In tree we shouldn't be able to select a node.How to disable select the tree nodes.
Check the selection demo. It shows how to clear selection. For example you can do that in the Change event of RadzenTree.
Not to clear selection. Can't we disable user to select nodes?
No. This isn't supported. Clearing the selection is what we can offer as a workaround.
I found a simple way to not disable, but hide the selection, by setting the hover and selection background-color to transparent.
<RadzenTree ...
Style="--rz-tree-node-hover-background-color: transparent; --rz-tree-node-selected-background-color: transparent;">
</RadzenTree>
