how to enable map the node objects using arrows on canvas
like following image
currently my canvas existing like this, and currently that feature not available for the canvas
<diag:Diagram x:Name="diagram" PreviewDragOver="OnPreviewDragOver" AllowDrop="True" RotateCursor="Hand" ShowGrid="True" NodeModifying="OnNodeModifiying" AutoResize="None" AllowInplaceEdit = "True" SerializeTag="siteMap_SerializeTag" DeserializeTag="siteMap_DeserializeTag"/>
<diag:NodeListView x:Name="NodeList"/>
beside I applied NodeListView rectangle item in codebehind with following syntaxes
NodeList.Items.Add(new ShapeNode { Shape = Shapes.Rectangle, EnabledHandles = AdjustmentHandles.All & ~AdjustmentHandles.ResizeHandles, Bounds = new Rect(0, 0, 60, 30), TextAlignment = TextAlignment.Center });
where should I apply that feature,
for a node or for the mind-fusion diagram ?
