Validating multiple fields in flex

06 Sep

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

The individual pieces of data in a record are called fields.

You cannot change a field's type without data loss.

For custom fields, the system prompts you to confirm you accept the data loss before proceeding with the change.

I call it on key Up on every field that is required and check for values in all of the fields (and any other validation I want to do) and then as long as everything checks out I set the submit button to be enabled otherwise I set the submit button to be disabled.

In the next exercise you will populate a Column Chart control bound to value object instances stored in the employees Array Collection instance.I will look at the docs and see if I can see what you can do with the required attribute on the form item though.I obviously wanted to use one validator for all of the email addresses since they all need to be validated the same way.As long as you disable the button when you start then you should be good to go.I have used this method several times and find it to be the easiest to use and especially to maintain.You can implement the Name Validator class, as the following example shows: In this example, because you are using a single validator to validate three subfields of the Object passed to the validator, you include the optional second argument to the constructor for the Validation Result class to specify the subfield that caused the validation error.This inclusion permits Flex to identify the input component that caused the error, and to highlight that component in the application.I couldn’t find any great examples on the internet so I am posting the code to validate multiple fields with one validator.A validator can validate more than one field at a time.
