So I'm following the examples I've seen which allow me to persist the state of my grid between sessions. i.e. if the user adds a filter, adds or removes a column from being visible, etc... What I'd like to do is give the user a visual cue to let them know they are looking at an "altered" grid. I.e. if they apply a filter to the grid, leave the application, come back at a later date and don't realize the filter is still active or they are missing a column, or whatever, I would like to put a thin red border around the div containing the grid. The problem is, I don't see a simple way to see if the grid is in "normal" (as the developer created it) or "altered" (the user has made front end modifications). Is there something I could check to determine this?
