two questions

first, how does the bindingnavigator know that there are no records, and the buttons on it are all disabled

second, i read in a lot of places that the save button is automatically part of the bindingnavigator, but when i drag the component on to my form, i
don't see the save button



thank you

In this case, the BindingSource associated with the BindingNavigator returns Nothing for Current and zero for Count.

No. However, if you use a ToolStrip, it has a command to automatically add standard tool bar buttons. This basically just adds images, you still must provide all the functionality yourself.

You might find that the BindingNavigator is underpowered / hard to customize. In this case, you can create a ToolStrip with exactly the buttons you want and call the relevant methods on the BindingSource when the user presses buttons(such as MoveNext, etc.).
