Hi Patryk,

Our developer couldn't reproduce, but try setting this flag to see if it helps:

Code
Select All
DevFlags.ResetRenderersAfterImageExport = true;


using new build here:

https://www.nuget.org/packages/MindFusion.Diagramming.Wpf/4.3.1-alpha2

Or let us know what we should change in attached project to see the problem.

Regards,
Slavcho

Hi Slavcho,

Setting the flag for true helps! Smiley

Although the change should also take into account the implementations of ContainerNode because here the template is still missing Wink

Looking forward to official release.
Best regards

Hi Patryk,

Do you mean ContainerNode's own template disappears after export, or container's child nodes? Does your application override ContainerNode.CreateRenderer too?

Best regards,

Yes, we have our own override CreateRenderer for ContainerNode. I noticed that our nodes did not loose the template but its not only for classes that inherits from ContainerNode Smiley

Sorry, I cannot parse that last sentence Sad Could you show before / after screenshots demonstrating what's hiding after export?

Re CreateRenderer, if caching the result as ControlNode's override you copied above does, check whether it works correctly if you return a new instance instead of caching (ControlNode has some code that moves Control between different views / WPF visual trees, but ContainerNode would not expect a shared renderer at all).
