c# - How to set up a breadcrumb in an ASP.net page

Question

My folder hierarchy for the pages are (They are all in the same folder):

Site.Master
Default.aspx
find_provider.aspx
provider.aspx

I have a Web.sitemap page set up:

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="~/Default.aspx" title="Home"  description="Homepage">
        <siteMapNode url="~/find_provider.aspx" title="Provider" description="Search for provider">
            <siteMapNode url="~/provider.aspx" title="Profile" description="Shows each provider profile" />
        </siteMapNode>
    </siteMapNode>
</siteMap>

I am calling in my MasterPage:

<div id="navigation">
    <ul>
        <li><asp:HyperLink runat="server" ID="lnkHome" NavigateUrl="~/Default.aspx">Home</asp:HyperLink></li>

        <asp:Repeater runat="server" ID="menu" DataSourceID="SiteMapDataSource1">
            <ItemTemplate>
                <li>
                    <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Url") %>'><%# Eval("Title") %></asp:HyperLink>
                </li>
            </ItemTemplate>
        </asp:Repeater>
    </ul>

    <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />
</div>

So Default.aspx is my landing page. User can click on find_provider.aspx to search for a provider of their choice. For each provider search result, the user can click on PROFILE link to view information for each individual provider, which is the provider.aspx page.

So:

• If I am on the home page my breadcrumb should be: Home
• If I am on the find a provider page my breadcrumb should be: Home Provider
• If I am on the profile page my breadcrumb should be: Home Provider Profile

Instead, I see this on my page (no matter what page I am in):

Please help me modify the code so that breadcrumb is shown for each sitenode and subsitenode.

Sample of what I want to achieve:

HTML:

<div class="bcHolder brClear"> <!-- BC MAIN -->
    <div class="innerBreadCrumb"> <!-- INNER BC -->
        <ul id="breadcrumb">
            <li><a href="default.aspx" title="Home"><img src="theImages/homeIcon.gif" alt="Home" title="Home" class="home" /></a></li>
            <li id="bc_fp"><a href="find_provider.aspx" title="Find a Provider">Find a Provider</a></li>
            <!--<li>{ON THE CURRENT PAGE TEXT/URL</li>-->
        </ul>
    </div> <!-- INNER BC -->
</div> <!-- BC MAIN -->

Output:

In reference to your question here: How to use Bootstrap style of BreadCrumb with my ASP.NET menu?

The SiteMapPath acts as the <ul/> tag in the HTML rendering. So to use the method there, your structure would likely be something like this:

<div class="bcHolder brClear"> <!-- BC MAIN -->
    <div class="innerBreadCrumb"> <!-- INNER BC -->
        <asp:SiteMapPath ID="SiteMap1" 
        runat="server"
        PathSeparator=" / " 
        ParentLevelsDisplayed="1" 
        PathDirection="RootToCurrent"
        ShowToolTips="true">
        <CurrentNodeStyle CssClass="current-node"></CurrentNodeStyle>
        <NodeTemplate>
            <li><a href="default.aspx" title="Home"><img src="theImages/homeIcon.gif" alt="Home" title="Home" class="home" /></a></li>
            <li id="bc_fp"><a href="find_provider.aspx" title="Find a Provider">Find a Provider</a></li>
            <!--<li>{ON THE CURRENT PAGE TEXT/URL</li>-->
            </NodeTemplate>
        </asp:SiteMapPath>
    </div> <!-- INNER BC -->
</div> <!-- BC MAIN -->

And then add the javascript you need to resolve the hyperlink of CurrentNode.

Hope this helps.
