Hello,
I am wondering if it is possible to set a RadContextMenu for certain nodes when creating them programmatically.
For example, my tree will look something like this:
[MAIN NODE]
[Child1]
[Child2]
[MAIN NODE 2]
[Child1]
[Child2]
Would it be possible to have a RadContextMenu only for the parent node, and then a separate RadContextMenu for all the Child nodes?

Hello, Daica,
In order to restrict the context menu showing, it is appropriate to cancel the RadTreeView.ContextMenuOpening event considering the Node.Level in the TreeViewContextMenuOpeningEventArgs. This property indicates whether the node is a parent one or a sub node:
Additional information about the context menu in RadTreeView is available in the online documentation:
https://docs.telerik.com/devtools/winforms/controls/gridview/columns/column-types/gridviewcomboboxcolumn
https://docs.telerik.com/devtools/winforms/controls/treeview/context-menus/modifying-the-default-context-menu
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
