Or just type click here. The runat-command will make asp.net to resolve the url.

but that will make the link postback instead of being just a regular link.

I was looking into why an example code I was using also used the tilda. Normally I try to expelectily write out file/link paths and was pretty curious as to why they were using it for their user controls.

It turns out with .net server side controls when the app is compiled the tilda will be “translated” into a Request.ApplicationPath request from within the application project.

This is why it wouldn't work without the runat=”server”. Its because it only works on the server side and is translated correctly on compulation.

Hope this helps, someone else out if their trying to figure out why exactly this works :).
