Expanding node in web application

We have drawn a treechart in web application using webchart.net.dll. We want to expand and collapse the nodes of tree.

fc.BoxesExpandable = true;
fc.RecursiveExpand = true;
fc.ExpandButtonPosition = ExpandButtonPosition.OuterTop;

Expand button appears on the boxes, but nothing happens when we click it.

Try setting the HtmlBuilder.ExpandBtnHyperLink property to a page on your server which should process the expand/collapse action. You can get the index or tag of the box which should be expanded by adding {0} or {1} format specifiers to the hyperlink. Then on the server check the box identifier, expand or collapse the affected tree branch and redirect to the diagram page.

Is it compulsory to use hyperlink in the box? Is there other way to expand/collapse the nodes without using hyperlink?

The webchart library can only generate images on the server side, and it is not a full blown web control (yet), so there is no other way to handle the expand/collapse except setting that hyperlink and handling it on the server side.
