Get Nodes Parent

[Craig Broadhead]

Does anybody know of a way to get the parent node of the node you currently have selected?

Hi Craig,

This could be achieved via jQuery. As a possible approach I can suggest the following:

• Get the currently selected node via the select method of the Kendo UI TreeView;
• Search for the closest group;
• Search for the closest item.

Like here:

var treeView = $("#treeview").data("kendoTreeView");
var selectedNode = treeView.select();
selectedNode.closest(".k-group").closest(".k-item");

I hope the suggested approach fits your requirements.

Hi Iliana,

That works fine in one case but I have a case where i'm doing an OnNodeSelect on the treeview.

var tv = $("#treeView").data("kendoTreeView");
tv.bind("select", function(e) {Filters.OnNodeSelect(e);});

    OnNodeSelect: function(Node){ 
        Filters.RunFilters(Node);
    },

In this case i'm having to pass the Node object that is given to me by the select into my RunFilters routine because treeView.select(); still reports the old selected node at this point. My problem occurs in this case because i get the error when doing Node.closest in RunFilters "Node.closest is not a function". Is there a better way for me to be handling the OnNodeSelect that would allow me to be able to use Node.closest in my RunFilters routine?

Hello Craig,

I believe the error is due to the fact that in the select event the selected node should be passed as e.node. Like here: 

//....
tv.bind("select", function(e) {Filters.OnNodeSelect(e.node);});
//....

Please test you project as apply this minor change and let me know if you still observe any problems.
