I've run into an issue where calling SiteMap.CurrentNode returns null when it really shouldn't be. I'm using SiteMap.CurrentNode to highlight certain buttons on the page and generate a sub navigation bar (through SiteMap.CurrentNode.ChildNodes).
Now this works until I attempt to get to my pages of which are generated by a dynamic provider. For some reason whenever I attempt this on my Projects page SiteMap.CurrentNode returns null. Overall this is a bad situation for my program because then I cant generate my sub-navigation bar.
I was hoping someone here might be able to figure out the fault in my Sitemap or provider so that I can do a basic tutorial to others who are attempting the same thing since I haven't seen a tutorial that implements a provider in the manner that I have.
Web.SiteMap:
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/Default.aspx" title="Home" description="Home page where updates and other information can be found">
<siteMapNode provider="ProjectProvider" />
<siteMapNode url="~/Contact/Default.aspx" title="Contacts" description="Contacts" />
</siteMapNode>.......
Provider:
Implements the following methods and all of them do not return Null (I checked via debug):
- RootNode
- GetRootNodeCore
- Initialize
- Clear
- BuildSiteMap

I have a SiteMap navigation using an asp:repeater control databound to a SiteMapDataSource. The repeater contains an asp:hyperlink for each node, and the CssClass is explicitly defined:
[Code]....
How would I cause the item that corresponds to the current node on the sitemap tree to have a different CssClass? I've had a few unsuccessful attempts (stab in the dark in all honesty) using the ItemDataBound event handler and inline code.

I have a long alphabetical list to be displayed by a gridview.
I need to have links at the top of the page that will link to anchors in the gridview. How can I get anchor tags in the gridview so that the links will jump to them when clicked?

I've added a subarea to my sitemap in CRM 4.0, and for absolute URLs it works as expected. However, for relative URLs it does not. The page in question is internal and is accessed through:
http://localhost/ISV/<orgName>/Account.aspx/ExternalDocumentList
However, I would prefer writing this in sitemap:
/ISV/<orgName>/Account.aspx/ExternalDocumentList
When this is expanded, CRM/IIS rewrites it to:
http://localhost/<orgName>/ISV/<orgName>/Account.aspx/ExternalDocumentList
For reference, here is the sitemap addition (which doesn't work):
<SubArea Id="custom_documentHistory" Url="/ISV/<orgName>/Account.aspx/ExternalDocumentList">
<Titles>
<Title LCID="1033" Title="Document History"/>
</Titles>
</SubArea>
How can I link to this page relatively?

I have a intranet site with Windows Authentication. I have 'Administrator' pages in an 'Administrator' folder that will only show for those in the admin group (windows security group) These pages work
I have a folder with sub folders containing reports. These permissions are broken down for each type of report. They have similar role priveleges. When I test the application, I can navigate to the pages. When I deploy the site live on the intranet the links don't return a page. Error missing link 404. Do I need to set something in IIS?

I've noticed that when i switch (browse) in between internal links in mywebsite "about", "services", "home", "contact", using Mozilla Firefox browser pages are moving slightly from one side to the other.(right to left and vice versa)
Tried the same in Explorer and it's fine. Any ideas why that is happening and how to fix it?

I've been having some production runtime errors that I don't fully understand. This has happened to us on a couple different ASP.NET 4.0 Web Sites (shudders - yes, I know - we're porting it to MVC but that's taking some time).
First of all, we have never been able to reproduce this issue in development/QA environments. Secondly, upon deployment, the issue seems to be non-existent. Sometimes the issue manifests within a day or two of deployment and other times the deployment will be live for a month without it manifesting at all. However, once it manifests, then ANY page viewed under the web site causes the error. Lastly, this problem seemed to only come up once we migrated to .NET 4.0. We started at 2.0, a year ago upped to 3.5, and recently upped to 4.0 with this solution and most child projects.
The error:
Could not find the sitemap node with URL '~/Default.aspx'.
A simplified version of our sitemap (with some names changed and uninteresting nodes removed) is as follows:
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
<siteMapNode roles="*" title="EG">
<siteMapNode url="~/../SM/Default.aspx" title="Welcome" description="" roles="*" />
<siteMapNode url="~/../SD/Default.aspx" title="SD" description="" roles="*" />
<siteMapNode url="~/../SMD/Default.aspx" title="SMD" description="" roles="*" />
[code]...
I have confirmed in all of the SiteMaps that there is a node with url="~/Default.aspx" with roles="*" (which includes public/anonymous access), so I am very confused as to why this problem occurs.
SiteMap does not have a node for Default.aspx. All of them do. SiteMap's Default.aspx node is not accessible for security reasons to the current user/role. They're all accessible to anonymous users and this problem even exists for super admin users. Passed-in URL contains querystrings (Default.aspx?abcd). I don't know if this is a problem (I sure would hope not) but once the problem manifests itself, I can handwrite the URL with no querystrings and the problem still exists.
SiteMap changes. It doesn't Service's permissions to the sitemap file. The sitemap works perfectly fine after a deployment, so unless permissions are changed in a way that IISRESET fixes, then this is not an issue. The worker process becomes globally corrupt. I don't think so. We have ~12 web sites all in the same app pool and the problem always stays confined within a single web site. Also, we have yet to have this happen to more than a single web site at a time although it has manifested itself in 4 different ones so far.

I've got a custom menu navigation built from a web.sitemap file, the first line of this would be something like:
SiteMapNodeCollection topLevelNodes = SiteMap.RootNode.ChildNodes;
However, now I want to be able to create multiple web.sitemap files, and then programmatically determine which web.sitemap file to use, but I can't seem to find out how to do this. I'm assuming I could either create one custom SiteMapProvider that can perform the logic to determine which web.sitemap file to load, or I have multiple providers, each one with the SiteMapFile property set to a specific *.sitemap file, and then switch providers programmatically before I access SiteMap.RootNode.

How would I programatically reference a .sitemap file that is not the root web.sitemap file? I have a file called research.sitemap in a folder a level under root. I want to refernce this file in my code behind like his: SiteMapNode m1 = SiteMap.RootNode (but since this isnt web.sitemap in the root, I dont know how to get access to it).

I am creating a CacheDependency on the file that my SiteMap provider uses. I would like to get the name of the file from my sitemap provider instead of hard coding it. Is there a way?

Duh, I forgot to mention: XmlSiteMapProvider that comes with ASP.NET
Edit 2
Reflector shows a private member field called _filename that isn't exposed in any way as far as I can tell.

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

I have a problem with a SessionVariable. I will explain what is happening:
1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !
2. In the Page_Load, I later fill a ListBox1 with foldernames.
3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)
The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?
if (Session["LoginByAdmin"] == null)
Response.Redirect("Default.aspx");
break;

I need to set some values before the menu item navigates to the page. I'd like to use the same aspx page for more than one menu item and I'd like to avoid the use of querystrings in my code. However, I realize that it's not possible to set the same url in the web.sitemap file. If I don't specify a url, the menu item created is not click-able.
