With support's help, I am able to set up the tree so that it displays data in something other than a strictly hierarchical fashion. This requires that I handle the tree's GetChildren event.

A read of the documentation makes it clear that I can handle sorting programmtically as well. What is not so clear is whether or not I must handle sorting programmatically, when the GetChildren event is handled. My experimentation seems to suggest that the answer is yes.

So, to be clear: If I so much as stub out the GetChildren event handler, is the ITypedList-provided sorting permanently disabled? Or, is it supposed to work, provided that the developer get the tricky business of programmatic databinding working just so?

Thanks once again.

If you are handling the GetChildren event then you will also need to handle the sorting. This means your GetChildren handler will need to check the current SortColumn of the tree and sort the collection returned by the GetChildren event accordingly.
