NumericUpDown.ThousandsSeparator Property

Definition

Gets or sets a value indicating whether a thousands separator is displayed in the spin box (also known as an up-down control) when appropriate.

public:
 property bool ThousandsSeparator { bool get(); void set(bool value); };
public bool ThousandsSeparator { get; set; }
member this.ThousandsSeparator : bool with get, set
Public Property ThousandsSeparator As Boolean

Property Value

true if a thousands separator is displayed in the spin box when appropriate; otherwise, false. The default value is false.

Examples

The following code example creates and initializes a NumericUpDown control, sets some of its common properties, and allows the user to change some of these properties at run time. This code assumes three CheckBox controls have been placed on a form and handlers for their Click events have been instantiated. The DecimalPlaces, ThousandsSeparator, and Hexadecimal properties are set on the Click event of each check box.

public:
   void InstantiateMyNumericUpDown()
   {
      // Create and initialize a NumericUpDown control.
      numericUpDown1 = gcnew NumericUpDown;
      
      // Dock the control to the top of the form.
      numericUpDown1->Dock = System::Windows::Forms::DockStyle::Top;
      
      // Set the Minimum, Maximum, and initial Value.
      numericUpDown1->Value = 5;
      numericUpDown1->Maximum = 2500;
      numericUpDown1->Minimum = -100;
      
      // Add the NumericUpDown to the Form.
      Controls->Add( numericUpDown1 );
   }

private:
   // Check box to toggle decimal places to be displayed.
   void checkBox1_Click( Object^ sender, EventArgs^ e )
   {
      /* If DecimalPlaces is greater than 0, set them to 0 and round the 
         current Value; otherwise, set DecimalPlaces to 2 and change the 
         Increment to 0.25. */
      if ( numericUpDown1->DecimalPlaces > 0 )
      {
         numericUpDown1->DecimalPlaces = 0;
         numericUpDown1->Value = Decimal::Round( numericUpDown1->Value, 0 );
      }
      else
      {
         numericUpDown1->DecimalPlaces = 2;
         numericUpDown1->Increment = Decimal(0.25);
      }
   }

Remarks

When the ThousandsSeparator property is set, the UpdateEditText method is called to update the spin box's display to the new format.

The appropriate thousands separator is determined by the regional settings of the user's operating system.
