Hi,

In the "Completion Filtering" example, the unmatched items in the completion list will be filtered out until it shows "(no items)". Is it possible to set the list to Auto-Hide when there is no items in the list?

I tired to set the following properties, but it's not work.

Dim session As New CompletionSession()
session.CanHighlightMatchedText = True
session.CanCommitWithoutPopup = True
session.CanFilterUnmatchedItems = True

Thanks,
Cow

Sorry there isn't an option for that right now.

Is it possible to put it into the enhancement list?

Yes we can add it, although in some scenarios it may not make sense to use an option like that. For instance if you are using other filters like the buttons/tabs, the list shouldn't hide in scenarios where those sorts of UI are active in the list.

It's just an additional options to enrich the product. You have the right to choose not to use it.

It's very annoying to keep popping up with no items while the user it's typing. In VS2010, the completion list will disappear automatically when there is no items in the list. It's more user-friendly.

Thanks.

I'm looking for some clarification to the above.

My case is the following: I'm displaying the CompletionSession as a suggestion of the possible items that the user might want to type (i.e. not the complete list of everything that's valid). For example, I might have "1abc" in the completion list but at the point where I pop up the list, just typing the number '1' might also be valid (or any number that starts with a 1). So while I want to display the auto-complete list when the user starts typing a valid item, I NEED the auto-complete list to go away once I can determine that what is typed is valid but not in the list. So in a SelectionChanged event handler on the completion session I can determine if what the user typed is valid or not and then I'd like to say something like

if (session.IsOpen && session.Selection == null)
{
session.Cancel();
// or
session.Close(true);
}

but both of those cause crashes.

Is there something I call on the SyntaxEditor (or any other way) to tell the completion session to just go away?

Hi Andy,

You should be able to call session.Cancel() without it crashing. Maybe send us a simple sample project that shows the crash so that we can debug it and fix the problem as appropriate. Thanks!
