Examples

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.

void comboBox1_SelectedIndexChanged( Object^ sender, EventArgs^ e )
{
   // Set the BorderStyle property.
   if (  !String::Compare( comboBox1->Text, "Fixed3D" ) )
   {

   }
   else
   if (  !String::Compare( comboBox1->Text, "None" ) )
   {
      numericUpDown1->BorderStyle = System::Windows::Forms::BorderStyle::None;
   }
   else

   {
      numericUpDown1->BorderStyle = System::Windows::Forms::BorderStyle::FixedSingle;
