ASP - Pick Images of Root Folder into Sub Folder

Question

I have had a look at this page

HTML - pick images of Root Folder from Sub-Folder

This page contains an example for HTML images. I have created a web control that represents footer of all the website pages. Now some pages are directly in the root and some are in another folder. In the web control I have to fix the

So without switching between ../ or ./ how can I determine the root of the website and then say something like root/images/abcd.jpg in the web control?

This ~/ don't work at all neither in the main page (directly on the root) nor in the page inside a folder :( — Azhar Khorasany, Aug 28 '12 at 14:02
@AzharKhorasany If Oded's suggestion doesn't work for you is because you need to make the `img` tag a server control by adding `runat="server"`. I explained this on my answer. — Icarus, Aug 28 '12 at 14:17

If you make your <img> tag a server control by adding runat="server" you can simply do the following and it will always resolve the url correctly, regardless of where the user controls is referenced:

<img id="image" src='<%=ResolveClientUrl("~/images/abc.jpg")' />

The ResolveClientUrl method will automatically resolve the correct path starting off from the root of the app (~/)

var url = HttpContext.Current.Request.Url;
return url.AbsoluteUri.Replace(url.AbsolutePath, "") + "/";

To get the root.

Its an tag. How will this code work in an html img tag? – Azhar Khorasany Aug 28 '12 at 14:03
if it's asp.net, can't you generate the path serverside? – Attila Szasz Aug 28 '12 at 14:04
I can, but I can't access the img id on the .aspx.cs file? The only other way is to use an ImageControl rather than . Is that what you are asking me to do? – Azhar Khorasany Aug 28 '12 at 14:07
runat="server" for the img to access it's ID server side. But then if you want client side access, use TheID.ClientID – Attila Szasz Aug 28 '12 at 14:08
