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" ) )
   {
      numericUpDown1->BorderStyle = System::Windows::Forms::BorderStyle::Fixed3D;
   }
   else
   if (  !String::Compare( comboBox1->Text, "None" ) )
   {
      numericUpDown1->BorderStyle = System::Windows::Forms::BorderStyle::None;
   }
   else
   if (  !String::Compare( comboBox1->Text, "FixedSingle" ) )
   {
      numericUpDown1->BorderStyle = System::Windows::Forms::BorderStyle::FixedSingle;
   }
}

void comboBox2_SelectedIndexChanged( Object^ sender, EventArgs^ e )

   if (  !String::Compare( comboBox1->Text, "Left" ) )
   {

   }
   else
   if (  !String::Compare( comboBox1->Text, "Center" ) )
   {
      numericUpDown1->TextAlign = HorizontalAlignment::Center;
   }
}

Remarks

A spin box consists of a text box and a small vertical scroll bar, commonly referred to as a spin button control. The UpDownBase class links the two controls and allows the user to change the display in the text box by clicking the up or down buttons or by entering the appropriate type of value directly into the text box. Use the spin box in cases where you want to limit the list of values a user can select, similar to a list box or combo box. Depending upon the type of list you want to display, the advantage to using a spin box is that it allows you to quickly set a range of valid values, rather than adding items one at a time. Implementing a spin box requires less data validation than a text box, as you can limit the data type when you derive a class from UpDownBase. An example of this is the NumericUpDown class, which limits the values to the numeric type and uses a Minimum and Maximum property to validate the data.

To allow the user to use the arrow keys to change the contents of a spin box, set the InterceptArrowKeys property to true. To restrict the user to values you specify, set the ReadOnly property to true. To control the alignment of text in the spin box, set the TextAlign property. To set the alignment of the up and down buttons in relation to the text box portion of the control, set the UpDownAlign property to either Left or Right.

The UpButton and DownButton methods, when overridden, handle the clicking of the up or down buttons. When overridden, the ValidateEditText and UpdateEditText methods validate the value (either selected or entered) and update the text displayed in the spin box. If the value fails validation, use the Select method to select the text that is not valid. This allows the user to quickly correct the text by simply typing in a new value without having to manually select or delete the existing text.

Starting with the .NET Framework 4.6, the UpDownBase control will be resized based on the system DPI setting when the app.config file contains the following entry:

<appSettings>  
  <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />  
</appSettings>
