Properties

Name	Property Type	Summary
ButtonsAlignment	ButtonsAlignment	The ButtonsAlignment property specifies horizontal alignment of the up/down buttons.
ChangeValueOnTextChanged	bool	Gets or sets a value indicating whether the value will be changed directly on every TextBox text changed input event or when using the Enter key.
Culture	CultureInfo	Gets or sets a value indicating the culture to be used in string formatting and converting operations.
DecimalPointCorrection	DecimalPointCorrectionMode	Gets or sets the decimal-point correction mode. The default is `Inherits`
Delay	int	Gets or sets the amount of time, in milliseconds, the NumericUpDown waits while the up/down button is pressed before it starts increasing/decreasing the `Value` for the specified `Interval` . The value must be non-negative.
HideUpDownButtons	bool	Gets or sets a value indicating whether the up/down button of the control are visible.
InterceptArrowKeys	bool	Gets or sets a value indicating whether the user can use the arrow keys `Key.Up` and `Key.Down` to change the value.
InterceptManualEnter	bool	Gets or sets a value indicating whether the user can enter text in the control.
InterceptMouseWheel	bool	Gets or sets a value indicating whether the user can use the mouse wheel to change the value.
Interval	double	Gets or sets the interval value for increasing/decreasing the `Value` .
IsReadOnly	bool	Gets or sets a value indicating whether the text can be changed by the use of the up or down buttons only.
Maximum	double	Maximum restricts the maximum value of the Value property.
Minimum	double	Minimum restricts the minimum value of the Value property.
NumericInputMode	NumericInput	Gets or sets which numeric input for this NumericUpDown is allowed.
ParsingNumberStyle	NumberStyles	Gets or sets the parsing number style for the value from text to numeric value.
SnapToMultipleOfInterval	bool	Indicates if the NumericUpDown should round the value to the nearest possible interval when the focus moves to another element.
Speedup	bool	Gets or sets a value indicating whether the value to be added to or subtracted from `Value` remains always `Interval` or if it will increase faster after pressing the up/down button/arrow some time.
StringFormat	string	Gets or sets the formatting for the displaying `Value`
SwitchUpDownButtons	bool	Gets or sets a value indicating whether the up/down buttons will be switched.
TextAlignment	TextAlignment	Gets or sets the horizontal alignment of the contents inside the text box.
