的解决方案是简单的（从数据库中删除之后）。删除后，再次加载组合框中的数据..

Private Sub btn_remove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_remove.Click 
    Dim Query As String 
    mysqlconn.Open() 
    Query = "delete from table where screen_id='" & cmb_id.Text & "' " 
    Dim cmd As MySqlCommand = New MySqlCommand(Query, mysqlconn) 
    Dim i As Integer = cmd.ExecuteNonQuery() 
    If (i > 0) Then 
     MsgBox("Record is Successfully deleted") 
**===> load the data here or call the function that load the data in the combo box** 
    Else 
     MsgBox("Record is not deleted") 
    End If 
    mysqlconn.Close() 
End Sub
