goDiagram in web

I want to show my diagram in web pages and I want the diagram to be interactive, i.e. if user clicks on a node a database queries will be fired and some more nodes will come up.
I
understand this is possible when I am using goDiagram for VB.Net. But
if I want to do it in web pages is it possible? If yes, how?

I hope I am clear on my doubt.

Sure, that works in GoDiagram Web too. Try: http://216.122.145.116/GoDiagramWeb2.4.1Samples/TreeApp/WebF orm1.aspx This sample doesn't use an actual relational database, but it should be clear where you want to add that code: by replacing the OnDemandTreeAppNode.QueryChildren method.
