Activating treeview navigation by CSOM?

Question

I was wondering if it would be possible to activate treeview navigation using CSOM? I know it can bedone using powershell (TreeViewEnabled), but that doesn't directly translate to CSOM - at least I can't get it to work.

You just need to set the TreeViewEnabled of the CSOM SP Web object.

Try with the below sample code:

// auth code and get web logic

clientContext.Web.TreeViewEnabled = true;
clientContext.Web.Update();
clientContext.ExecuteQuery();

Using JSOM:

SP.SOD.executeFunc('SP.js', 'SP.ClientContext', function(){

    var clientContext = new SP.ClientContext.get_current();
    var web = clientContext.get_web();

    web.set_treeViewEnabled(true);
    web.update()
    clientContext.load(web);
    clientContext.executeQueryAsync(function(){
        console.log("success");
    },function(){
        console.log("error");
    });

});

Using REST API:

var updateTreeView = JSON.stringify(
{  
    '__metadata': {   
         'type': 'SP.Web'   
    },
    'TreeViewEnabled': true
 }); 


$.ajax({
    url: "https://<your-site>/_api/web/",
    type: "POST",
    data: updateTreeView,
    headers: {  
         "accept": "application/json;odata=verbose",  
        "content-type": "application/json;odata=verbose",  
        "X-RequestDigest": $('#__REQUESTDIGEST').val(),    
        "X-HTTP-Method": "MERGE"  
    },  
    success: function (data) {
        console.log("success");
    },
    error: function (err) {
        console.log("error");
    }
});
