ObjectBrowser to WpfTreeView conversion.

DenisFRDenisFR FRANCE ✭✭✭
Hello,
I want to make an addin which makes a new ProjectBrowser with filter ability.
Here the Code:
            //Get ObjectBrowser Window
            Window objectBrowserWin = UIEnvironment.Windows["ObjectBrowser"];
            //Get Control normally as ABBInternal.ProjectBrowser.LayoutBrowser;
            var layoutBrowser = objectBrowserWin.Control;
            if ( !(layoutBrowser is null) && layoutBrowser.IsHandleCreated)
            {
                // Get first Control (Second is tool buttons)
                System.Windows.Forms.Integration.ElementHost elementHost = (System.Windows.Forms.Integration.ElementHost)layoutBrowser.Controls[0];
                WpfTreeView wpfTreeView = (WpfTreeView)elementHost.Child;
                // Get TreeModel normally as ABBInternal.ProjectBrowser.LayoutTreeModel
                TreeModel treeModel = wpfTreeView.TreeModel;
                if (!(treeModel is null))
                {
                    //Create new window
                    ToolWindow toolWindow = new ToolWindow("FilteredObjectBrowserWindow")
                    {
                        Caption = "Filtered ObjectBrowser."
                    };
                    UIEnvironment.Windows.AddDocked(toolWindow, System.Windows.Forms.DockStyle.Top, UIEnvironment.Windows["ObjectBrowser"] as ToolWindow);

                    WpfTreeView filterTreeView = new WpfTreeView();
                    // Create a copy treeModel
                    WpfTreeModel wpfTreeModel = new WpfTreeModel();
                    filterTreeView.TreeModel = wpfTreeModel;
                    wpfTreeModel.ExpandRootNodes = treeModel.ExpandRootNodes;
                    wpfTreeModel.ExpandedNodes.AddRange(treeModel.ExpandedNodes);

                    // Create the ElementHost control for hosting the
                    // WPF UserControl.
                    System.Windows.Forms.Integration.ElementHost host = new System.Windows.Forms.Integration.ElementHost
                    {
                        Dock = System.Windows.Forms.DockStyle.Fill,

                        // Assign the WPF UserControl to the ElementHost control's
                        // Child property.
                        Child = filterTreeView
                    };

                    // Add the ElementHost control to the form's
                    // collection of child controls.
                    toolWindow.Control.Controls.Add(host);
                }
            }
But this crash RS directly when I put mouse hover a node with that error:
System.InvalidCastException
  HResult=0x80004002

How can I make what I want?
