I want to use NumericTextBox to input student scores. Most of the time this is numbers. It's easier with tablets.

However we have some special codes that we have to treat.

Like "AB" for Absent, ou "EX", Exemption.  We convert these code to negative numbers, on input/output.

What do you think is the better way to deal with this kind of input with Kendo ? 

Thanks

Hello Andre,

The NumericTextBox has been designed to accept and handle numeric input only. If using some custom logic (such as negative numbers) is considered inappropriate, I advise you to use a separate field for the AB / EX designations.

All the best,
