創建表及插入模擬數據：
CREATE
TABLE [sysMenuTree]( |
[NoteId] [decimal](18, 0)
NOT NULL,
|
[ParentId] [decimal](18, 0)
NULL, |
[sText] [nvarchar](50) NULL,
|
[sValue] [nvarchar](50) NULL,
|
[sURL] [nvarchar](50) NULL,
|
[sTarget] [nvarchar](50) NULL,
|
[Chger] [nvarchar](50) NULL,
|
[ChgTime] [nvarchar](50) NULL）
|
insert
into sysMenuTree values(3,0,N'目錄',N'目錄','','','','')
|
insert
into sysMenuTree values(4,0,N'目錄',N'目錄','','','','')
|
insert
into sysMenuTree values(5,0,N'目錄',N'目錄','','','','')
|
insert
into sysMenuTree values(6,3,N'項目.1',N'項目.1','','','','')
|
insert
into sysMenuTree values(7,3,N'項目.2',N'項目.2','','','','')
|
insert
into sysMenuTree values(8,4,N'項目.1',N'項目.1','','','','')
|
insert
into sysMenuTree values(9,4,N'項目.2',N'項目.2','','','','')
|
insert
into sysMenuTree values(10,4,N'項目.3',N'項目.3','','','','')
|
insert
into sysMenuTree values(11,5,N'項目.1',N'項目.1','','','','')
|
insert
into sysMenuTree values(12,5,N'項目.2',N'項目.2','','','','') |
在ASP.NET中讀取數據綁定到TreeView實現代碼：
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
%> |
<form id="form1"
runat="server">
|
<asp:TreeView ID="treeMenu"
runat="server">
|
using
System.Web.UI.WebControls; |
using
System.Data.SqlClient; |
public
partial class
_Default : System.Web.UI.Page |
private
readonly string
ConnString = @"server=.\MSSQLSERVER2008;database=chart;uid=sa;pwd=123456";
|
private
DataTable dt = null;
|
protected
void Page_Load(object
sender, EventArgs e) |
GetMenuToDataTable("select * from sysMenuTree",dt);
|
private
void BindTree(DataTable dtSource,TreeNode parentNode,string
parentID) |
DataRow[] rows = dtSource.Select(string.Format("ParentID={0}",parentID));
|
foreach(DataRow row
in rows)
|
TreeNode node =
new TreeNode();
|
node.Text = row["sText"].ToString();
|
node.Value = row["sValue"].ToString();
|
BindTree(dtSource,node,row["NoteId"].ToString());
|
treeMenu.Nodes.Add(node);
|
parentNode.ChildNodes.Add(node);
|
private
DataTable GetMenuToDataTable(string
query,DataTable dt) |
using(SqlConnection conn =
new SqlConnection(ConnString))
|
SqlCommand cmd =
new SqlCommand(query,conn);
|
SqlDataAdapter ada =
new SqlDataAdapter(cmd);
