Treeview automatically selects node when expanding? 1

[theweirdo]

Hi there,

I noticed that TreeView in windows forms seems to automatically select the treenode when the user clicks the plus/minus sign beside it to expand the tree.

I'm having a problem with this because I want something to happen after a treenode has been explicitly selected, not automatically selected when expanding. Is there a way to differentiate between an implicit select and an explicit select?

Thanks.

I don't see that.
When a TreeView is shown there is no selection on any items until the TreeView control receives the focus using the mouse or TAB & arrows keys or the focus is set on this control by application.
If a node has the focus e.g. is already selected and it is expanded then the focus remains on that node until a item is selected using the mouse or down arrow. That item will get selected.
