      Hi all,

          Hi jfb00,


          The Flex inbuilt validators can be used for specific form fields. But in case you want to apply them dynamically and reduce much work of adding them for each field, I would suggest this.


          Have a utilty class which has methods to handle your number validator/string validator etc.


          Have a Custom Form field or a a Custom TextInput class.


          In your custom textinput class i.e; extends the mx.controls.TextInput, you must have any variables which helps you to customize your validations if required. Like , you can have some properties like "type" and declare it as inspectable property. This means, you can specify the text input type in your mxml. Check for these properties value on focusout or change event of your custom textinput and handle them by calling the appropriate validator methods from your utility class.  The value returned from your method in the utility class can be taken in your textinput and handle accordingly.(like setting errorString etc).



          If not clear, let me know. I will try posting a sample coe for this. It could take some time for me to make the sample work for you.

            Thanks for your reply and help.

            I got the idea, I will try this but if you have an example that will be better.
