Master/Detail Filtering With Two DropDownLists:
Step 3-Using a DetailsView to Display Details for the Selected Product

This step of the VIDEO TUTORIAL will outline on how to display the detail product information in a DetailsView data web control. The DetailsView control will be bound to an ObjectDataSource control that invokes the GetProducstbyProductID method of the ProductsBLL logic layer. This method takes the ProductID as a parameter which will be obtained from the selected product category of second dropdownlist on the webpage. Once a selection is made in the second dropdown list, a post back occurs and the relevant product information will be displayed in the DetailsView data web control on the web page after invoking the ObjectDataSource’s selecting event handler. Finally, an introduction on the sequence of events that happen during the life cycle of the DetailsView’s ObjectDataSource control will be demonstrated.
