I am in the process of designing a generic 'record maintenance' toolbar class containing the 'standard' add/edit/delete/save/cancel buttons. I notice that the VS toolbox already has a bindingnavigator control which already has some of the functionality that I require (although I don't require the navigation buttons).

Which control should I go for? As far as I can see the bindingnavigator is just a glorified toolbar bound directly to a datasource, but I may be missing something.

Can I subclass a toolbar/bindingnavigator visually or does it have to be done in code? I am using C# with VS2005 express.

You can just use Windows Forms' BindingSource and create a decent ToolStrip (previously known as ToolBar in .NET 1.x), with your own buttons with custom actions.

The problem with the BindingSource is that I don't require the navigation buttons, which only leaves the add and delete buttons, so I would have to add my own edit/save/cancel buttons. It might make more sense for me to create my own customised toolstrip.

Using VS 2005 IDE, you can just add BindingSource by dropping from toolbox, and then start to create your own ToolStrip with your own data manipulation buttons. Dropping BindingSource doesn't create new BindingNavigator on your Form.
