Validating Input Values in Text field

[iparrot]

Hello all, i am trying to implement a TextField where users will have to input values in a certain format with numbers and alphabets, examples are like "NE40.0" or "35SW", "45NW24" etc. How can i validate that the user has put in the correct format. I know its possible to use an ItemStateListener but i am stuck with which comparing method to use or how to compare the strings.

Please any other ideas?

Thank you.

Hi iparrot ,
The simpler way is when ever the user submits the form before that take the input field value and check the and alert the user if it is wrong format.

if you know what must be entered, what about using a choice group (combo box)?
