Re: TreeView: right-click

Check that...

Put two controls on a form.  One being a tree view - add some nodes.  The
other being something else like a listbox.  IN the mousedown event for the
treeview, set the SelectedNode using treeview1.SelectedNode =
treeview1.GetNodeAt(e.X, e.Y).  Run the app.  Right click on the list box.
Right click on the treeview but in an empty area of the treeview.  Note that
although the SelectedNode is null, the first item in the tree is
highlighted.  Any way to stop this?

Thanks, Patrick.  Works like a charm.

Patrick,

First, it must be in the mousedown event.  What is available for finding the
clicked node in this event?  Nothing else has happened to the tree yet when
this event fires.  I do have access to the x, y, and location variables form
the MouseEventArgs argument.  How do you find the clicked node from these?

In the MouseDown (or maybe MouseUp) event, if the right-mouse was clicked,
set the SelectedNode property to the Node that was clicked on.

Subject: [DOTNET-WINFORMS] TreeView: right-click


And since it's late and my brain isn't working well right now, one more...

I have a TreeView control on a form with a bunch of nodes displayed.  If I
'left-click', the treeview highlight shows on the item I clicked.
However, if I 'right-click', it doesn't.  How do I change the TreeView's
behavior so that the 'right-click' moves the highlight just like the
'left-click' does (the same behavior that happends in Windows Explorer),
please?

Peter
