I now saw the update. Is there a good reason not to bind to the Header table instead of the Status table? Bind to the Header table and then bind the selected value as you are currently. Then there is no need to update the combo box if the record contains a status item not in the Status table.

Just to be clear: You want the combobox to include status items from a status table AND the status item from the corresponding record (only if the record contains a status item not in the status table). Seems like this shouldn't happen. The status column of the record should be associated with the status table. Then, if there needs to be another status, the table will be updated and along with it (since it is data-bound) the combobox will be updated. If this is not the case:

The record's status item will need to be added to the combo box after the combo box contains its items from the status table. So, once the combo box is updated with the items from the status table, add the extra item from the record. You can do this in various ways. Some logic must be in place before adding the extra item to the combobox: make sure the record's status item is not already in the combobox (or in the status table).

I suggest passing a variable to the function like: function (e) { ...event code... } then you can add this: e = e || window.event; It almost guarantees a workable event object. That said, this only works with browsers other than IE: examine the event object to obtain "event.srcElement.activeElement". there you can get the element type such as a link (which would indicate it is a page). Knowing this, you will then be able to cancel the onbeforeunload event.
