I’m using the latest pro tree version and have a few issues …



Q1) Why would the highlighting of nodes stop? I have a new tree and the highlighting works fine. When I load a tree with data the highlighting stops.



Q2) How can I save the tree to JSON and save the image information too (saving as XML you can use setSerializationLevel)? I’m creating my tree from JSON data and saving it back to JSON, because I cannot use any ActiveX objects. However, saving the tree to JSON doesn’t save the images. I have nodes of certain types which is represented by a new image I’ve created.



Thanks for your help.

Hello,


>> Why would the highlighting of nodes stop?


Please, check that dhtmlxtree.css css is included.


Also the issue can be caused by additional item styles which are set in the xml


>> How can I save the tree to JSON and save the image information too


By the default the additional information (images,userdata,etc.) isn’t serialized.


But you can enable this serialization by setSerializationLevel method:


tree.setSerializationLevel(false,true);
