An editing-style method for changing BackgroundProperties.
procedure SetBackgroundPropertyEd(Prop: TRVBackgroundPropertyId;
Value: Integer; AutoReformat: Boolean);
(introduced in version 24)
Parameters:
Prop identifies a property of BackgroundProperties.
Prop – new value for this property.
If AutoReformat=True, Change is called. Normally, this method is called with AutoReformat=True if you change a single property. If you call this method together with other methods in a group, this parameter must be False, and you must call Change yourself.
Method type: 
editing-style (unlike direct assignment to sub-properties of BackgroundProperties).
Example:
if MyRichViewEdit.CanChange then
begin
MyRichViewEdit.BeginUndoGroup(rvutBackground);
MyRichViewEdit.SetUndoGroupMode(True);
MyRichViewEdit.SetBackgroundPropertyEd(rvbpidVisible, Ord(True),
False);
MyRichViewEdit.SetBackgroundImageEd(Image1.Picture.Graphic, False);
MyRichViewEdit.SetUndoGroupMode(False);
MyRichViewEdit.Invalidate;
MyRichViewEdit.Change;
end;
