    <p>As we use LINQ2SQL this task is quite easy to be acoomplished overriding the SubmitChanges() method. Our main goal is to do auditing in our tables. The code would like this:</p> <pre><code> /// &lt;summary&gt; /// Sends changes that were made to retrieved objects to the underlying database, /// and specifies the action to be taken if the submission fails. /// NOTE: Handling this event to easily perform Audit tasks whenever a table gets updated. /// &lt;/summary&gt; /// &lt;param name="failureMode"&gt;The action to be taken if the submission fails. /// Valid arguments are as follows:&lt;see cref="F:System.Data.Linq.ConflictMode.FailOnFirstConflict"/&gt; /// &lt;see cref="F:System.Data.Linq.ConflictMode.ContinueOnConflict"/&gt;&lt;/param&gt; public override void SubmitChanges(System.Data.Linq.ConflictMode failureMode) { //Updates for (int changeCounter = 0; changeCounter &lt; this.GetChangeSet().Updates.Count; changeCounter++) { object modifiedEntity = this.GetChangeSet().Updates[changeCounter]; SetAuditStamp(this, modifiedEntity, ChangeType.Update); } //Inserts for (int changeCounter = 0; changeCounter &lt; this.GetChangeSet().Inserts.Count; changeCounter++) { object modifiedEntity = this.GetChangeSet().Inserts[changeCounter]; SetAuditStamp(this, modifiedEntity, ChangeType.Insert); } base.SubmitChanges(failureMode); </code></pre> <p>We particulary don't like using triggers as they are always hidden into you DB and it makes hard to work out problems that may occur ... with having that into your code you just need to start debugging it to find out why something has failed for instance ...</p>

    1. COagreed that triggers stink for the reason mentioned. TOTALLY disagree that auditing is best done outside the database. If you have EXTREMELY tight enforcement of access requests, such that there's no possible way that anyone could get a username/pw to your DB then you MIGHT have a fighting chance.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
