WMVScroll is a method used to handle a LM_VScroll message for the control. It ensures that the dataset for control is repositioned for the window message. No actions are performed in the method if the DataLink for the control is not active.
WMVScroll checks the ScrollCode member in Message to determine the actions performed in the method. The following scroll code values are handled:
Other scroll code values in Message are ignored.
WMVScroll calls ScrollBarPosition to update the position for the vertical scroll bar on the control. If EditorMode is enabled, the private RestoreEditor method is called to toggle the value in EditorMode and redraw the editor control.
