerations property.

When the UpButton or DownButton methods are called, either in code or by the click of the up or down buttons, the new value is validated and the control is updated with the new value in the appropriate format. Specifically, if the UserEdit property is set to true, the ParseEditText method is called prior to validating or updating the value. The value is then verified to be between the Minimum and Maximum values, and the UpdateEditText method is called.

Starting with the .NET Framework 2015, the NumericUpDown control will be resized based on the system DPI setting when the app.config file contains the following entry:

<appSettings>
  <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />
</appSettings>

The following code example creates and initializes a NumericUpDown control, sets some of its common properties, and allows the user to change some of these properties at run time. This code assumes three CheckBox controls have been placed on a form and handlers for their Click events have been instantiated. The DecimalPlaces, ThousandsSeparator, and Hexadecimal properties are set on the Click event of each check box.

    Public Sub InstantiateMyNumericUpDown()
        ' Create and initialize a NumericUpDown control.
        numericUpDown1 = New NumericUpDown()

        ' Dock the control to the top of the form.
        numericUpDown1.Dock = System.Windows.Forms.DockStyle.Top

        ' Set the Minimum, Maximum, and initial Value.
        numericUpDown1.Value = 5
        numericUpDown1.Maximum = 2500
        numericUpDown1.Minimum = - 100

        ' Add the NumericUpDown to the Form.
        Controls.Add(numericUpDown1)
    End Sub     

    ' Check box to toggle decimal places to be displayed. 
    Private Sub checkBox1_Click(sender As Object, e As EventArgs)
        ' If DecimalPlaces is greater than 0, set them to 0 and round the 
        ' current Value; otherwise, set DecimalPlaces to 2 and change the 
        ' Increment to 0.25.  
        If numericUpDown1.DecimalPlaces > 0 Then
            numericUpDown1.DecimalPlaces = 0
            numericUpDown1.Value = Decimal.Round(numericUpDown1.Value, 0)
        Else
            numericUpDown1.DecimalPlaces = 2
            numericUpDown1.Increment = 0.25D
        End If 
    End Sub     

    ' Check box to toggle thousands separators to be displayed. 
    Private Sub checkBox2_Click(sender As Object, e As EventArgs)
        ' If ThousandsSeparator is true, set it to false; 
        ' otherwise, set it to true.  
        If numericUpDown1.ThousandsSeparator Then
            numericUpDown1.ThousandsSeparator = False 
        Else
            numericUpDown1.ThousandsSeparator = True 
        End If 
    End Sub     

    ' Check box to toggle hexadecimal to be displayed. 
    Private Sub checkBox3_Click(sender As Object, e As EventArgs)
        ' If Hexadecimal is true, set it to false; 
        ' otherwise, set it to true.  
        If numericUpDown1.Hexadecimal Then
            numericUpDown1.Hexadecimal = False 
        Else
            numericUpDown1.Hexadecimal = True 
        End If 
    End Sub
