改为自己的表名和列名。花时间理解一下代码，不要就会抄

改为自己的表名和列名呀！确定execl里第一列是编号列吗

Dim bh As String = sheet(n,0).Text
If DataTables("订单").Find("编号= \'"& bh &"\'")Is Nothing Then

是不是关我DataColChanging的If e.DataCol.Name = "单号" Then
Dim dr As DataRow
dr = e.DataTable.Find("单号 = \'" & e.NewValue & "\'")
If dr IsNot Nothing Then
MessageBox.Show("此单号已经存在!")
e.Cancel = True
End If
End If 事
