Vb.net 禁用BindingNavigator中的PositionItem

我使用禁用了PositionItem框

BindingNavigatorPositionItem.Enabled = False

但每次单击下一行时，它都会再次启用

我甚至试图通过添加

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

如果启用或未启用，如何进行控制？

Ref:

BindingNavigator按钮的单击事件是默认的封装行为，用于基于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

您可以覆盖事件的功能，如下所示：

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

好好尝试。我为你工作真是太好了。。我将把这个作为回答。。
