How to Populate menu using sitemap and asp .net menu control and c#:

Depending on your requirements you can populate the tree view control using different sources.

Here I give the example for populating the asp .net menu using sitemap.
private void CreateMenuControl()
{

Menu1.DataSource = GetSiteMapDataSource();
Menu1.DataBind();

}

private SiteMapDataSource GetSiteMapDataSource()
{
XmlSiteMapProvider xmlSiteMap = new XmlSiteMapProvider();
System.Collections.Specialized.NameValueCollection myCollection = new System.Collections.Specialized.NameValueCollection (1);
myCollection.Add("siteMapFile", "Web.sitemap");
xmlSiteMap.Initialize("provider", myCollection);
xmlSiteMap.BuildSiteMap();

SiteMapDataSource siteMap = new SiteMapDataSource();

return siteMap;
}

Copy the following code in to your sitemap,

And copy the following code in to your master page,

And create the following pages as content pages in your master page.

Main.aspx
Menu1.aspx
Menu2.aspx
SubMenu1.aspx

Then run the project….that’s it…
