nodes

Hmmm... that should return that the <% is open. Can you email us your language definition and parser for this?

To find the first child, just use the indexer of the current OutliningNode and pass in a zero index. Alternatively if you are looking for a child node that contains a specific offset, you can use FindNode or FindNodeRecursive depending on what you need.

I'll prepare a sample for you. Funny enough, sometimes the nodes are open, sometimes not, depending on how I nest them.
isOpen does correspond with the graphical line marks. So if it reports isOpen=true, there indeed is an open line end.
Problem is that for some reason and in some situations, open nodes get closed by child nodes.

Take your editor sample and vb.net language definition and enter this:

#region

{

#endregion

"{" should be an open node but it isn't.
Why?

It looks like you're using C# syntax in a VB.NET language. So { isn't recognized in VB.NET.

When I pasted the above code in C#, it worked fine and { was marked open.

My fault, I meant c#.

When I paste this code in:
#region
{
}
#endregion

I get a plus sign in front of #region and {
I get two short horizontal lines in front of } and #endregion
All is fine.

When I delete "}", there is just ONE short horizontal line left. From my understanding, there should still be two, one of which is open-ended since the end of the "{"-outlining node is missing.

So "{" starts an outlining node that is ended with #endregion, and when I collapse "{", it also collapses #endregion.

How can it be that one outlining node without an end uses the surrounding outlinenode's end as its own missing end?
Also, isOpen is false and suggests the outlining node was complete when in reality it is incomplete.

If a node is open, it will use the end offset of the parent node as its end offset. So it is behaving as designed.

I see that IsOpen is true for the brace when I debug it. I think you're looking at the wrong node for that. Remember that there is a root outlining node so there's really three nodes in this situation.

OK, I'll try and re-check the isOpen property.
Thanks!
