Huge amount of data in TreeView

Hi,

A customer asks for visualising data in a tree. Generally data is well
structured and appropriate for being represented in a tree. The only problem
is the massive amount of data. I would like to avoid pre-loading data into
the tree, since it takes ages to do so. Instead, it would be nice if the
customer could click on a node and the respective child nodes will be
appended to that node.

Is there a components that realise this?

Thank you
Ralf

The standard MSFT treeview activex control has an Add method for the
Nodes collection.
This can also nicely be done with a webbrowser control and some DHTML.
Visual Studio .NET's treeview control has specific support for lazy
loading.

Hi Tom,

Yes, I'm aware of this control, but how to detect if a click on an item was
made. There is no event for that.

Thanks,
Ralf

Again, study that object a bit more. You will find the NodeClick
event.
