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

  1   /// <summary>
  2         /// 绑定Tree
  3         /// </summary>
  4         /// <returns></returns>
  5         private DataSet GetDataSet()
  6         {
  7             CommUserBLL bll = new CommUserBLL();
  8             DataSet ds = bll.GetAllList();
  9 
 10             foreach (DataRow row in ds.Tables[0].Rows)
 11             {
 12                 FineUI.TreeNode node = new FineUI.TreeNode();
 13                 if (row.IsNull("PersonGroupID"))
 14                 {
 15                     node.Text = row["CompName"].ToString();
 16                     node.IconUrl = "~/icon/star.png";
 17                     node.Expanded = true;
 18                     node.EnableCheckBox = true;
 19                     node.EnablePostBack = true;
 20                     node.AutoPostBack = true;
 21                     Tree1.Nodes.Add(node);
 22                     LoadTree(node);
 23                 }
 24             }
 25             return ds;
 26         }
 27
