Hello,

 

I have a table that is bound to a model that is json from the backend. Users can change the data in the table and add rows to it and then there is a save button that sends the new data back to the abap backend.

 

Is there a way if the user navigates from the table that they can get an alert informing them that if they continue they will lose all their data they added/changed in the table, unless they hit the save button. Is there something for this? Thanks!
