binding controls to objects

[Moorzee]

Question: I have a form with a tabstrip and controls on the pages bound to my class as a datasource. I default my combos and other controls on loading the form. If I am adding a new record(my objects values are empty strings, 0 etc..),as I select a page on the tab strip the controls are being reset to reflect the objects state(empty, 0, null whatever)

I've changed the datasource update mode of the control to be "onpropertychanged" and this seems to be ok but I am wondering if anybody knows any reason why this would not be he default method as it seems correct in my mind?

Cheers.

BTTT.
Doe's anyone have any thoughts on the datasourceupdate property and if I could be creating a massive ballache for myself by selecting the non-default method?

Cheers
