Web Forms :: SiteMap.CurrentNode Returns Null For Internal SiteMapProvider?

Mar 7, 2010

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.


<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" />


Implements the following methods and all of them do not return Null (I checked via debug):
- RootNode
- GetRootNodeCore
- Initialize
- Clear
- BuildSiteMap

Web Forms :: Different CssClass For SiteMap.CurrentNode

Apr 8, 2010

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:


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.

Data Controls :: Populate DataList Based On QueryString Value Throws Error When QueryString Is NULL Or Blank

May 7, 2015

The following code works well as long as I pass a querystring value to the datalist.

Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"

[Code] ......

However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.

Most websites have pointed me to this code to use:

<asp:Label ID="lblEmpty" Text="No Result" runat="server"

The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

Dynamically Modify Role Permissions And Also Generate The Appropriate Sitemap / Menus?

Jun 28, 2010

I'm doing some research on security and sitemaps in ASP.net and am unfortunately running short on time. I have not worked too much with ASP.net security so I'm not completely sure if I'm heading in the right direction.

Here is my problem:

I have a public website (i.e. on the internet) that will allow any user to sign up to. The website will be developed using ASP.net webforms. These users may create other users and assign these users different roles.

Different roles have different restrictions and the menu is displayed appropriately. For example, a user acting as an administrator can see all menu options. Whereas a limited user will only see some of these menu items.

There needs to be the ability for users on our end to modify what pages certain roles can access. For example, if Role1 can do task X, we would like to be able at some point modify Role1 to no longer do task X. This would be done using an application built in-house.

User types (roles) are to be saved in the database. User permissions (what pages each type can have access to) are also to be saved saved in the database.

Here is something I am thinking of doing:

Implement the authorization and authentication set up built in to ASP.net using the web.config fileUse Sitemaps to dynamically create menus/breadcrumbs from the database

I believe it is possible to do the second one using custom providers (please correct me if I'm wrong). But I am not entirely sure if it's possible to configure the web.config file dynamically.

I suppose this is really more of a yes/no answer but I would just like to make sure I'm not going in the wrong direction. I will be using VS2008 and .net 3.5 framework.

Modify Request Querystring Parameters To Build A New Link Without Resorting To String Manipulation

Apr 6, 2010

I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:


would become:


And most importantly (perhaps) a request for:


would preserve the boring params to become:


Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring

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.

Web Forms :: How To Edit 'siteMapFile' Attribute Of SiteMap Provider In Web.config Dynamically

Dec 13, 2010

I want to add/edit available siteMap providers in web.config file from code behind.

I am using the siteMap providers currently in the application web.config in a format given below:

<add siteMapFile="~/App_Themes/MyAppDefault/MySiteMap.sitemap"
name="MyAppDefault" type="System.Web.XmlSiteMapProvider" />

This is allowing my application user to show up a different Site Map as and when the theme is changed.

But when I tried to do the same with the following code I faced with an issue.

configuration = WebConfigurationManager.OpenWebConfiguration("~")
section = CType(configuration.GetSection("system.web/siteMap"), SiteMapSection)
Dim provider As New ProviderSettings()
If Not section Is Nothing Then
provider.Name = txtError.Text
provider.Type = "System.Web.XmlSiteMapProvider"
End If

This code is not allowing a provider.siteMapFile property (provideer is the ProviderSettings object).
As well the maximum possible way I can add a new SiteMap provider in web.config is as follows

<add name="MyAppCustom" type="System.Web.XmlSiteMapProvider" />

If anybody can suggest a way for me to add/edit the 'siteMapFile' attribute of the provider.

How To Dynamically Modify Several Controls On A Page

Jan 5, 2010

I'm thinking there has to be an efficient and OO way to do this.

I have several textboxes on a data entry page. When I need to make a new entry, I have to clear the text field before making new entries and this has to be done for quite a number of textboxes and across several pages.

Is there a way to use the FindControl method to locate all textboxes on a page and clear their textfields probably using a loop of some sorts?
