Event when scrolling vertically

Hi Daniel,

The IEditorView.TextAreaLayout event fires any time a layout occurs, which could be due to scrolling, editor resizing, zooming, or just changes in the document that require a repaint. You should be able to listen to that event to keep your side-by-side views in sync.

You can find details about the available data exposed by the event here:

Please let us know if you are unable to achieve what you need based on that event.

Hi,

That event is what I need.

Also, is there a way to set the FirstVisiblePosition? If I scroll on the left editor and I know which is the FirstVisiblePosition, I also want to set that somehow on the right editor.

Kind regards,

Daniel

Hi,

I have a solution but this is not behaving like I would want because I need the caret to stay where it is when scrolling.

Now I am setting the CaretPosition and then I scroll the line to visible top.

ActiveView.Selection.CaretPosition = new TextPosition(firstVisibleLine, 0);

ActiveView.Scroller.ScrollLineToVisibleTop();

Kind regards,

Daniel

Hi Daniel,

The editor.ActiveView.ScrollState property returns a TextViewScrollState object that has all the information about how the view's scroll state is anchored and positioned.

You can call editor.ActiveView.Scroller.ScrollTo(scrollState) to set a TextViewScrollState on another view.

The Scrolling documentation topic covers these APIs if you want to reference that.
