The viewer is also introduced to customizing ObjectDataSource control properties such as OldValuesParameterFormatString and ConflictDetection.For detailed information and source code for this step, please refer to the original article.

This step of the VIDEO TUTORIAL will continue the customization of GridView controls with various fields that are being displayed in it at run time. This video will also explore further on demonstrating the validation controls at work as well as various exceptions that will be raised during the data entry at run time of the web page OptimisticConcurrency.aspx. This step will also elaborate on alternative strategies such as including dummy labels for ProductID during the implementation of Delete process to avoid exceptions.For detailed information and source code for this step, please refer to the original article.

This step of the VIDEO TUTORIAL will demonstrate the Update and Delete interfaces of the GridView control at run time on the OptimisticConcurrency.aspx web page. This is accomplished by creating two browser sessions of the web page and making an attempt to either edit or delete a particular record by simulating two concurrent users working on the same record.For detailed information and source code for this step, please refer to the original article.
