Trying to move the aspxtopdf control into my own user control combined with a button.
Getting the following error after I call render

Hi,
You should not do that. You can only have one ASPXToPDF control in your page. You can put ASPXToPDF in the outer page, but use "ASPXToPDF.Instance" to reference the only ASPXToPDF control in your user control code.
Thanks!

I only have one ASPXToPDF control on the page - just encapsulated within my own user control along with a button to elminate duplicate code on multiple pages (doing essentially the same work in before and after render)

So will the ASPXtoPDF control just not work in a user control at all - is that what you are telling me?

We do not know why it fails for you and it works fine at here. Can you try to isolate the problem into a test project and send the test project to us? We can take a look once we have that. Please let us know once you have the test project so that we can let you know where to send it. Thanks!

When I put it on a new 'blank' page it works fine - this would seem to indicate another control on my original test page is conflicting - would microsofts ajax tab container/ tab panel be at fault? Seems to me I have seen elswhere in the forums where ajax controls were to blame for similar errors to mine own. I will slowly add other controls to the page to see if I can track it down for sure.

Got a chance to dig into this again today for a bit - appears the asp webforms Chart control on the page appears to be the likely culprit, going to keep digging to see if I can understand why exactly.

As a temp work around I put the charts inside a panel and added the panel to HtmlToPDF.Options.Invisible elements
and got

Any thoughts on why that might be? Do I also need to fill in the visibleelements property or will it take everything else?
I am guessing my best bet now is start a new blank project and reproduce the charts issue and send the project to you? I haven't been able to figure out why when I move the aspxtopdf control to my own user control that the charts no longer render properly (would it have anything to do with my control being in a 'Controls' folder?)

Hi,
Yes. That would be the best way. We do not really know what to tell you unless we are able to see and debug into the issue. So please let us know when you have the test project ready so that we can tell you where to send it.
Thanks!

Unfortunately I have been unable to reproduce so far and I have implemented my user control on a couple of other pages in the same app without issue - I will keep trying to reproduce - there is something very specific about this one page that is failing that must be causing this
