We have two views (graphical windows, i.e. plugins) that are synchronized. They both show the same data in a different manner.
One view displays the data in grid form, the ohter in tree form, which I just switched over from Microsoft WPF to IG XamDataTree.

When I click on a row in the grid-view, it sends a C# event to the tree-view to select the corresponding item.
The tree-view receives the event, finds the corresponding view-model item, and sets a bound property equal to this found item, effectively selecting the correct XamDataTreeNode.

However, the keyboard focus is not set to the tree-view although I was scrrolling in the grid-view!!

Our XamDataTree is a custom one, that I located in an IG forum. Here it is (with very slight mods):

//--------------------------------------------------------------------
public class RsCustomIgTreeView : XamDataTree
{
    private static XamDataTreeNodesCollection msNodes;

    public static readonly DependencyProperty SelectedItemsProperty = DependencyProperty.Register(
        "SelectedItem",
        typeof(object),
        typeof(RsCustomIgTreeView),
        new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.AffectsRender, OnPropertyChangedCallback));


    public static void OnPropertyChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        FindCorrespondingNode(msNodes, e.NewValue);
    }

    public RsCustomIgTreeView()
    {
        ActiveNodeChanged += OnActiveNodeChanged;
        msNodes = Nodes;

        AddHandler(PreviewGotKeyboardFocusEvent, (RoutedEventHandler)OnPreviewGotKeyboardFocusEvent, true);
    }

    private static void OnPreviewGotKeyboardFocusEvent(object sender, RoutedEventArgs e)
    {
        var treeView = sender as RsCustomIgTreeView;
        if (treeView == null) return;
        var viewModelBase = treeView.DataContext as ViewModelBase;
        if (viewModelBase == null) return;

        if (!viewModelBase.IsActive)
            e.Handled = true;
    }

    void OnActiveNodeChanged(object sender, ActiveNodeChangedEventArgs e)
    {
        if (e.NewActiveTreeNode != null)
        {
            SelectedItem = e.NewActiveTreeNode.Data;
        }
    }

    public object SelectedItem
    {
        get { return GetValue(SelectedItemsProperty); }
        set
        {
            SetValue(SelectedItemsProperty, value);
        }
    }

    private static void FindCorrespondingNode(XamDataTreeNodesCollection nodes, object value)
    {
        foreach (XamDataTreeNode node in nodes)
        {
            if (node.Data.Equals(value))
            {
                node.IsActive = true;
                node.IsSelected = true;
                return;
            }
            if (node.HasChildren)
            {
                FindCorrespondingNode(node.Nodes, value);
            }
        }
    }
}
//--------------------------------------------------------------------

--> The fix was the event-handler "OnPreviewGotKeyboardFocusEvent", see above. Why is this necessary? Do all IG components have this behavior?

Thanks,
