copy node + children

[Thomas]

dear community,

 I'm facing the following issue right now:

 within my TreeView it should be possible, that every node and all its children can be copied within the same tree. Therefore I've setup a button which calls a function that tries to copy the node + its children.

The function looks like this:

function CopyTreeViewItems() {
        var treeview = $('#treeview').data('kendoTreeView');
        var selectedNode = treeview.select();

        var data = treeview.dataItem(selectedNode);

        var newData = {
            id: GenerateGuid(),
            Name: data.Name + "tmp"
        };

        treeview.insertAfter(newData, selectedNode);
        var parentItem = treeview.dataItem(treeview.findByText(newData.Name)); //<--- this part is returning 'undefined'

            if (data.hasChildren) {
                var children = data.children.data();

                for (var i = 0; i < children.length; i++) {
                    var add = { id: GenerateGuid(), Name: children[i].Name };
                    treeview.append(add, parentItem);
                }
            }
}

The parent node is copied without any problems. If there are children of a parent node I'm not able to append them to the corresponding new parent.

Any advices?

Kind regards

Tom

I ended up getting the uid from the dS of the newly created parent and assigning the children by tree.findByUid() like this:

function CopyTreeViewItems() {

        var treeview = $('#AdminPart_BaseLines_TreeView').data('kendoTreeView');
        var selectedNode = treeview.select();

        var data = treeview.dataItem(selectedNode);

        var newData = {
            id: GenerateGuid(),
            Name: data.Name + "tmp",
        };


        treeview.insertAfter(newData, selectedNode);
        var treeviewDS = treeview.dataSource.data();
        var uid;
        for (var i = 0; i < treeviewDS.length; i++) {
            if (treeviewDS[i].Name === newData.Name) {
                uid = treeviewDS[i].uid;
            }
        }
        var parentItem = treeview.findByUid(uid);

            if (data.hasChildren) {
                var children = data.children.data();

                var added = [];

                for (var i = 0; i < children.length; i++) {
                    added.push({ id: GenerateGuid(), Name: children[i].Name + "tmp" });
                }
                treeview.append(added, parentItem);
            }

}
