NumericUpDownAcceleration Class

Note: This class is new in the .NET Framework version 2.0.

Provides information specifying how acceleration should be performed on a spin box (also known as an up-down control) when the up or down button is pressed for specified time period.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

The NumericUpDownAcceleration object is used by the NumericUpDown control to optionally provide acceleration when incrementing or decrementing the control through a large quantity of numbers.

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.

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);
       
}
