Programmatically Hide/Show Nodes

Hello,

I am having trouble figuring out how to hide and show a ShapeNode/DiagramNode on the client side dynamically without redrawing the map. I tried setting the visible property to false, but this doesn't make the node invisible unless I redraw the map. I also tried using jQuery's hide method, but it doesn't seem to be able to locate the node in the DOM.

How can I accomplish show/hide without having to redraw the map?

Thanks.

Hi,

This works in my test -

Code
Select All
function testVisible()
{
	var diagram = Diagram.find("diagram");
	diagram.getNodes()[0].setVisible(false);
}


If not working for you, try also calling diagram.invalidate() or node.invalidate() to force redrawing.

Regards,

Hi,

The setVisible() method worked perfectly. I don't have to redraw the map. Thanks very much!
