I as delighted to see WebListbox has a DataSource property which works together with the DataSource interface und thought it would be an ideal way to handle longer lists in a Web app without having to implement a paging mechanism to keep the app responsive.
Sadly, I could not figure out how to update the listbox after changes to the datasource.
When I use the IDE example (Web/Controls/ListboxDataSource) and change the code of the buttons Action event handler so that it adds another name, nothing happens. A RefreshCell on the newly added cells results in an OutOfBounds exception, and assigning the Datasource instance to the listbox again after adding a name simply does nothing.
Is the interface not meant for dynamic handling of data? Or did I miss some information?
