I have been working from the article: How to: Configure Multiple Site Maps and Site-Map Providers (http://msdn2.microsoft.com/en-us/library/ms178426.aspx) I am not able to make it work. For simplicity of asking this question in a forum, I have created a basic website that contains a Web.config file and a Web.sitemap in the root folder. Also in the root folder are two folders: WebSite1 and WebSite2. When I try to run one of the sites I get the following error. Parser Error Message: The provider 'XmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection. I have pasted the pieces of code that are neccessary to look at below. Please help push me in the right direction.
Thanks,
Greg

Web.config

<

<?

/Website1/WebSite1.sitemap

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode provider="WebSite1SiteMap">
<siteMapNode url="Default.aspx" title="Default" description="Default of Site 1" />
<siteMapNode url="Default2.aspx" title="Default2" description="Default2 of Site 1" />
<siteMapNode url="Default3.aspx" title="Default3" description="Default3 of Site 1" />
</siteMapNode>
</siteMap>

Hi Greg,

1. The configuration listed in http://msdn2.microsoft.com/en-us/library/ms178426.aspx is not a full list of web.config file. You need to add the sample section into web.config file and modify it. Here is an example:

<?xml version="1.0"?>

<configuration>

        <appSettings/>

        <connectionStrings/>

        <system.web>

                <!--

            The <authentication> section enables configuration

            of the security authentication mode used by

            ASP.NET to identify an incoming user.

        -->

                <authentication mode="Windows" />

                <!--

            The <customErrors> section enables configuration

            of what to do if/when an unhandled error occurs

            during the execution of a request. Specifically,

            it enables developers to configure html error pages

            to be displayed in place of a error stack trace.

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">

            <error statusCode="403" redirect="NoAccess.htm" />

            <error statusCode="404" redirect="FileNotFound.htm" />

        </customErrors>

        -->

                <siteMap>

                        <providers>

                                <add name="WebSite1SiteMap"

                                        description="Default SiteMap provider."

                                        type="System.Web.XmlSiteMapProvider"

                                        siteMapFile="~/WebSite1/WebSite1.sitemap"

                                />

                                <add name="WebSite2SiteMap"

                                        description="Default SiteMap provider."

                                        type="System.Web.XmlSiteMapProvider"

                                        siteMapFile="~/WebSite2/WebSite2.sitemap"

                                />

                        </providers>

                </siteMap>

        </system.web>

</configuration>

2. According to the configuration, there should be two sitemap files.

/WebSite1/WebSite1.sitemap

/WebSite2/WebSite2.sitemap

However only one is provided, intead there is a Web.sitemap file.

<?

/Website1/WebSite1.sitemap

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode provider="WebSite1SiteMap">
<siteMapNode url="Default.aspx" title="Default" description="Default of Site 1" />
<siteMapNode url="Default2.aspx" title="Default2" description="Default2 of Site 1" />
<siteMapNode url="Default3.aspx" title="Default3" description="Default3 of Site 1" />
</siteMapNode>
</siteMap> 

If this file is not configured in web.config, it will be be used by ASP.NET at all. Please check this too.

Thank you for your reply I have made some changes, however I now get a error that states: WebDev.WebServer.exe has encountered a problem and needs to close. 

So now my website structure looks like this:

• SampleWebsite
• WebSite1 (folder)
• Default.aspx
• Default2.aspx
• Default3.aspx
• WebSite1.master
• WebSite1.sitemap
• WebSite2 (folder)
• Default.aspx
• Default2.aspx
• Default3.aspx
• WebSite2.master
• WebSite2.sitemap
• Web.config

 I copied and pasted your Web.config code so that should be fine. I deleted the web.sitemap in the root folder. I will paste the code for my WebSite1.master and my WebSite1.sitemap below. Please note that my WebSite2 content is exactly the same except for replaceing 1 with 2 where appropriate.

WebSite1.sitemap

Any Thoughts? Thanks, Greg

Hi,

The error usually means the ASP.NET Development Server crashes. I've found a similar thread:

http://forums.asp.net/thread/1600311.aspx

When Dev Server crashes it does not necessarily mean there is a bug in Dev Server. Your code might crash it too. So please check

Default.aspx

Default1.aspx

Default2.aspx

You can try to add a new page and select the WebSite1.master as the Master Page to verify if the new page crashes too. I think this can help narrow down the issue.

Zhao,

Thank you for your reply, sorry it has been so long for my response... didn't mean to be rude, just busy. I tried creating a new page under WebSite1.master and it crashes as well. Do you have any ideas, or do you know of a working example similar to what I am trying to achieve? Perhaps I could start with that code and modify to meet my needs.

 Thanks,
Greg

Greg,

I'll email a simple sample project to you.
