生成Treeview树 递归方法

产生树的效果图


aspx页面

<asp:TreeView ID="tv" runat="server" ImageSet="Arrows" LineImagesFolder="~/TreeLineImages" OnSelectedNodeChanged="tv_SelectedNodeChanged" OnTreeNodeCheckChanged="tv_TreeNodeCheckChanged" OnTreeNodeCollapsed="tv_TreeNodeCollapsed" OnTreeNodeDataBound="tv_TreeNodeDataBound" OnTreeNodeExpanded="tv_TreeNodeExpanded" OnTreeNodePopulate="tv_TreeNodePopulate">
                <ParentNodeStyle Font-Bold="False" />
                <HoverNodeStyle Font-Underline="True" ForeColor="#5555DD" />
                <SelectedNodeStyle Font-Underline="True" ForeColor="#5555DD" HorizontalPadding="0px"
                    VerticalPadding="0px" />
                <NodeStyle Font-Names="Verdana" Font-Size="8pt" ForeColor="Black" HorizontalPadding="5px"
                    NodeSpacing="0px" VerticalPadding="0px" />
            </asp:TreeView>

生成树的递归方法

public void RecursionUser(string strUserID, TreeNodeCollection NodeParent)
    }

调用递归方法 生成树

   RecursionUser(NULL_GUID, tv.Nodes);
