TreeLayout and IgnoreContainers

[Max]

Hello. I tried to apply tree layout on 50 generated nodes (by first tab).

This is result:

But, while IgnoreContainers=true, result is:

Why  layouting don't work in this case? I don't want to involve containers in layouting algotithm.

The screenshots are from your demo projects (xaml-sdk-master).

Hello Max,

Thank you for bringing this issue to our attention. Indeed, it's a bug in our RadDiagram and we logged it in our feedback portal where you can track its progress. We updated your telerik account points as thanks for your cooperation. 

As a temporary workaround, you can save the containers positions in a dictionary and re-set them after Layout:

Dictionary<RadDiagramContainerShape, Point> ContainerPositions = new Dictionary<RadDiagramContainerShape, Point>();

private void RadButton_Click(object sender, RoutedEventArgs e)
      {
          TreeLayoutSettings sett = new TreeLayoutSettings()
          {
              TreeLayoutType = TreeLayoutType.TreeDown,
              IgnoreContainers = false,
          };
          sett.Roots.Add(this.diagram.Shapes[0]);


         this.diagram.Shapes.OfType<RadDiagramContainerShape>().ForEach(x => ContainerPositions.Add(x, x.Position));
         this.diagram.DiagramLayoutComplete += (oo, ee) =>
          {
              this.diagram.Shapes.OfType<RadDiagramContainerShape>().ForEach(x => x.Position = ContainerPositions[x]);
          };
         this.diagram.Layout(LayoutType.Tree, sett);

      }
