Values input in an input field of type text or combo can be subjected to a validation. Depending on the type of content, different validators or a combination of validators is used.
- numberRangeValidator: The permitted range of values for a number is defined by means of an upper limit and a lower limit.
- contentValidator: Input text is checked with the help of a regular expression.
- keyValidator: The input is restricted to a specific subset of characters with a regular expression.
If the validators are combined, the following sequence has to be followed:
- keyValidator
- contentValidator
- numberRangeValidator
