根据类型编号获取父类名称
-- =============================================
CREATE FUNCTION [dbo].[FN_getParentTypeNameByTypeID]
(
@TypeID INT
)
RETURNS NVARCHAR(100)
AS
BEGIN
DECLARE @parentTypename NVARCHAR(100)
SELECT @parentTypename=TypeName FROM BioProType
WHERE TypeID=(SELECT ParentTypeID FROM dbo.BioProType WHERE
[email protected])
RETURN @parentTypename
END
1.管理页面实现产品类型列表显示（分页）。
前端的代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ProTypeListShow.aspx.cs" Inherits="BioErpWeb.WholeSaleSystem.Product.ProTypeListShow" %> <%@ Register assembly="AspNetPager" namespace="Wuqi.Webdiyer" tagprefix="webdiyer" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="../../Styles/ERPBaseStyle.css" rel="stylesheet" type="text/css" /> <link href="../../Styles/AspNetPagerStyle.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script src="../../Scripts/jquery.validate.js" type="text/javascript"></script> <script src="../../Scripts/ValidateMessage_ZW.js" type="text/javascript"></script> <script src="../../Scripts/validateExtender.js" type="text/javascript"></script> <script src="../../Scripts/jquery.metadata.js" type="text/javascript"></script> <script src="../../JS/ProTypeChoose.js" type="text/javascript"></script> <script type="text/javascript"> $().ready(function () { $("#form1").validate();

删除节点的通用方法：
/// <summary>
/// 删除指定表 父级节点下面的所有子节点。
/// </summary>
/// <param name="tableName">表名</param>
/// <param name="ParentNodeID">编号</param>
public static void deleteParentNode(string NodeID)
{
//DataTable dt = "select id from table where upid=" + id;
DataTable dt = SqlComm.GetDataByCondition("BioProType", "TypeID", " ParentTypeID=" + NodeID).Tables[0];
//存在子级的
if(dt.Rows.Count>0)
{
foreach (DataRow aRow in dt.Rows)
{
//递归搜索子级
deleteParentNode(aRow["TypeID"].ToString());
}
//删除子节点后再删除当前节点。
SqlComm.DeleteTableByCondition("BioProType", " where TypeID=" + NodeID);
}
//删除不存在的
else
{
SqlComm.DeleteTableByCondition("BioProType", " where TypeID=" + NodeID);
}
}
后台代码：
public static int pageindex = 0;
public static int pagesize = 10;
public static string condition = "";
protected void Page_Load(object sender, EventArgs e)
{
////Session["Userid"] = "29";
if (!IsPostBack)
{
getallPageList();
}
}
/// <summary>
/// 查询所有联系人信息
/// </summary>
private void getallPageList()
{
this.AspNetPager1.RecordCount = SqlComm.getDataCountByCondition("dbo.BioProType", condition);
this.AspNetPager1.PageSize = pagesize;
this.GridView1.DataSource = SqlComm.getDataByPageIndex("dbo.BioProType", "*,parentTypeName=dbo.FN_getParentTypeNameByTypeID(TypeID)", "TypeID", condition, pageindex, pagesize);
this.GridView1.DataBind();
}
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
pageindex = this.AspNetPager1.CurrentPageIndex - 1;
getallPageList();
}
protected void imgbutnSearch_Click(object sender, ImageClickEventArgs e)
{
pageindex = 0;
condition = "";
if (txtName.Text.Trim() != null && this.txtName.Text.Trim().Length != 0)
{
condition = condition + " and TypeName like ‘" + txtName.Text + "%‘";
}
getallPageList();
}
protected void imgbtnNew_Click(object sender, ImageClickEventArgs e)
{
Response.Redirect("ProTypeInsert.aspx");
}
BioProType type = null;
static string id = "";
protected void btnSubmit_Click(object sender, EventArgs e)
{
//if (type == null)
//{

//}
BioProType type = new BioProType();
type.TypeID = int.Parse(id);
type.TypeName =this.txtTypeName.Text;
type.ParentTypeID =int.Parse(this.txtSupertTypeID.Text);
BioProTypeBLL typebll = new BioProTypeBLL();
if (typebll.ProTypeUpdate(type) != 0)
{
getallPageList();
}
else
{

}
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{

if (e.CommandName == "ImgEdit")

}

getallPageList();
}
