Vb net updating dataset from datagridview

I would like to give users the ability to update from the datagridview and have the program immediately update the sql server table. Now I am wondering which events to use to validate and update the database, wheter to enable/disable the validating events? The problem is that I'm trying to edit, validate and update behind the scenes by allowing the user to make changes directly to the grid.

My questions related to this are: On which events should I be editing the changed data? How will I need to keep track when user has changed a key column and an update would no longer work? I usually code the data adpater, dataset, and connection string rather than from the toolbox and using an xsd and I usually do not update directly to the datagridview.

when user presses a button (actually file--save) the Installation object is serialized and saved to disk. Goran Ah, I have now seen that you are saying about clickinig on menu. When clicking on the normal button, datagridview looses focus, while clicking on a menu, it doesnt.

It is before the serialization that I do m Installations.productiond I cannot manifest this behaviour. To solve your problem, you need to do two things: 1) Call End Edit on datagridview 2) Call End Edit on Binding Source (or End Current Edit on Currency Manager) Goran I see what you mean with loosing focus.
