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

17 Feb 20221 minute 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.
