Scroll Event

Hi Mike,

You can watch the editor.ActiveView.TextAreaLayout event to know when a layout occurs.  It can happen for more than just vertical scrolling (i.e. resizing, etc.), and will cover all cases.  But since many things can trigger a layout (even multiple things at the same time sometimes), there isn't an indicator of what originally triggered it.

But there isn't a way to block scrolling.  And remember scrolling can happen simply by moving the caret, which occurs from many edit actions.  

Can you describe more about your scenario and why you are wanting to block scrolling?

Hi,

the document is dynamically built (lines get appended/added on scroll). Its basically an endless document and therefore I need an endless scroll behavior. As of now we are using a slider + attached to the Scrollviewer.scroll event which exists on most controls but on Syntax Editor this event does not fire.

I've already guessed it would be much more complicated if Syntax Editor does not have such an event as like you said, there are plenty of things to take care of. I don't know how SyntaxEditor internally works but do you think you can add this event in next release? Maybe just expose the internal scroll event?

Hi Mike,

Couldn't you watch the ActiveView.TextAreaLayout event I mentioned?  If you see it reaching a certain point (you can watch editor.VisibleViewLines' last line's position to know how far it's scrolled), then add more text to the document.
