so I decided to help them all out, but I don’t want to fill the blogsphere with another post of LINQ, WPF or WCF, because its already filled with a lot of articles on them by geek’s and various people around the world.so what I’m going to do is post some valuable links on where you can give a kick start on learning these.

1. To get visual studio 2008 read the post here.
2. The first and best place I would recommend to learn is reading Scott Guthrie’s web blog. he had written some excellent articles on these new technologies. I would recommend you to subscribe his blogs feeds or book marking his blog for future reference. here is are some valuable articles by him.

4. And now for WPF. here are the web sites which helped me to build my WPF knowledge.

   2. The Content Presenter
   3. The WPF Blog
5. And so far to lean Silverlight would recommend the official Silverlight web site.

7. And finally The Official Visual studio 2008 training kit by Microsoft

Well These are the sites which I visit often to learn about these new technologies. I’m just sharing these with you to make it easy to find about these and learn them easily without spending much time to search for these.

I hope it helped you, Enjoy!!.

But we can write our own custom methods in your classes to Achieve this requirement, by looking at the SiteMapNode based on its title or URI. a sample is given below:

   1:  private string menuDescription=string.Empty;

   2:   

   3:  protected string GetDescriptionByTitle(string title)

   4:  {

   5:  /*this assumes that there is only one node with this title.

   6:  which is a standard in asp.net SiteMap Development*/

   7:   

   8:  SiteMapNode node = SiteMap.RootNode;

   9:  SearchForDesc(node, title);

  10:  return menuDescription;

  11:  }

  12:   

  13:  private void SearchForDesc(SiteMapNode node,string title)

  14:  {

  15:  if (node.Title == title)

  16:  {

  17:  menuDescription = node.Description;

  18:  return;

  19:  }

  20:  else

  21:  {

  22:  foreach (SiteMapNode childnode in node.ChildNodes)

  23:  {

  24:  //search within childnodes

  25:  SearchForDesc(childnode, title);

  26:  }

  27:  }

  28:  }

And we can use the StaticItemTemplate and the DynamicItemTemplate to Display this information and use the GetDescriptionByTitle() method inside the templates as given below:

<asp:Menu ID="Menu1" runat="server" Height="24px"
Width="109px" DataSourceID="SiteMapDS1" StaticDisplayLevels="2"
StaticSubMenuIndent="0px">
<StaticItemTemplate>    <%# Eval("Text") %> <br />
<small>
<%# GetDescriptionByTitle(((MenuItem)Container.DataItem).Text) %>
</small></StaticItemTemplate><DynamicItemTemplate>
<%# Eval("Text") %> <br />   <small>
<%# GetDescriptionByTitle(((MenuItem)Container.DataItem).Text) %>
</small></DynamicItemTemplate></asp:Menu>

And here is the output:

Hope it helps!.
