Check childnodes when checking parentnode in Treeview (ASP.NET 2.0)

[dolberg]

Hi,

I have a Treeview containing groups and groupmembers and I would like
to have the childnodes (groupmembers) checked when checking a parent
node (a group). This is no problem using the
TreeNodeCheckChanged-event. The problem is that a post-back is required
to fire the event, and checking a checkbox in the Treeview doesn't
cause a postback. Is there someway to force a postback or some other
way to fire an event when checking a checkbox.

TIA
