Treeview Node Loses highlight when context menu opens

[Phill]

Here's what I'm doing to make the right context mnue show up based on
what node was cliked:

private void tvwMenu_MouseUp (object sender, MouseEventArgs e)
{
//Select Node When Right Clicked & Set Context Menu To Use
if( e.Button == MouseButtons.Ri ght )
{
TreeNode node = tvwMenu.GetNode At( new Point( e.X, e.Y ) );
if( node != null )
{
TreeNodeMenuTag tag = (TreeNodeMenuTa g)node.Tag;
tvwMenu.Selecte dNode = node;
tvwMenu.Context MenuStrip = (tag.isMenu) ? cmnuMenuNode :
cmnuProgramNode ;
}
}
}

It works, but unlike the Solution Explorer treeview in VS when you
right click on a node the node loses its highlight. I don't like this
cux it makes it less obvious which node you are operating on. Anyone
know how to fix this?

Thanks.

Try setting the treeview's "Hide Selection" property to false.

Re: Treeview Node Loses highlight when context menu opens

Thanks for the tip it does improve things having the highlight still
show when the context menu takes focus.

Still, you have to click like 2x in order to right click another node.
Once to cause the context menu to loose focus and again to get the
context menu to appear on the new node.

In VS's Exlorer or even Windows Explorer though you don't have to.
Just right clicking another node (eben if the context menu is already
up) works.

Any idea how to accomplish this?

Re: Treeview Node Loses highlight when context menu opens

In your mousedown or up event handler (where you're determining what node
was clicked on), you'll have to programmaticall y set the selection to that
node. If you're relying on the treeview's selected node property, you'll
have to abandon that and call the methods to get the node based on the mouse
position.

Hello Phill, I'm Willian from Brazil ...

You most change the mouse position for some context. You can use method
PointToClient of treeview object. This method return a point in client
context.
For example:

Point position = myTreeview.Poin tToClient(new Position(e.X, e.Y));
TreeNode node = myTreeview.GetN odeAt(position) ;

Try it!
