web.sitemap, AspNet Sitemap Providers and UltimateSitemap
I've been using UltimateSitemap (USM) on a client project and have a mixed bag of success and frustration. Achieving simple success using the AspNet web.sitemap file was not overly difficult. One annoyance is that the XML namespace attribute of the sitemap's 'siteMap' node seems to break USM.

<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">

With this attribute intact USM prodiuces no errors or output. The USM designer does not seem to work correctly either, clicking on a node to edit its position or cssclass causes the window to close without notification.

Removing the namespace reference fixes USM, the designer works and the component produces the expected output. Unfortunately with the attribute removed Visual Studio 2005 (VS05) will no longer offer syntax hints. This became a minor annoyance once I figured out the problem, though I would prefer to see an update that allows USM to work with this attribute intact.

Any comment in the web.sitemap will prevent USM from opening the designer with a somewhat cryptic error merssage:
'Object reference not set to an instance of an object'
Again, not the end of the world but a bit aggrevating until you figure out what is going on.

My site has sections that I have additional SitemapProviders configured to handle; web.sitemap includes these with SiteMapNodes using the Provider or siteMapFile attributes to pull in the various child nodes from the other providers. USM does not seem to support this functionality. It does 'fail gracefully' in that it does display all the other nodes, the provider node just shows up empty, even without a nodeId.

My workaround at this time is looking like I will iterate over the nodes of the root SiteMapProvider and build an XML string that I will pass to USM. (I might do it in a cooler way that that but you get the basic idea). USM performs perfectly well with XML strings, haven't had any problems with hooking it up to an XmlDataProvider (which is also incapable of following the provider nodes in a sitemap file); so, I do expect that this issue can be worked around without a lot of programming.

I can't fault USM for not following these provider nodes, since USM only claims to interpret XML and  not AspNet SiteMapProviders (big difference), but I would like to add the abillity to hook up USM to a sitemapprovider to the feature wish list.

Is there a recomendation regarding the handling of providers?


Overall I'm so far pleased with UISuite, its a nice suite for the price.
UltimateSearch is the best value so far in my opinion, it was the search component that 'Ultimately' convinced me to recommend picking up the UISuite.

Re: web.sitemap, AspNet Sitemap Providers and UltimateSitemap
Thank you for all your comments and feedback. We will look into some of the issues such as breaking with comments, but we're not planning to do any further improvement for data providers at this point. However, we will add all your points into our enhancements list for future reference.

Re: web.sitemap, AspNet Sitemap Providers and UltimateSitemap

My workaround, which anyone is welcome to try out or modify for their needs is posted below. This code segment is by no means ideal or robust, but it is enough to get me over the current hump.

One item that is frustrating about working with SiteMapNodes is that there seems to be no way to list all attributes in a sitemapnode object. SiteMapNodeAttributeList below provides the workaround for this, you have to explicitly state the attributes you want transposed to the output xml. In the case of UltimateSitemap I feed the list of UltimateSitemap specific variables. Attributes not present in the source will not be output.

The listing below will start from the SiteMap RootNode and map SiteMapNodes to XML Nodes through recursion. This will produce output that incorporates additional SiteMapProviders included in the web.sitemap.

This works well in my present scenario, larger implementations may want to incorporate caching - for now I'm using the heavy handed aproach of generating the output with each call.

Re: web.sitemap, AspNet Sitemap Providers and UltimateSitemap
ok then. I'm obviously having some technical problems with posting my code.

Imports Microsoft.VisualBasic

Public Class AspNetSiteMapXmlDocumentAdapter

Private _XmlDocument As System.Xml.XmlDocument

Private _SiteMapNodeAttributeList As New ArrayList

Private XmlTextWriter As System.Xml.XmlTextWriter

Public ReadOnly Property XmlDocument() As System.Xml.XmlDocument


XmlDocument = _XmlDocument

End Get

End Property

ReadOnly Property XmlString() As String


XmlString = XmlDocument.OuterXml

End Get

End Property


Public Property SiteMapNodeAttributeList() As ArrayList


SiteMapNodeAttributeList = _SiteMapNodeAttributeList

End Get

Set(ByVal AttributeArrayList As ArrayList)

_SiteMapNodeAttributeList = AttributeArrayList

End Set

End Property


Sub Execute()

Dim StringWriter As New System.IO.StringWriter

Dim SiteMapNode As SiteMapNode = SiteMap.RootNode

XmlTextWriter = New System.Xml.XmlTextWriter(StringWriter)








_XmlDocument = New System.Xml.XmlDocument




End Sub

Private Sub SiteMapNodeToXMLNodeRecursion(ByVal SiteMapNode As SiteMapNode)


XmlTextWriter.WriteAttributeString("url", SiteMapNode.Url)

XmlTextWriter.WriteAttributeString("title", SiteMapNode.Title)

XmlTextWriter.WriteAttributeString("description", SiteMapNode.Description)

If SiteMapNode.Roles.Count > 0 Then

Dim SiteMapNodeRoles As String = ""

Dim Role As String

For Each Role In SiteMapNode.Roles

SiteMapNodeRoles = SiteMapNodeRoles & Role & ","


SiteMapNodeRoles = Left(SiteMapNodeRoles, Len(SiteMapNodeRoles) - 1)

XmlTextWriter.WriteAttributeString("Roles", SiteMapNodeRoles)

End If

If SiteMapNode.ResourceKey <> "" Then

XmlTextWriter.WriteAttributeString("ResourceKey", SiteMapNode.ResourceKey)

End If

If _SiteMapNodeAttributeList.Count > 0 Then

Dim SiteMapAttribute As String

For Each SiteMapAttribute In _SiteMapNodeAttributeList

If SiteMapNode.Item(SiteMapAttribute) <> "" Then

XmlTextWriter.WriteAttributeString(SiteMapAttribute, SiteMapNode.Item(SiteMapAttribute))

End If


End If

If SiteMapNode.HasChildNodes = True Then

Dim ChildSiteMapNode As SiteMapNode

For Each ChildSiteMapNode In SiteMapNode.ChildNodes



End If


End Sub


End Class


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Dim Adapter As New AspNetSiteMapXmlDocumentAdapter














UltimateSitemap1.SitemapSourceXml = Adapter.XmlString

End Sub
