Hi Maurizio,

hmm, might be a version change issue. The 3.5 docs say little about it, from 2.4 docs I see:

Using Business Object Hook Methods
...
HookPreSave
Hook method in which developers can place code to be executed before a data table is saved. If this method returns false, the save is aborted.


protected virtual bool HookPreSave(DataTable dt)
Protected Overridable Function HookPreSave(dt As DataTable) As Boolean

I use it to update lastuser and lastupdate fields when updating the table behind the object.
