Input Restrictions
The NumericTextBox enables you to control the precision of the entered number and also restrict its value to a specific range.
Numbers
The NumericTextBox controls the precision of the entered number by using the value of the decimals option which limits the length of the input number to the decimals length.
By default, the widget does not restrict the length of the typed value. To enforce a specific fraction length during editing, set the restrictDecimals option to true.
The widget controls the precision of the entered number by using the half-up rounding technique. To disable this functionality, use the round configuration option. Once you turn off the rounding, the value is truncated up to the desired precision length without rounding it.
For a complete example, refer to the demo on restricting decimals and rounding numbers in the NumericTextBox.
Value Ranges
You can restrict the value of the NumericTextBox to a specific range by using either of the following approaches:
- Restrict the input value between a specific
minandmaxrange. The typed value gets modified to fit the range onblur. - Use a custom Kendo UI Validator rule to restrict the input value. The invalid value remains unchanged and the user is notified for the incorrect input by an error message. For more information, refer to the article on the custom validation rules. For a complete example, refer to the demo on range validation in the NumericTextBox.
