Dear Team,
I have a rad tree view placed inside rad combo box. I need to retrieve the child node of the node inside the rad tree view dynamically. The rad tree view inside the rad combo box uses web services call for load on demand.
For example, if the tree node structure inside the rad combo box is as follows:
Node 1
Level 1
Level 2
Node 2
Level 1
Level 2
Initially, the combo box will display upon drop down Node 1 & Node 2. However, if we click Node 1 or Node 2, this will populate the child nodes.
My requirement is that I should be able to traverse from Node 1 through the deepest level via JavaScript API so that I can compare if this is the node or level that needs to remain selected on the rad combo box.
Kindly assist through me on achieving this.
Thanks in advance.

Hello,
An easy and convenient way of traversing all child nodes to a specific node would be to use RadTreeView node client-object method get_allNodes as shown in the code snippet below:

Dear Team,
Thank you for your reply.
We need further clarification.
if the variable 'node' refers to Node 1 that as two children Level 1 & Level 2, then there should be method to get these levels. Let us know how to achieve this.
Thanks in advance.

Hello,
I would like to clarify that
In other words if the clicked node is "Node 1" so

I would like to clarify that
get_allNodes()
will return all child nodes and their child nodes and so on for a specific node. This method traverses down the hierarchy of that node to the bottom where the node does not have child items. In contrast the method .get_nodes() will return only the direct child nodes of that specific node and will not traverse down the hierarchy. In other words if the clicked node is "Node 1" so
currentNode.get_allNodes()
will return level 1 and level 2 and their children and their children and so on if any. Regards,

Hi,
In the same question if i have another Node3 where i have only one level Level1
and now i want to display Level1 from Node3 & level2 from Node2 how to do that?
Actually in my project i am facing a problem when i clicke on Level1 of Node3 where it has only one child it is not displaying Level1 it displays Node3 which is parent node.While in Node1 & Node2 it's working fine because they have more then one child.
i hope i am clear to ask my doubt.
Thanks
