Hi Zzdfc, you could do domething like this:

protected void GridDataSource_Deleting(object sender, EntityDataSourceChangingEventArgs e)
{
    var entity = e.Entity as Employee;
    var DC = new Models.NorthwindDataContext();

    var log = new Log()
    {
         EntityID = entity.EmployeeID,
         TimeDeleted = DateTime.Now,
         DeletedBy = User.Id
    };
}

However if you wanted to just mark the employee as deleted instead of deleting them then you could USE SPROCS to replace default L2S or EF actions see:

Hi Zzdfc, your best bet is to handle the EntityDataSource's OnDeleting event e.g:

protected void GridDataSource_Deleting(object sender, EntityDataSourceChangingEventArgs e)
{
    var entity = e.Entity;
}

You can get the actual entity from e.Entity and then do what ever you want before letting the EDS finish the delete.

What are you using Entity Framework or Linq to SQL?

You can handle the events on the Deleting/Deleted events on the datasource.
