Hi,
Sometimes my node became invisible because it gets out of the view. How I can set so that my diagram will alsowas be shown in the view. Please help.

Hi,

You could call diagram.resizeToFitItems() after adding and arranging nodes to make diagram.Bounds large enough to contain them. If you enable Diagram.AutoResize, it should grow automatically to contain nodes drawn interactively by users.

I tried this but it is creating a very small rectangle in which only my one node is visible not whole diagram. and When I use Diagram.AutoResize() it is saying is not a function . What should I do please help.

It's a property you could set on server side, or otherwise call Diagram.setAutoResize on client side. If you need the diagram to only grow, you could check if diagram.getBounds() contains diagram.getContentBounds(), and if it doesn't do a union of the two rectangles and assign it back to Bounds.

like this -

Code
Select All
function growToFitItems(diagram)
{
	var margin = 10;
	var contentRect = diagram.getContentBounds();
	var diagRect = diagram.getBounds();
	if (contentRect.bottom() > diagRect.bottom() ||
		contentRect.right() > diagRect.right())
	{
		diagram.setBounds(
			diagRect.union(contentRect.inflate(margin)));
	}
}


Regards,
Slavcho

Thankyou its done, my height got increased but width by changing layout was again out of focus, so I set margin to 20 and it is fine now.
