# NumericUpDown

A Wisej.NET `NumericUpDown` control contains a single numeric value that can be incremented or decremented using the up or down buttons. Users can enter values directly unless the `ReadOnly` property is set to `true`.

Format the numeric display using the `DecimalPlaces`, `Hexadecimal`, or `ThousandsSeparator` properties. Set `Hexadecimal` to `true` to display hexadecimal values. Enable `ThousandsSeparator` to display the thousands separator in decimal numbers. Set `DecimalPlaces` to specify the number of digits after the decimal symbol.

## Features

### Label

The `NumericUpDown` control supports the inline [Label](/docs/controls/general/labels.md) property. This allows setting a label in relation to a `NumericUpDown` control without creating an additional `Label` control.

### Formatting

The `NumericUpDown` control offers several formatting properties. The `Prefix` property prepends a character or string to the value. The `Postfix` property appends a character or string to the value. Enable the `ThousandsSeparator` property to display commas for values exceeding three digits.
