Gets or sets the border style for the spin box (also known as an up-down control).
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can use the BorderStyle property to create borderless and flat controls in addition to the default three-dimensional control.
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.
