Programmatically usage

I'm trying to build diagram programmatically. I created project like explained in Getting Started section of documentation. Then I write something like:

ShapeNode node = DiagramLite.CreateShapeNode(100, 100, 100, 100);

DiagramLite.Nodes.Add(node);

and run the project but can't see added nodes.

What am I doing wrong?

Not sure, but you should either use the Factory method without calling Nodes.Add:

ShapeNode node = diag.Factory.CreateShapeNode(100, 100, 100, 100);

or use a constructor to create the node and call Nodes.Add:

ShapeNode node = new ShapeNode(100, 100, 100, 100);
diag.Nodes.Add(node);

Also make sure the diagram.Bounds rectangle is large enough to show the nodes at the coordinates you specify.

I hope that helps,
Stoyan

Thanks, it worked. Another question: Who do I enable from code zoom functionality declared in component feature list?

There is the ZoomFactor property, specifying zoom level in percents. You could change it from menu item, button or mouse-wheel event handler.

I hope that helps,

You can also look at the Discussion topic:
"zoom method , how? "

This has example to use that and more insight provided earlier by Stoyan

Does it mean that zoom is available on server-side only?

Why it should mean that? Just add a menu item or button to your Silverlight page and handle them on the client side by changing Diagram.ZoomFactor.
