Examples

The following code example demonstrates how to use the NumericUpDownAcceleration class. To run this example, paste the following code into a form and call the InitializeAcceleratedUpDown method from the form's constructor or Load event handler. While the code is running, press and hold the up or down arrow to see the acceleration occur.

Visual Basic
Private numericUpDown1 As NumericUpDown

Private Sub InitializeAcceleratedUpDown() 
    numericUpDown1 = New NumericUpDown()
    numericUpDown1.Location = New Point(40, 40)
    numericUpDown1.Maximum = 40000
    numericUpDown1.Minimum = - 40000

    ' Add some accelerations to the control.
    numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(2, 100))
    numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(5, 1000))
    numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(8, 5000))
    Controls.Add(numericUpDown1)

End Sub
C#
private NumericUpDown numericUpDown1;
private void InitializeAcceleratedUpDown()
{
    numericUpDown1 = new NumericUpDown();
    numericUpDown1.Location = new Point(40, 40);
    numericUpDown1.Maximum = 40000;
    numericUpDown1.Minimum = -40000;

    // Add some accelerations to the control.
    numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(2,100));
    numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(5, 1000));
    numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(8, 5000));
    Controls.Add(numericUpDown1);
