I have a list of items and a corresponding form to edit values based on what the user has selected.
If the user selects another by clicking the grid, I want to provide an Alert popup if they have not saved their changes. If the user clicks OK, then the selection takes place as normal, but if they click cancel, I want to cancel the change event and have the editor stay on the selected item. I can get the event to cancel by declaring an event handler for MouseDown in the creationComplete event, and then having the following lines in the MouseDown handler: event.stopImmediatePropagation(); event.stopPropagation(); event.preventDefault(); The problem is that I can only successfully cancel the event propogation from within this method. If I want to have an alert box with an OK and Cancel button, how do I achieve this? I have tried calling an Alert handler and using a class event variable to store the event that is received by the MouseDown handler, but if I try to cancel the event from within the Alert handler, nothing happens - I think it is too late at that point. Can someone provide me with an example of how to cancel event propogation on a grid click or other similar event based on the user's selection from an Alert prompt? Thanks!
