C# DataTable 递归

DataTable 递归简单的程序，来实现无限级列表结合 jquery.table.js 实现

protected void DiGuiDataTable(DataTable FromDataTable, DataTable ToDataTable, object pid) { ) { foreach (DataRow item in FromDataTable.Select("pid='" + pid + "'")) { ToDataTable.Rows.Add(item.ItemArray); DiGuiDataTable(FromDataTable, T

ASP.NET通过递归添加树(Treeview)

先来看看效果,基本上就是这样的. 所谓树,无非就是2点,第一个:根节点,第二:叶子节点,其中叶子节点中还可能有叶子节点,但是根节点始终只有一个. 下面贴上各部分的代码 1.PAGE_LOAD载入事件. protected void Page_Load(object sender, EventArgs e) { BindTree(); //绑定树 } 2.BindTree方法. private void BindTree() { DataSet ds = new DataSet(); //这里的

for循环递归树

protected string _menu = string.Empty; public void FirstAnsyData() { try { // List<object> lsNode = new List<object>(); string strsql = "select * from S_module"; DataSet dt = DbHelperSQL.Query(strsql); // lsNode = getList(tab); ////

将DataTable生成树json

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { ListMenu(); } } protected string _menu = string.Empty; public void ListMenu() { StringBuilder sb = new StringBuilder(); DataTable _list = new DataTable(); string ConctionStr =

EasyUI TreeGrid DataTable转换数据实现案例

C#部分 /// <summary> /// Handler1 的摘要说明 /// </summary> public class Handler1 : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; int OneID = int.Parse(context.Request["ID

net TreeView 递归

1.显示效果 2.数据insert脚本 insert into CITY(id,text,pid) values('1','城市',null)insert into CITY(id,text,pid) values('2','北京市','1')insert into CITY(id,text,pid) values('3','上海市','1')insert into CITY(id,text,pid) values('4','天津市','1')insert into CITY(id,text,

DevExpress中的ASPxTreeView 递归显示checknodes并获得选中值

aspx代码 <dx:ASPxTreeView ID="ASPxTreeView1" runat="server"> </dx:ASPxTreeView> aspx.cs代码 protected void Page_Load(object sender, EventArgs e) { AddTree(, null); } private void AddTree(int Pid, TreeViewNode PNode) { SQLHelper

《转》---使用递归方法DataTable 绑定 TreeView

转自:http://blog.sina.com.cn/s/blog_8944756d01016yaj.html 前台: <asp:View ID="view0" runat="server"> <asp:TreeView ID="treeLanMu" runat="server" ImageSet="Arrows" ons

C# 最原始的tree 递归使用

; i < dr.Rows.Count; i++) { ) { n.id = Convert.ToInt32(dr.Rows[i][; i < dr.Rows.Count; i++) { tree n = ; BindNew(model);]; return

TreeView递归绑定数据的两种方法

#region 绑定TreeView /// <summary> /// 绑定TreeView(利用TreeNode) /// </summary> /// <param name="p_Node">TreeNode(TreeView的一个节点)</param> /// <param name="pid_val">父id的值</param> /// <param name="id

ASP.NET递归添加树节点

表设计如图: id title parentid 1 asp.net 0 2 c# 0 3 c#_0 2 4 c#_1 3 5 c#_2 4 页面中添加一个TreeView控件写添加节点方法: private void AddNode(int id, TreeNode parentnode) { string sql = "s

C#递归树

protected void Page_Load(object sender, EventArgs e) { bindtree(PopId); } private void bindtree() { TreeView1.Nodes.Clear(); AddTree(, (TreeNode)null); } public void AddTree(int ParentID, TreeNode pNode) { DataTable dt = new DataTable(); //数据源 dt = l

treeview树形菜单，递归

我使用的是递归是实现无限级树形菜单: using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebCo

DataTable转化为List

public List<T> ConvertToList<T>(DataTable dt) where T : new() { // 定义集合 List<T> ts = new List<T>(); // 获得此模型的类型 Type type = typeof(T); string tempName = "";

C#无限级分类递归显示示例

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RoleDemo20150305.aspx.cs" Inherits="RoleDemo20150305" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.

C#递归生成HTML树，C#递归生成xml树

C#递归生成HTML树 public StringBuilder str = new StringBuilder(); //定义一个字符串 private void get_navigation_childs(List<TableClass> oldData, string parent_id) { List<TableClass> dr = oldData.Where(x => x.PCode == parent_id).OrderBy(x => x.Kid).T

c#中@标志的作用 C#通过序列化实现深表复制细说并发编程-TPL 大数据量下DataTable To List效率对比【转载】C#工具类：实现文件操作File的工具类异步多线程 Async .net 多线程 Thread ThreadPool Task .Net 反射学习

c#中@标志的作用参考微软官方文档-特殊字符@,地址 https://docs.microsoft.com/zh-cn/dotnet/csharp/language-reference/tokens/verbatim 1.在变量名前加@,可以告诉编译器,@后的就是变量名.主要用于变量名和C#关键字重复时使用. string[] @for = { "John", "James", "Joan", "Jamie" }; fo
