I have one container shape and inside that have multiple Nodes and their link.

I want to resize and set bounds to container Node base on all nodes / Links bounds.

How can I achieve this?

How can I draw the rectangle like Border to all nodes and links in the diagram.

Hi,

If that container will contain all diagram items, call diagram.GetContentBounds before creating it and set container.Bounds to the returned content rectangle.

I hope that helps,
Stoyan

Hi,

thanks for your reply,

I will try your suggestion

one question

see the attached image; Is it possible to get Highlighted points from the diagram? [Min and Max point of node / link utilized in the diagram; so that we draw rectangle based on that]

Thanks

Hi,

The DiagramItem.GetBounds() method returns a Rect that contains all control points for DiagramLinks or the node's bounding rectangle for DiagramNodes. You could loop over all items to collect min/max coordinates or call Rect.Union() to find the union of all items' rectangles returned by GetBounds(). You can get individual control points of links using their ControlPoints property.

I hope that helps,
Stoyan
