I have a URL like so:
I am trying to see if there’s the existence of the anchor tag along with getting its value to do some code logic in the code behind.
I have been trying to use the Page.Request, but none of the properties show the anchor link portion of the URL.
I pretty much tried the combinations/properties on this page: http://www.west-wind.com/weblog/posts/269.aspx
Just to finalize this topic:
I copied Stack Overflow’s approach with a permalink… 😀

It’s not possible to retrieve the #anchor from the server side in ASP.NET.
This is a client-side flag to tell the browser to move to a specific place within the page.
var anchorValue; var url = document.location; var strippedUrl = url.toString().split("#"); if(strippedUrl.Length > 1) anchorvalue = strippedUrl;
Ref: Retrieving the anchor value from a URL
Being more explicit, the anchor tag is never sent as part of the HTTP request by any browser. It is only interpreted locally within the browser. Neither ASP.NET nor any other web server technology, Microsoft or otherwise will see the anchor on that request.
Section 2.4.1 –
“Note that the fragment identifier is not considered part of the URL.”
As others have suggested, the nearest you could get would be using client-side to read the browser window location.
A fragment can be parsed from a URL in C# in the following way:
var uri = new Uri("http://localhost?id=2#token=23"); var fragment = uri.Fragment; // Will return #token=23
There is a problem however in that the browser won’t send fragments to the server. If you receive requests from a service that includes this information in the request, it will be available from the server side too.
