I have been struggling with getting FormViews to work the way Microsoft expects me to for about a day and have figure a bunch of great stuff out. I can catch e.Exception and e.ReturnValue in the ObjectDataSource.Inserting Event Handler and I can even cheat and check other properties of the Object in the ObjectDataSource.ObjectDisposing ...
I have a gridview bound to an objectdatasource which handles paging. This all works great until there is less rows to display than the paging allows. In my case the paging is set to 50 but there are only 30 rows to display. The grid renders correctly but i have (1 2 3 4 ...) pages displayed in the grid. When you select a page it returns ...
I mean I have a gridview in aspx. Then I have the ObjectDataSource. It's binding, it looks all right. Got paging allow = true also. I don't want to go again to the database for the same datatable (ObjectDataSource's Selectmethod), so I'd like to do something like: DataTable dt = ObjectDataSource.GetOriginalDataTableLoadedFrom(); Atr...

I'm considering using an ObjectDataSource as an intermediate between my page controls and my data access layer & object model. Traditionally I have manually created the object and populate it via a series of findcontrol statements when I need to insert/update data in the database. I'm hoping that I can use the ObjectDataSource to marsh...

I have a large brown field webforms app that uses ObjectDatasource controls all over the place, which makes refactoring more difficult than it should be. Is there a way to get a comile-time failures if an object or method is renamed which would cause the ObjectDataSource no longer work? In MVC there is the notion of compiling views, is ...
