I am binding the parent nodes to a treeview initially and intends to bind the children of each node on LoadOnDemand.I am checking whether each parent node is having child nodes on initial bind to show or hide the expand-collapse button.I want to hide the expand-collapse button for those nodes who doesn't have any child.
Help me.
Thnx in advance.

Hello, Ranjitha,
By default, when a parent node has child nodes it shows the expand-collapsed buttons. If it has not any child nodes, then this button is not shown. This behavior is normal and would come out of the box. Can you please share more information about the case that you have. Is your RadTreeView bound or not?
If you are facing difficulties, it would be very helpful if you can provide a simplified project and demonstrate there the problem that you are having. Thus, I could be able to investigate it further.
Looking forward to your reply.
I am glad to hear that you have solved your issue.
Generally speaking, you can turn off the LazyMode property to support this scenario:
treeView.LazyMode = false;Do not hesitate to contact us if you have further questions or issues.

Thanks Julian, this worked for me.
I had a weird situation recently on an old app. Although in our development environment the tree view nodes looked fine, when deployed, the expand icon started appearing on all the tree nodes once one of them had been clicked, regardless of whether they had children or not?
After applying the setting above and doing a new build, they went away.
