After some debugging, I found that, BO.ParentBusinessObject is already become null in Field_FieldName_Descriptor.SetValue(). Once I leave this method, the ParentBusinessObject "came back".<br> <br> Any ideas? Anyone able to access ParentBusinessObject in FieldPropertyChanged without problem?<br> <br> Thank youMon, 21 Jan 2008 10:00:39 GMTChanhttp://forum.strataframe.net/FindPost13594.aspxFor business objects to work properly with a grid, we had to create the BusinessBindingSource, which creates a new instance of the business object for each record that is accessed through the BusinessBindingSource... these business objects all share a common DataTable internally (so they all look like they're the same business object).&nbsp; Most likely, when you see a reference to ParentBusinessObject that is empty, the business object you are referencing is one that has been created by the BusinessBindingSource.&nbsp; So, I think we simply need to set the ParentBusinessObject property on each business object that is created by the BusinessBindingSource... and I don't think it's doing that right now.Mon, 21 Jan 2008 10:00:39 GMTStrataFrame Teamhttp://forum.strataframe.net/FindPost13591.aspxYes.Mon, 21 Jan 2008 09:08:52 GMTChanhttp://forum.strataframe.net/FindPost13588.aspxAre you using the business object within a grid with the BusinessBindingSource?Mon, 21 Jan 2008 08:53:02 GMTStrataFrame Team
