Having created a database and testing it I get the following error message,

ARGUMENT EXCEPTION WAS UNHANDLED

Public Class Form1

Private Sub AddressBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddressBindingNavigatorSaveItem.Click
Me.Validate()
Me.AddressBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.ThePhoneBookDataSet)

End Sub

The line

Me.AddressBindingSource.EndEdit()

being highlighted.


My action during the test was to fill in a field, save it then changed the information within, only to get the above message.

Whats gone wrong
