RadDiagramContainerShape without typical behaviours

[Dario Concilio]

Hi to all,

I need a RadDiagramContainerShape that has not use auto-sizing capabilities, I would afterthat I add several RectangleShapes into RadDiagramContainerShape, I can't move any RectangleShape outside to RadDiagramContainerShape .

How can I do this? .... Can I do this?

Hi Dario,

You can manually control your RadContainerShapes by overriding the CalculateShapeBounds function of your container. This will allow you to set the size of the container and prevent it from being changed based on the children added.

If you are using a layout with your diagram, you will also want to change the LayoutContainerChildren property to prevent the layout algorithm from changing the position of the container children.

Hello Dario ,

In addition to Shawn's answer I will propose a solution to prevent dragging shapes from their parent container. You can use the PreviewDrag event of RadDiagram:

private void diagram_PreviewDrag(object sender, DragRoutedEventArgs e)
       {
           foreach (RadDiagramShapeBase shape in e.Items.OfType<RadDiagramShapeBase>())
           {
               if (shape.ParentContainer != null)
               {
                   e.Handled = true;
                   return;
               }
           }
       }
