I am trying to access javascript document from ASP.net page code behind. How do I do same thing as below in c# code behind?
document.getElementById(id).src = "myurl.com"
Thank you for your help.

Add runat="server" and an ID to the element. You should then be able to access the src via the attributes collection.
<img src="http://www.google.com/img.png" id="imgGoogle" runat="server" />
Dim src as String = imgGoogle.Attributes("src")

What relevance your answer has to do with above question?

From what I could make out from the question, and I may be wrong, is that he wanted to be able to access the element via the code behind (or server side).

It looks right to me, he wanted to just get the
src URL from the element.

What i am trying to do is to create a ASP.NET that refreshes to certain list of URL in given interval period (Like sildeshow). One of approach that I am using is to use Iframe on the page and assgin a url to Document.elementById('myframe').src = url. But, I am looking for a way to do this in code behind, not from javascript.

If you want to do it server side, you will need to do post backs or partial postbacks which isn't efficient at all. What you could rather do is load all the images before hand, hide them and show only one at a time. That way there are no postbacks/async postbacks to call the next image.
srcurl of a random div/panel/etc, not get "access" to it (I'm not even sure what that would mean)
