[EDIT: Turns out I can change properties, but just the ones that were serialized, and not the relationships!The entities build in Linq Data Source are disconnected entities you'll have to attach them to the datacontext to do get access to the foriegn key relationship properties. Now here's another question: when I've reattached the entity, modified all the relationships I want, how do I save it to the DB? ]Alternatively when I save the new entity manually to the DB, I have to cancel the update via e.Now I did not find anyway to write VB code to trap onkeypress event. But in javascript, I was not able to access my exitsting data object like connection and dataset. The table that I want to update consists of two foreign key fields. I have 3 tables: TABLE1(col1, col2, other columns...) TABLE2(col1, col2, other columns...) TABLE3(col1, col2, other columns...) (col1 col2) is the primary key for TABLE1. I would need to execute somenthing like: BEGIN TRANSACTION; UPDATE TABLE1 SET col1 = :newvalue WHERE col1 = :oldvalue; UPDATE TABLE2 SET col1 = :newvalue WHERE col1 = :oldvalue; UPDATE TABLE3 SET col1 = :newvalue WHERE col1 = :oldvalue; COMMIT TRANSACTION; Thank yo...

As in my case I need to query only from current database session as my transaction is not over yet. How would I go about retrieving the foreign key fields?

TABLE2 and TABLE3 have foreign keys to (col1 col2). Invoking the Updated/Updating events without a XXData Source object Is there a way to have a data control (ie. NET data provider, which returns data in a table format to integrate seamlessly with relational products, Matisse has extended the ADO.

In the event routine you loop through each FK-column of the current table and invoke the update proc.

This is necessary since I found no way to get the current column from the Event Args.

works like a charm and has the right insert-order : D Since I received a PM asking me how I solved it, I might as well post it here for future reference...

The basic idea is to handle the Updating and Inserting events of the datasource and the go from there.

Dunk ---== Posted via the PFCGuide Web Newsreader ==--- you want to update a key which is used as a FK on another table the best bet is to cascade changes (if that's an option on your database).
