How to: Set the Format for the Windows Forms NumericUpDown Control

  • Article

You can configure how values are displayed in the Windows Forms NumericUpDown control. The DecimalPlaces property determines how many numbers appear after the decimal point; the default is 0. The ThousandsSeparator property determines whether a separator will be inserted between every three decimal digits; the default is false. The control can display values in hexadecimal instead of decimal format, if the Hexadecimal property is set to true; the default is false.

To format the numeric value

  • Display a decimal value by setting the DecimalPlaces property to an integer and setting the ThousandsSeparator property to true or false.

    NumericUpDown1.DecimalPlaces = 2  
NumericUpDown1.ThousandsSeparator = True  

    numericUpDown1.DecimalPlaces = 2;  
numericUpDown1.ThousandsSeparator = true;  

    numericUpDown1->DecimalPlaces = 2;  
numericUpDown1->ThousandsSeparator = true;

    -or-

  • Display a hexadecimal value by setting the Hexadecimal property to true.

    NumericUpDown1.Hexadecimal = True  

    numericUpDown1.Hexadecimal = true;  

    numericUpDown1->Hexadecimal = true;

    Note

    Even if the value is displayed on the form as hexadecimal, any tests you perform on the Value property will be testing its decimal value.
