Restrict to type decimal points in a NumericTextBox while editing the numeric column in Angular Grid component

30 Jul 2021 / 2 minutes to read

By default, the number of decimal places will be restricted to two in the NumericTextBox while editing the numeric column. We can restrict to type the decimal points in a NumericTextBox by using the validateDecimalOnType and decimals properties of NumericTextBox.

In the below demo, while editing the row we have restricted to type the decimal point value in the NumericTextBox of Freight column.
