The IlvNumberField
class is a subclass of IlvTextField
defining a specialized text field that accommodates numeric values with various formats. It lets you specify the minimum and maximum values allowed in the number field. The validate callback is invoked only if the field contains a numeric value and this number is between the specified limits.
