Hello,
I have a problem using C1FlexViewer in my application. No matter how i define my layout, the C1FlexViewer, more specifically, the area where the PDF document is shown, gets always rendered on top of every other control.
In the attached image, I have a simple popup that is defined at the end of my MainWindow. The flexviewer is embedded in my XAML before that popup, so usually the popup should get rendered on top, with the the flexviewer behind of it. But as you can see, it’s the exact opposite: the flexviewer is on top and my popup is behind of it.
I have already tried setting the Panel.ZIndex property of the flexviewer, but that does not seem to have any effect. I have also read setting the ZIndex property is not supported at all in this blog post https://www.grapecity.com/forums/wpf-edition/wpf-flexviewerpdfviewer-pr
How can I ensure, that the flexviewer does not get always rendered on top of every other ui element?
As our company currently investigates, whether the flexviewer suits our needs and we can buy it, we would need any answer on that as soon as possible. If that did not work at all, that would a KO criterion for us.
Kind regards,
Andreas
