Retrieving anchor link in URL for ASP.NET

Question

I have a URL like so:

http://localhost/place/663828/bangkok-paradise-restaurant-toronto#r306040

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.

For example:

Response.Write(this.Page.Request.RawUrl.ToString()); 

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... :D

Answer 1

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.

You can use some JavaScript code in the body onLoad event to check for an anchor and send it back to the server using Ajax.

var anchorValue; var url = document.location; var strippedUrl = url.toString().split("#"); if(strippedUrl.Length > 1)     anchorvalue = strippedUrl[1];
