In my custom page type, you can select an uploaded file. That's fine, but in my ascx transformation, i'm having a hard time getting the URL. The field is 'Process'.
Here's what i currently have.
<%# IfEmpty(Eval("Process"),"N/A","<a href=" + Eval("Process") +" target='blank' class='icon download'>Download</a>")%>
When rendered, the html is this:
<a href="214b6876-cb39-4a58-813f-19dcb7c788e4" target="blank" class="icon download">Download</a>
I'm missing something.
You can use either of the 2 methods below. Both have their downfalls though.
<a href="<%# GetFileUrl("Process", "Something") %>"Link here<a/> this will
Downfall with this is if there is no value in the "Process" field, it will return an invalid URL. So I tend to use something a little better (but not much)
<a href="/getattachment/<%# ValidationHelper.GetGuid(Eval("Process"), Guid.Empty) %>/<%# ValidationHelper.GetString(Eval("NodeAlias"), "download") %>">Item to download</a>
This will create a valid URL with some invalid properties to it. Meaning if there is no value in the Process field, it will return 00000000-0000-0000-0000-000000000000. If the NodeAlias field is empty, it will return "download". So again, not 100% fool-proof but it works well in most cases.
Update
Check out this link:

I think the piece you need in here is in the "CMS.File page type" section:
<a href="<%#GetDocumentUrl("FileField ", "kenticopicture")%>">This is the link to the picture</a>
