Hello,

I think it is not because our WebTreeView, but closely to iframe issue. Since you are not using our control in loading IFrame, then something must be wrong with the code that load iframe content. If you seen my sample, I used WebPaneManager. It can load iframe content correctly in there.
So, I don't think if this is an issue in our WebTreeView, since your load iframe code is not came from us.
