	Any way to prevent the shape so that if its dragged way too over the edge, it falls back right at the end of the diagram bounds instead of being cut off like in the photo attached?

	This Code diagram.RestrictItemsToBounds= RestrictToBounds.InsideOnly; does nothing to prevent the behavior mentioned. What's it supposed to do anyway?

	Is there a way to prevent a shape drifting off the Bounds.Bottom of diagram?

	Apparently that property is used only in the Windows version. You could handle NodeModified to return the node to the diagram's bounding rect. E.g. if you detect that node.Bounds.Bottom > diagram.Bounds.Bottom, or corresponding comparison for Right, then you return the node to position diagram.Bounds.Bottom - node.Bounds.Height or diagram.Bounds.Right - node.Bounds.Width. I hope that helps, Stoyan

	Solved Heres how: In protected void diagramView_NodeModified(object sender, NodeEventArgs e) Code // adjust DIAGRAM HEIGHT as lanes are added / dropped to compact the diagram around lanes // refering diagram //Diagram diagramPB = diagramView.Diagram; // finding last stage ShapeNode lastShapeNode = diagramPB.FindNodeById("Stage " + extVarStages) as ShapeNode; // check if last shape node's bottom is greater than diagram height, // if so increase diagram height to last shape node's bottom if (lastShapeNode.Bounds.Bottom > diagramHeight) { diagramHeight = Convert.ToInt32(lastShapeNode.Bounds.Bottom); diagramPB.Bounds = new System.Drawing.RectangleF(0, 0, diagramWidth, diagramHeight); } // check if last shape node's bottom is lesser than diagram height, // if so decrease diagram height to last shape node's bottom if (lastShapeNode.Bounds.Bottom < diagramHeight) { diagramHeight = Convert.ToInt32(lastShapeNode.Bounds.Bottom); diagramPB.Bounds = new System.Drawing.RectangleF(0, 0, diagramWidth, diagramHeight); }
