Make node not selectable but expandable

[John]

Is it possible to make a RadTreeView node not selectable but so that you can still expand it?

[Nikolay Tsenkov]

Hi John,

You can handle the ClientNodeClicked event and set it to node.set_selected(false). This way, the node will be expandable on dblClick, but never selected.

One more question on this...

I have stopped items that I do not want to be selected by using node.set_selected(false) and that worked fine until I added a server-side OnNodeClick event. Now although the node is deselected it still continues to call the OnNodeClick event. How can I stop this event from hapenning?

Hello John,

Please try to set AutoPostBack to false for the nodes whose OnNodeClick event you do not need to fire.

Tree View Nodes do not appear to have a property called AutoPostBack, only the Tree View control itself. Am I missing something?

  - You can handle the ClientNodeClicking event and cancel the actual click - args.set_cancel(true). Also you will have to move the functionality from ClientNodeClicked event (since it will not fire after you cancel the click).

Why isnt there just a property of a RadTreeView, lets say NodesSelectable?

 In all threads about this in this forum, answers are formed like this: 

_Try_ this: client side scripting solution, as in: "bash your head with some workaround solutions".

Hi Anders,

Currently the RadTreeNode object does not expose public property defining whether a node can be selected or not. If you think that this feature would add considerable value to the functionality of our RadTreeView control, you con log a Feature request in our public Feedback portal.

That would be an ugly client side hack to compensate for lacking functionality.
