數據綁定到TreeView

TreeView命名爲tvMonitorySite,導入using System.Data.SqlClient

protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { BindTreeView(tvMonitorySite, true, "1", ""); } } /// <summary> /// 綁定TreeView /// </summary> /// <param name="treeview">控件TreeView</param> /// <param name="isExpend">是否展開</param> /// <param name="sSelectData">默認選中的節點</param> /// <param name="roleId">角色ID</param> public void BindTreeView(TreeView treeview,bool isExpend,string sSelectData,string roleId ) { string sqlSelect="SELECT [ID],[Text],[Url],[IconCls],[ParentID] FROM [Menu]"; DataTable dataTable = DBHelper.GetDataTable(sqlSelect, CommandType.Text, null); treeview.Nodes.Clear(); TreeNode root = new TreeNode(); root.Text = "導航菜單列表"; root.Value = "0"; root.ShowCheckBox = true; root.Selected = true; root.Expanded = isExpend; root.Checked = true; treeview.Nodes.Add(root); CreateChildNode(dataTable, root, isExpend, sSelectData); } /// <summary> /// 創建子節點 /// </summary> /// <param name="dataTable">DataTable</param> /// <param name="parentNode">父結點</param> /// <param name="isExpend">是否展開</param> /// <param name="sSelectData">默認選中的節點</param> private void CreateChildNode(DataTable dataTable,TreeNode parentNode,bool isExpend,string sSelectData) { DataRow[] rowList = dataTable.Select("ParentID=" + parentNode.Value); foreach (DataRow row in rowList) { TreeNode node = new TreeNode(); node.Text = row["Text"].ToString(); node.Value = row["ID"].ToString(); node.ShowCheckBox = true; node.Expanded = isExpend; if (node.Value==sSelectData) { node.Selected = true; } parentNode.ChildNodes.Add(node); CreateChildNode(dataTable, node, isExpend, sSelectData); } }
