Description

MoveNextSelectable is a Boolean function used to move either or extend the selection in the grid control by a specified number of selectable columns and rows.

Relative indicates whether the column and row arguments are relative to the current Col and Row (or current cell), or represent an absolute cell address.

When Relative is set to True, DCol and DRow can have positive or negative values which indicate the direction in which the selection is moved or extended. A positive value in DCol indicates the selection moves to the right. A negative moves the selection to the left. A positive value in DRow moves the selection towards the bottom of the grid. A negative value moves the selection towards the top of the grid.

Applications do not normally call MoveNextSelectable; it is used in the implementation of methods like:

It is also called when a new value is assigned to the FixedCols or FixedRows property.
