Description

UpdateSelectionRange is a method used to update the Selection property with the cell coordinates for the current cell or row in the grid control. UpdateSelectionRange creates a new TRect instance with the cell coordinates representing the current selection in the grid.

UpdateSelectionRange uses values in Options to determine whether the rectangle represents a single cell or the current Row. When goRowSelect has been included in Options, the rectangle contains the non-fixed column and last column numbers in the current Row. Otherwise, the rectangle uses the value in Col and Row to represent both the start and end cells for the Selection.

UpdateSelectionRange is called from the ClearSelections and FixPosition methods.
