Scroll event not firing

Hi Marc,

I don't believe SyntaxEditor ever raised the inherited Scroll event.  In the newer codebase, if you have two SyntaxEditors to keep in sync, you'd first want to disable view splitting by setting SyntaxEditor.CanSplitHorizontally to false.  Then attach to the SyntaxEditor.ActiveView.TextAreaLayout event.  That will fire whenever changes to the view occur, such as changes that can affect scrolling.  The view's ScrollState property gives the current scroll state.  If you wish to sync up the other editor, you can use the SyntaxEditor.ActiveView.Scroller.ScrollTo() method.

This TextAreaLayout event approach works well enough for our purposes. To allow independant horizontal scrolling I used the following code:

var otherView = e.View == editorOld.ActiveView ? editorNew.ActiveView : editorOld.ActiveView;
var scrollState = new TextViewScrollState(new TextPosition(e.View.ScrollState.VerticalAnchorTextPosition.Line, 0), e.View.ScrollState.VerticalAnchorPlacement, e.View.ScrollState.VerticalAmountOffset, otherView.ScrollState.HorizontalAmount);
scrollState.CanScrollPastDocumentEnd = true;
