基于AD的用户组织目录树选择工具的解决方案

本文的需求来自进来SharePoint开发中的人员选择,基础中国的用户更加喜欢通过组织结构来选择人员,这样可以清晰的知道选择人员的部门,通过组织结构选择人员是本文的讨论点。

我也是集合了前人的思路,进行了整合,参考了下面的博客

 asp.net(C#)弹出窗口返回值并刷新主窗体

使用C#中的DirectorySearcher来获得活动目录中的组织结构与用户等信息,并在展示成树形结构(附源代码)

感谢三位作者的无私奉献,为我的这篇博客提供了资料。

   我的整个实现是由三个页面组成,首先是一个信息填写页面WebForm1.aspx,有一栏为选择任务的执行人员
showModalDialog1.JPG

WebForm1.aspx页面代码如下

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApp.WebForm1" %>

<!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>无标题页</title>
    <style type="text/css">
        body
        { font-size:12px;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <table style=" 100%;">
            <tr>
                <td style="100px;">
                    任务标题:</td>
                <td>
                    
                    <asp:TextBox ID="TextBox2" runat="server" Width="500px"></asp:TextBox>
                </td>
              
            </tr>
            <tr>
               <td style="100px;">
                    
                    任务内容:</td>
                <td>
                    
                    <asp:TextBox ID="TextBox3" runat="server" Height="117px" TextMode="MultiLine" 
                        Width="500px"></asp:TextBox>
                </td>
                
            </tr>
            <tr>
               <td style="100px;">
                   
                    代办人:</td>
                <td>
                   <asp:TextBox ID="TextBox1" runat="server" Width="500px">这是初始值,将被传递到新窗口。</asp:TextBox>
        
            <asp:Button ID="Button1" runat="server" Text="打开窗口" Width="96px" 
             onclick="Button1_Click" />
                </td>
               
            </tr>
        </table>
        
    </div>
    </form>
</body>
</html>

WebForm1.aspx的后台代码如下


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.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

namespace WebApp
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!ClientScript. IsClientScriptBlockRegistered("clientScript"))
            {
                System.Text.StringBuilder sbScript = new System.Text.StringBuilder();
                sbScript.Append("<script>");
                sbScript.Append("function OpenWin(){");
                sbScript.Append(Environment.NewLine);
                sbScript.Append("var str=window.showModalDialog('WebForm2.aspx',document.form1.TextBox1.value,'dialogWidth=800px;dialogHeight=700px','scroll:yes');");
                sbScript.Append(@"if(str!=null)
                    {
                        var users=str;
                        document.form1.TextBox1.value=users.substring(0,users.lastIndexOf(','));
                    }
                    ");
                sbScript.Append("}");
                sbScript.Append("</script>");
                ClientScript. RegisterClientScriptBlock(this.GetType(),"clientScript", sbScript.ToString());
            }
            Button1.Attributes.Add("onclick", "OpenWin()");
        }

        protected void Button1_Click(object sender, EventArgs e)
        {

        }
    }
}


弹出窗口如下图,是用一个页面,里面嵌套一个iframe,防止回发之后页面消失WebForm2.aspx嵌套ADOperTest.aspx

WebForm2.aspx页面文件,没有后台代码

   这个东西本来是SharePoint开发过程中出来的需求,可是返回的只是一个组合了用户姓名的字符串,不能变成SPUser对象,SPUser对象又没有构造函数,有没有研究过这个呢,如果有的话,可以给我留言,谢谢了。
