- [ViewChangedEventArgs.ClipRectangle Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-servervisualization/viewchangedeventargs/cliprectangle-property/llms-full.txt): Gets the rectangular area, in pixels, which is affected through the changes. The coordinates are relative to the top-left corner of the view's image, which is determined through the View.Location and View.Size properties.
- [ViewChangedEventArgs.ScrollDistance Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-servervisualization/viewchangedeventargs/scrolldistance-property/llms-full.txt): Gets the amount the document has been scrolled. The direction is determined through the ScrollOrientation property. When the distance is less than zero the document is scrolled down or to the right, otherwise the document is scrolled up or to the left.
- [ViewChangedEventArgs.ScrollOrientation Property](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-servervisualization/viewchangedeventargs/scrollorientation-property/llms-full.txt): Gets a value which determines whether the change is the result of scrolling, either through setting the view's location in the document or through autoscrolling initiated through the control when the input position leaves the visible part of the document.
