This step of the VIDEO TUTORIAL will show case on how to alert one of the concurrent users about concurrency exceptions. This is achieved by adding two message labels on the OptimisticConcurrency.aspx web page, one for Update concurrency exception and the other for the exception resulting from Delete process. The exception resulting from the Update process is handled in the GridView control’s RowUpdated event handler, whereas, the concurrency exception resulting from the Delete process is handled by the ObjectDataSource control’s Deleted event handler. For detailed information and source code for this step, please refer to the original article.
