Hi Rajesh,

You can set explicit text position by overriding ShapeNode.UpdateVisuals and setting the TextMargin property to the value you need after calling the base method.

If you set TextMargin directly without overriding UpdateVisuals, the control will change it automatically to match the Shape.TextRectangle value once you move or resize the node, but you might try updating it from a NodeModifying handler.

To show a border, modify the ShapeNode's Xaml template and insert a <Border> element between the Grid and TextBlock elements.

You could show a temporary node when the user enables text-repositioning mode, and synchronize the text position with the node's position while the node is being moved.

I hope that helps,
Stoyan
