Documentposition of Span

[JoRoSch]

Hi everybody,
how can I retrieve the documentposition of a certain Span (not the current where the caret is in). The background is: I need to move the caret to a specific Span when pushing the FastForward / FastRewind button of a microphone to easily dictat in a RadRichTextBox.

Here is what I have yet:

List<NamedPermissionRangeStart> allPermissionRangeStarts = Document.EnumerateChildrenOfType<NamedPermissionRangeStart>().SkipWhile(a => a.Type != "Text").ToList();
            NamedPermissionRangeStart cur = (NamedPermissionRangeStart)Document.CaretPosition.GetCurrentSpanBox().AssociatedSpan.PreviousSibling;

            for (int i = 0; i < allPermissionRangeStarts.Count; i++)
            {
                if (allPermissionRangeStarts[i].InternalKey == cur.InternalKey)
                {
                    Document.CaretPosition.MoveToPosition(((Span)allPermissionRangeStarts[i + 1].NextSibling).?????)
                    break;
                }
            }

I hoped to find something that gives me the DocumentPosition where the "???" are.
Is this approach the right one?

Thanks in advance
Jo

Hello JoRoSch,
You can use DocumentPosition.MoveToInline(...) methods to navigate document position to any Inline, including Span-s and NamedPermissionRangeStart-s.
