Hi TT,
1. The TreeViewAdv does have printing support, but currently there seems to be some issues in it. I have logged a bug report defect 565 in this regard, and we will try our very best to address this at the earliest. You could track the progress of this bug fix at this link below :
Defect #565 - Printing support in TreeViewAdv is broken
2. Could you please elaborate on your requirements with respect to undo/redo functionality in TreeViewAdv? If this is regarding node text editing, then please refer to the
test sample attached that illustrates this. Let me know if this helps.
Regards,
