求帮助，怎么在web part 页中插入左侧导航

求帮助，如何在web part 页中插入左侧导航？
在创建一个新的页面的时候，可以创建Wiki的页面，直接就有左侧导航，可是如果一个Web part 页就是空白的，怎么添加呢。

还有个问题就是如果自己在designer里点击“Advanced Mode” 去编辑代码， 该网页就有Important StatusThe current page has been customized from its template的提示， 如何去掉呢？


谢谢大侠们！

1. 可以在WebPart页面中添加Sharepoint:SPNavigationManager：

	<Sharepoint:SPNavigationManager
				id="QuickLaunchNavigationManager"
				runat="server"
				QuickLaunchControlId="QuickLaunchMenu"
				ContainedControl="QuickLaunch"
				EnableViewState="false"
				CssClass="ms-quicklaunch-navmgr">
				<div>
					<SharePoint:DelegateControl runat="server" ControlId="QuickLaunchDataSource">
						<Template_Controls>
						<asp:SiteMapDataSource SiteMapProvider="SPNavigationProvider" ShowStartingNode="False" id="QuickLaunchSiteMap" StartingNodeUrl="sid:1025" runat="server" />
					 </Template_Controls>
					</SharePoint:DelegateControl>
					<SharePoint:UIVersionedContent UIVersion="3" runat="server">
						<ContentTemplate>
							<SharePoint:AspMenu id="QuickLaunchMenu" runat="server" DataSourceId="QuickLaunchSiteMap" Orientation="Vertical" StaticDisplayLevels="2" ItemWrap="true" MaximumDynamicDisplayLevels="0" StaticSubMenuIndent="0" SkipLinkText="" CssClass="s4-die">

									<asp:menuitemstyle CssClass="ms-selectednav" />
								</LevelSelectedStyles>
							</SharePoint:AspMenu>
						</ContentTemplate>
					</SharePoint:UIVersionedContent>
					<SharePoint:UIVersionedContent UIVersion="4" runat="server">

						</ContentTemplate>
					</SharePoint:UIVersionedContent>
				</div>
				</Sharepoint:SPNavigationManager>
			<Sharepoint:UIVersionedContent runat="server" UIVersion="3">
