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

  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
