Access IFrame in C#

Question

Im reworking a page that was done in javascript.  In one of the java scripts there is a call like this which sets the source of an IFrame:

parent.document.getElementById('iFrameAdminToolControl').src="whatever.ascx"

How would I access that same IFrame from c# code behind page?

Answer 1

make the IFrame runat="server" and you will be able to access it in the codebehind
