Decimal Places

DecimalPlaces property specifies number of values allowed after the decimal point.The default value of DecimalPlaces property is 0 i.e., by default you cannot specify decimal value in NumericTextBox. We need to add this property to allow decimal values. To set the DecimalPlaces to “-1”, that allows the decimals without any limit in NumericTextBox control.

Configure Decimal Places

CSHTML

@Html.EJ().NumericTextbox("numeric").DecimalPlaces(3).Value("333")

Strict Mode Support

NumericTextBox allows you to use the strict mode option by setting the EnableStrictMode property. You can set the MinValue and MaxValue to the controls to enable strict mode functionality. Default value of this property is false. When the textbox value exceeds the MaxValue, it restricts the exceeded value and returns the MaxValue. Likewise when the textbox value goes below MinValue, it restricts the new value and returns the MinValue. When this property is enabled, it will not restrict the specified value and an error class is added to indicate wrong value is provided to the textbox.
