We have a requirement to display a warning to the user,

- If the user has done some changes in the existing Portal screen (Like adding a row to a table/Editing values in a row) - And tries to Switch to any other Portal screen, by Clicking on left navigator (Basically should work very similar to Dirty Warning Display)

Note : We're using Case Manager Portal for our application.

Is there a way to achieve this. Would appreciate some assistance on this. Thanks.
