Multiple controls with the same ID were found. Trace requires that controls have unique IDs.
Hi
I've added a .net usercontrol as a macro to an existing umbraco ( v
4.0.2.1 ) website. When an error occurs in the code rather than displaying the actual error it displays this one:
Multiple controls with the same ID 'ctl00$ctl00$ctl00$ContentPlaceHolderDefault$ctl14' were found. Trace requires that controls have unique IDs.
I can't find that control in the html and I'm not quite sure where to begin finding it as the site was built by someone else. Is this something that has an obvious cause, if not where do I start trying to debug it?
Hi, thanks for the suggestion. I tried debugging a different page (using &umbDebugShowTrace=true) that doesn't have my ascx on and it still comes up with the same problem. Is there any way I can get umbraco to give me a hint about what control it's talking about? I tried looking in view source and there's no sign of ContentPlaceHolderDefault. Here is the stack trace

I'm having the same issue. From what I can tell, the issue is due to a Macro being cached. I change the Cache Period on my Macro to 0, and the error goes away. I update it to 60, and voila....the error is back.
Ah, that makes sense as I don't get that problem if I leave the page for a while before refreshing. I've finished the project now but I'll try that next time. Thanks.
Hi, does anyone have a solution to this apart from not caching the macro?
I have an xslt macro(navigation) cached in the master page and i'm doing a postback in another macro(.net) and it's complaining about multiple controls.
I could just not cache it but that seems like a waste.
I need help please I'm getting the same error, when I refresh the node it goes away but 1/2 hour latter it happens again

The ID given is the one that .Net generates when it renders the control, I expect the control itself that has been duplicated is called something like
ContentPlaceHolderDefault. and will be in the ascx file somewhere. I'd start looking there.
If the control only appears once in the ascx, is it possible that the the macro being called more than once in the template?

I had a documenttype that had two properties with the same alias that caused this error message
