FineUI控件之树的应用(二)

一、Tree控件应用

  <f:PageManager ID="PageManager1" runat="server" />
        <f:Tree ID="Tree1" Width="650px" ShowHeader="true" Title="树控件" EnableFrame="true" EnableCollapse="true"
            runat="server">
            <Nodes>
                <f:TreeNode Text="中国" Expanded="true">
                    <f:TreeNode Text="111" Expanded="true">
                        <f:TreeNode Text="222" NodeID="zhumadian">
                            <f:TreeNode Text="333" Leaf="false" NodeID="suiping">
                                <f:TreeNode Text="444" Leaf="false" NodeID="huaishu">
                                    <f:TreeNode Text="555" NodeID="chenzhuang">
                                    </f:TreeNode>
                                </f:TreeNode>
                            </f:TreeNode>
                        </f:TreeNode>
                        <f:TreeNode Text="666" NodeID="luohe" />
                    </f:TreeNode>
                    <f:TreeNode Text="777" Expanded="true" NodeID="anhui">
                        <f:TreeNode Text="888" Expanded="true" NodeID="hefei">
                            <f:TreeNode Text="999" NodeID="golden">
                            </f:TreeNode>
                            <f:TreeNode Text="000" NodeID="ustc">
                            </f:TreeNode>
                        </f:TreeNode>
                    </f:TreeNode>
                </f:TreeNode>
            </Nodes>
        </f:Tree>

二、后台代码 动态生成Tree 帮定数据库

   /// <summary>
         /// 绑定Tree
         /// </summary>
         /// <returns></returns>
         private DataSet GetDataSet()
         {
             CommUserBLL bll = new CommUserBLL();
             DataSet ds = bll.GetAllList();

             foreach (DataRow row in ds.Tables[].Rows)
             {
                 FineUI.TreeNode node = new FineUI.TreeNode();
                 if (row.IsNull("PersonGroupID"))
                 {
                     node.Text = row["CompName"].ToString();
                     node.IconUrl = "~/icon/star.png";
                     node.Expanded = true;
                     node.EnableCheckBox = true;
                     node.EnablePostBack = true;
                     node.AutoPostBack = true;
                     Tree1.Nodes.Add(node);
                     LoadTree(node);
                 }
             }
             return ds;
         }

         /// <summary>
         /// 加载子节点
         /// </summary>
         /// <param name="treeNode"></param>
         private void LoadTree(FineUI.TreeNode treeNode)
         {
             CommUserBLL bll = new CommUserBLL();
             DataSet dept = bll.GetDepetName();
             foreach (DataRow row in dept.Tables[].Rows)
             {
                 FineUI.TreeNode node2 = new FineUI.TreeNode();
                 node2.Expanded = true;
                 node2.EnableCheckBox = true;
                 node2.EnablePostBack = true;
                 node2.AutoPostBack = true;
                 node2.IconUrl = "~/icon/star.png";
                 node2.Text = row["DeptName"].ToString();

                 treeNode.Nodes.Add(node2);
                 LoadPerson(row, node2);
             }
         }

         /// <summary>
         /// 加载叶子节点

             StringBuilder str = new StringBuilder();
             DataSet deptPerson = bll.GetList("  deptname = '" + dr["DeptName"].ToString() + "'");
             foreach (DataRow row in deptPerson.Tables[].Rows)
