One of the LeftRightAlignment values. The default value is Right.

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.

                                             EventArgs e)
