ASP.NET组织结构图的画法——数据来源读取数据库

今天整整忙了一天，终于给这个组织结构图画出来了

第一：数据库部分：

ID主键ID

Name 组织结构名称

FavID 父组织ID

主要是这三个字段  若是没有父组织，则父组织给FavID=0

第二：添加一个开源的dll：Whidsoft.WebControls.OrgChart.dll下载地址：点击下载控件源码

下载后生成一个dll放到项目中就可以使用了，下面是使用方法

第三：静态使用方法

前台页面：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<%@ Register TagPrefix="oc" Namespace="Whidsoft.WebControls" Assembly="Whidsoft.WebControls.OrgChart" %>

protected void Page_Load(object sender, EventArgs e)
    {
        string style = Request.QueryString["style"];

            if (style == null || style == "")

            }

                OrgNode3.Nodes.Add(OrgNode32);
                OrgNode3.Nodes.Add(OrgNode33);
                orgNode.Nodes.Add(OrgNode3);

                OrgNode OrgNode4 = new OrgNode();

                OrgNode41.Description = "这是3";

                OrgNode OrgNode42 = new OrgNode();
                OrgNode42.Text = "商业";
                OrgNode42.Description = "这是3";

                OrgNode OrgNode43 = new OrgNode();
                OrgNode43.Text = "机房";
                OrgNode43.Description = "这是3";

                OrgNode4.Nodes.Add(OrgNode41);
                OrgNode4.Nodes.Add(OrgNode42);
                OrgNode4.Nodes.Add(OrgNode43);
                orgNode.Nodes.Add(OrgNode4);

                OrgChart1.Node = orgNode;

                OrgChart1.ChartStyle = (style == "1") ? Whidsoft.WebControls.Orientation.Vertical : Whidsoft.WebControls.Orientation.Horizontal;
            }
    }

或者是动态读取数据库方式，这里前台部分不需要改动，只需要后台些方法就好，主要是一个递归的方法

private void Bind()
    {
        string style = Request.QueryString["style"];

        if (style == null || style == "")
        {
            style = "1";
        }

        //1.数据查询
        Hashtable ht = new Hashtable();
        ht.Add("FavHROID", 0);
        IList<HROrganization> HROLst = HROrganizationService.GetInstance().FindAll(ht);
        OrgNode orgNode = new OrgNode();
        orgNode.Text = HROLst[0].Name;
        
        Hashtable ht1 = new Hashtable();
        ht1.Add("FavHROID", HROLst[0].ID);

        AddNode(ht1, orgNode);
        OrgChart1.Node = orgNode;

        OrgChart1.ChartStyle = (style == "1") ? Whidsoft.WebControls.Orientation.Vertical : Whidsoft.WebControls.Orientation.Horizontal;
        
    }
    /// <summary>
    /// 给节点赋值
    /// </summary>
    /// <param name="ht1"></param>
    /// <param name="orgNode"></param>
    private void AddNode(Hashtable ht1, OrgNode orgNode)
    {
        IList<HROrganization> HROLst2 = HROrganizationService.GetInstance().FindAll(ht1);
        foreach (HROrganization item2 in HROLst2)
        {
            OrgNode OrgNode2 = new OrgNode();
            OrgNode2.Text = item2.Name;
            orgNode.Nodes.Add(OrgNode2);
            Hashtable ht2 = new Hashtable();
            ht2.Add("FavHROID", item2.ID);
            AddNode(ht2, OrgNode2);
        }
    }

希望对大家稍有帮助
