Asp objectdatasource onupdating Chatroulette cam pics
Thanks Andrew Hello Andrew, For your scenario, your data access class's update method will take a int input parameter and you use it in Object Datasoruce, and the parameter source is a List Box(configuer as multi-select ), I think you need to take care of the following things: 1. Items to Object Data Source's update parameter, because they're unmatched on type(one is List Item Collection, the other is int) 2. Page ============================== Actually, for such scenario, it's more straightforward that we directly call the custom class's method instead of Object Data Source.

The object that contains the original data is passed as a parameter to the Update method.
The target audience for this series are developers that are ready to make the switch from using controls with custom business objects. NET 2 and C# is necessary while some knowledge about object oriented design certainly helps.
This is part three of the article series "Building Layered Web Applications" that shows you how to build N-Layer applications with Microsoft ASP. These articles teach you how to design, build and use custom business objects in your web application.
I was able to get everything to work correctly with the Grid View except when it came to performing an update.
This effectively removes the additional parameters from being added.
