Can you have 2 url's that point to the same page in an asp:Menu control?

Question

I have an asp:Menu and it contains a top level menu item that points to http://www.example.com/one.aspx. When you hover over the top level menu item, it shows a dropdown and one of the selections is One which points to http://www.example.com/one.aspx. Apparently, I can't do this, so I have been putting a ? at the end of the second url to get around this. I was curious as to if it is possible to have two of urls pointing to the same location in an asp:Menu?

Answer 1

I had the same problem and used a slight variation of your solution: I added anchors to the URL, e.g:

• http://www.example.com/one.aspx#1
• http://www.example.com/one.aspx#2

BTW: I was using a sitemap file, and when you add to nodes with the same URL to that file, then the error/exception is pretty clear:

Multiple nodes with the same URL '/WebSite1/MyPage.aspx' were found. XmlSiteMapProvider requires that sitemap nodes have unique URLs.

So I guess it really is not possible to have to identical URLs.

Answer 2

I don't believe so.

The Menu control uses each item's NavigateUrl property as the identifier for highlighting and expanding the menu correctly - if you have two nodes with the same URL, how will the control know which one to highlight?

I found out my solution in the comment above only worked on Firefox, this is an improved solution to make the page refresh even if you click on the same link as the current one but with an hash tag:

$(document).ready(function () { // refresh page when clicking menu item with current address $('#<%=aspMenu.ClientID%> a').click(function () {
   var currentUrl = location.pathname;
                var clickedUrl = $(this).attr('href');
                if (currentUrl.indexOf('#') != -1 || clickedUrl.indexOf('#') != -1){
                    if (currentUrl.indexOf('#') != -1)
                        currentUrl = currentUrl.substring(0, currentUrl.indexOf('#'));
                    if (clickedUrl.indexOf('#') != -1)
                        clickedUrl = clickedUrl.substring(0, clickedUrl.indexOf('#'));
                    if (currentUrl == clickedUrl)
                        location.reload();
 }); });

Or even better: removing the anchors with the digits from the hrefs on document ready:

    $(document).ready(function () {
        $('#<%=aspMenu.ClientID%> a').each(function () {
            var re = /#\d/
            var url = $(this).attr('href');
            $(this).attr('href', url.replace(re, ""));
        });
    });

You can attach a query string variable that changes e.g.

<siteMapNode url="~/UnderConstruction.aspx?x=1" title="Customer"  description="Customer" />
<siteMapNode url="~/UnderConstruction.aspx?x=2" title="User"  description="User" />
<siteMapNode url="~/UnderConstruction.aspx?x=3" title="Area"  description="Area" />
<siteMapNode url="~/UnderConstruction.aspx?x=4" title="Well"  description="Well" />
<siteMapNode url="~/UnderConstruction.aspx?x=5" title="Build Report"  description="Build" />
