Hello Yefta,

You are absolutely correct - you can achieve this requirement using the following approach:

<telerik:RadTreeView ... OnClientNodeClicking="nodeClicking">

JavaScript:

function nodeClicking(sender, args) {
    // custom condition
    if (args.get_node().get_text() == "Music") {
        args.set_cancel(true);
    }
}

Hope this helps. Please give it a try and let me know if it works for you.
