BeforeMoveSelection is an overridden method in TCustomDbGrid used to perform actions needed before the selected column in the grid is changed.
DCol and DRow contain the column and row number for the cell selection that will be selected following the selection change.
BeforeMoveSelection calls the inherited method on entry to signal the OnBeforeSelection event handler (when assigned). When DCol is different than the value in the Col property, the OnColExit event handler is signalled (when assigned). An internal flag is set to indicate that a column enter event is pending.
BeforeMoveSelection is called from the inherited MoveExtend method.
