• Windows Forms Any recommendations on troubleshooting a concurrency error?

  I'm trying to run an tableadapter.update after I've deleted a record (using the binding sources removecurrent) and it gives me a concurrency error under seemingly random circumstances. Here is the message I get: Concurrency violation: the DeleteCommand affected 0 of the expected 1 records. Since I haven't been able to determine the source of the error (sometimes it works and sometimes it doesn't), are there any places that anyone can recommend me looking for the problem Thanks for any insight! A concurrency violation will occur whenever a command affects zero records - it doesn't necessarily mean a ...Show All

• .NET Development ConfigurationElementCollection class with properties problem

  I'm creating a ConfigurationElementCollection-derived class for my configuration section. In addition to acting as a container for other elements, I also want the collection to have configuration properties of its own. I defined properties on the collection annotated with [ConfigurationProperty] as usual for a configuration element. Unfortunately, I can't quite seem to get this to work as I would expect. Specifically, the collection properties aren't serialized to the config file, although the elements contained in the collection are serialized correctly. I've found at least one BCL element collection class that tries to do this, so it se ...Show All
