Image path and BringPathIntoView on Treeview

[Jonathan]

I am fairly new to WPF and have not mastered MVVm so I'm building my treeview manually like so:

private void BindTreeToZipCodes(RadTreeViewItem parentNode)
        {

            if (parentNode == null)
            {
                trvZipCodes.Items.Clear();

                List<State> _states = StateService.GetActive();

                foreach (State _state in _states)
                {
                    RadTreeViewItem node = new RadTreeViewItem() { Header = _state.StateDescription };
                    node.DefaultImageSrc = "Resources/folder.png";

                    node.Tag = "State";
                    if (_state.StateCode == _selectedDealer.StateCode)
                    {
                        node.IsExpanded = true;
                        node.IsSelected = true;
                        _selectedPath = _state.StateDescription;
                    }
                    else
                    {
                        node.IsExpanded = false;
                    }
                    trvZipCodes.Items.Add(node);

                    //call recursively to add zip parts
                    BindTreeToZipCodes(node);
                }
            }
            else //parent node is not null - what level is it
            {
                if (((string)parentNode.Tag) == "State")
                {
                    List<ZipCodePart> _zipParts = ZipCodePartService.GetForState(parentNode.Header.ToString().Substring(0, 2));
                    foreach (ZipCodePart _zipPart in _zipParts)
                    {
                        RadTreeViewItem node = new RadTreeViewItem() { Header = _zipPart.ZipPart };
                        node.Tag = "ZipPart";
                        parentNode.Items.Add(node);
                    }
                    if (parentNode.IsSelected == true)
                    {
                        _selectedPath += " | " + _zipParts[_zipParts.Count - 1].ZipPart;
                    }
                }
            }

        }

The image file for the state does not load despite it being in the relative path in the project.  Does it ned to be loaded in as a resource somehow rather than just specifying the relative path? 

Also what is the format of the path when bringing a TreeViewItem into view (auto scrolling) in a non-bound scenario like this, when there is more than one level involved?  I thought I saw somewhere to separate the levels items with a " | " but it doesn't seem to work.

as in:

BindTreeToZipCodes(null);

trvZipCodes.BringPathIntoView(_selectedPath);

Thanks,
Jonathan

Hi I added a '/' at the start of the image path name and that works fine but I'd stil like to know the format fo the path when bringing a TreeViewItem that is mutiple levels deep into view in a scrolling treeview

Thanks

Hello Jonathan,

Please take a look at the attached project which demonstrates bringing a path into view in a databound scenario. The approach is very similar in a non-databound scenario. The project has been created following the blog post bellow:

Give it a try and let me know if it helps.

Hi, 

Have you got a VB.NET version of the example for this please. 

Thanks
Tessa

Hello Tessa,

You can use a code converter to translate examples from C# to VB.NET. We have a two-way (C#, VB.NET) converter that you can use if you like.

For your convenience I prepared and attached a version of the project from the Kiril's reply in VB.NET.

I hope this helps.
