Hi Michael,
Thank you for contacting Syncfusion support.
We understand that you have below requirements in TreeViewAdv
1)Need to display Context Menu to the items of the TreeViewAdv.
2)Need an event to perform some action when header of the TreeViewItemAdv is edited.
If so, we have prepared a simple sample with TreeViewAdv in which we have displayed Context Menu using the “Context Menu” property of the TreeViewItemAdv and there is an event named “AfterItemEdit” which has been called when item is edited. It can be downloaded from the below location.
Also, please refer the below documentation link for further reference.
Regards,
Keerthana J
