Hello,
Is there a posibity to attach a new node to an existing treeview without recursive walking throught the tree.
I have a unique id fo each row.
For example i nedd to and a new item to Chilfd nodes collection of node with id 99
Can i do this without recursive walking the tree?
Thanks

Hi Lukasz,

Thanks for contacting Syncfusion Support.

We have analyzed your query and we are prepared a sample as per your requirement.  In this sample, we have a unique ID for each parent node and you can add a new item to child node collection by searching the ID parent node using GridTreeControl.InternalGrid.Nodes collection. It is not possible to find the parent node without any recursive methods or loops.

Please refer the below code sample

C#

private void Button_Click(object sender, RoutedEventArgs e)

        {           

            var viewModel = this.treeGrid.DataContext as ViewModel;

                var node = new PersonInfo() { Id = 0, LastName = "Buchanan", FirstName = "Pradap", Designation = "Employee", DOB = new DateTime() };

            

                foreach (var item in this.treeGrid.InternalGrid.Nodes)

                {

                if (item.ParentNode == null)

                {                   

                    if ((item.Item as PersonInfo).Id == node.Id)

                        {

                            // Node added

                            item.ChildNodes.Add(new GridTreeNode(item.Level+1, node, false, item));

                        }

                   }                   

                }

                treeGrid.InternalGrid.ReloadNodes();           
        }
