我通过使用禁用了 PositionItem 框

BindingNavigatorPositionItem.Enabled = False

但是每次我单击下一行时，它都会再次启用。

我什至试图通过添加来强制禁用它

 Private Sub BindingNavigatorMoveNextItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorMoveNextItem.Click
    BindingNavigatorPositionItem.Enabled = False
 End Sub

我如何控制它是否启用？

参考：MSDN - 禁用绑定导航器

BindingNavigator 按钮的 Click 事件已被默认封装为基于 BindingNavigatorPosition 设置其他按钮的 Enable 属性，因此您可以设置Me.BindingNavigator1.PositionItem.Available = False或BindingNavigatorPositionItem.Visible = False。

您可以将事件的功能覆盖为：

Private Sub BindingNavigatorAddNewItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles BindingNavigatorAddNewItem.Click  
  BindingNavigator1.BeginInvoke(New MethodInvoker(AddressOf DisableItems))  
End Sub 

Private Sub DisableItems()  
  BindingNavigatorMoveFirstItem.Enabled = False 
  BindingNavigatorDeleteItem.Enabled = False 
  BindingNavigatorAddNewItem.Enabled = False 
  BindingNavigatorMoveLastItem.Enabled = False 
  BindingNavigatorMoveNextItem.Enabled = False 
  BindingNavigatorMovePreviousItem.Enabled = False 
  BindingNavigatorPositionItem.Enabled = False 
End Sub`

您可以将BindingNavigatorPositionItem.Enabled = False语句放在BindingNavigatorPositionItem的CotFocus 事件处理程序中， 如下所示：

Private Sub BindingNavigatorPositionItem_GotFocus(ByVal sender As Object,
                                                  ByVal e As System.EventArgs) Handles BindingNavigatorPositionItem.GotFocus
    BindingNavigatorPositionItem.Enabled = False
End Sub
