ASP. Net advanced: SiteMapPath, TreeView

Understand the SiteMapPath control. The SiteMapPath data comes from the site map file. Note: Only pages listed in the site map can display navigation data in the SiteMapPath control. If you place the SiteMapPath control on a page not listed on the site map, the control does not display any information to the client. Example: The dynamic Web page used: Add a SiteMapPath control on each page and add a Web. sitemap site map file. In the site map, <siteMap xmlns =" http://schemas.microsoft.com/AspNet/SiteMap-File-1.0 "> <SiteMapNode url =" default1.aspx "title =" Homepage "description =" "> <siteMapNode url =" tiyu. aspx "title =" Sports "description =" click to enter sports "> <siteMapNode url =" Guoneitiyu. aspx "title =" domestic sports "description =" "/> <siteMapNode url =" aoyunhui. aspx "title =" Olympics "description =" "/> <siteMapNode url =" zuqiu. aspx "title =" "description =" "/> </siteMapNode> <siteMapNode url =" caijin. aspx "title =" finance "description =" "> <siteMapNode Url = "gupiao. aspx "title =" stock "description =" "/> <siteMapNode url =" dichan. aspx "title =" "description =" "/> </siteMapNode> <siteMapNode url =" qiche. aspx "title =" "description =" "/> </siteMapNode> </siteMap> the TreeView control displays navigation information in a tree structure, you can control the style and behavior of each node in the number. When a program is used to dynamically fill the TreeView control, recursion is generally required. Example: The dynamic web page used: 1ASPDotNet. aspx2java. aspx3php. aspxdefault. aspxDemo2.aspxindex. aspxjavaTerm1.aspx adds a TreeView control (select the data source SiteMapDataSource1) and SiteMapDataSource data source on each page, and adds a Web. sitemap: <siteMap xmlns =" http://schemas.microsoft.com/AspNet/SiteMap-File-1.0 "> <SiteMapNode url =" default. aspx "title =" Homepage "description =" "> <siteMapNode url =" 1ASPDotNet. aspx "title =" Net direction "description =" "> <siteMapNode url =" NetTerm1.aspx "title =" Net direction first semester "description =" "> <siteMapNode url =" NetTerm1C1. aspx "title =" first semester course 1htmlcss and js "description =" "/> <siteMapNode url =" NetTerm1Course2. aspx "title =" first semester course 2C # "description =" "/> </siteMapNode> <siteMapNode url =" NetTerm2.aspx "title =" Net to second semester "description = "" /> </siteMapNode> <siteMapNode url = "2java. aspx "title =" Java direction "description =" "> <siteMapNode url =" javaTerm1.aspx "title =" java direction first semester "description =" "/> <siteMapNode url =" JavaTerm2.aspx "title =" java to the second semester "description =" "/> </siteMapNode> <siteMapNode url =" 3php. aspx "title =" Php direction "description =" "/> </siteMapNode> </siteMap>
