Hi Jefferey Mitchell,
Greetings from Syncfusion support.
The Syncfusion EJ2 NumericTextBox does not support group
separators, such as commas or spaces. It is designed to accept numeric values
that adhere to a specific format, including numbers, an optional sign (leading
or trailing), and a single decimal point.
To utilize the NumericTextBox effectively, kindly paste the
value without commas or any other non-numeric characters. For instance, you can
successfully paste a value like '-11' or '3.14' but it won't accept values with
spaces or commas, such as '1 000' or '1,234.56.'
Note: When you paste valid input, a thousand
separators are automatically created, and the commas appear once you focus out
of the component.
Regards,
