委托编号大排行（自动生成）:

效果：

描述：在本表中自动生成编号，自动生成的编号为所有表中的排序。例如：在添加页面中生成的委托编号未00048，那么在别的表中生成的编号为00049。

调用：

 1 protected void Page_Load(object sender, EventArgs e)
 2         {
 3             Response.Expires = -1;
 4             if (!IsPostBack)
 5             {
 6              
 7                 if (ActionType == CommonEnum.ActionLevel.Write)
 8                 {
 9                     
10                     tbwtbh.Text = Getwtbh();
11                     
12                 }
13             }
14         }
15 
16 protected string Getwtbh()
17         {
18             string Getwtbh = CommonFunction.GetByMenuCode(ThisPositionID, ApplicationInfo.SerialNumWt, "qjlzhuan_lydj", "wtbh");
19             return Getwtbh;
20         }
