How to get parent id of treepanel selected node)

[ozlem]

Hi,

I've been spending hours to get parent id of currently selected node of a treepanel. I could find the parent in server side but, couldn't convert it to node type. I need an urgent reply... Here you can see my codes.

                                      if(#{tpPotentialAndTargetInfo}.getSelectionModel().hasSelection())
                                        {
                                            var nodeId = #{tpPotentialAndTargetInfo}.getSelectionModel().getSelection()[0].data.id;
                                         
                                            #{DirectMethods}.UpdatePotentialAndTarget(nodeId);
                                            
                                        }

[DirectMethod]
        public void UpdatePotentialAndTarget(string id)
        {
           var subCategory= tpPotentialAndTargetInfo.GetNodeById(id); // this code returns nodeproxy.
           var category = subCategory.ParentNode();
           var mainCategory = category.ParentNode();
           var puarId = mainCategory.ParentNode();
        }

Hi @ozlem,

Send a parent node's id as an additional parameter of a DirectMethod.

A NodeProxy does know nothing about its parent.

Thanks for your answer. I solved the problem. Here you can see my codes.

var subCategory=#{tpPotentialAndTargetInfo}.getSelectionModel().getSelection()[0];
var subCategorıId=subCategory.data.id;
var category=subCategory.parentNode;
var categoryId=category.data.id;

#{DirectMethods}.UpdatePotentialAndTarget(subCategoryId,categoryId);

Thank you for sharing a solution. It can help someone on the forums in the future.

But there is no way to find parent NodeID from code behind in event not related with treeview.

When use

Tree.SelectedNodes(0). there is no ParentID or Parent anything...

If use Tree.GetNodeById or Tree.SelectedNodes(0).ToProxyNode.ParentNode

you CAN go to Parent but you can not do anything with it because there in no way to read name/text/id/anything useful.

So either you have node without parent property or you have NodeProxy parent which is useless.
