Set editable range by handling event

Many before-event provided by ReoGrid have the property IsCancelled, which can be set as true to notify Control to cancel the following operations. It typically to be used to prevent the cell-edit or outline-collapse/expand operations.

For example, to only allow the text editing inside specified range:
var editableRange = new ReoGridRange(3,1,2,3);

grid.SetRangeBorder(editableRange, ReoGridBorderPos.Outline, ReoGridBorderStyle.SolidBlack);

grid[2, 1] = "Edit only be allowed in this range:";
grid.BeforeCellEdit += (s, e) => e.IsCancelled = !editableRange.Contains(e.Cell.GetPos());
