BeforeRowColChange Event
The BeforeRowColChange event occurs when the user attempts to move to a different cell using the navigation keys or the mouse.
TDBGrid_BeforeRowColChange (Cancel As Integer)
Arguments
Cancel is an integer that may be set to True to prevent the user from changing the current cell.
This event fires regardless of whether the current cell is modified.
Setting the Cancel argument to True prevents the user from moving to a different cell. If you do not cancel this event, the behavior depends upon the modification status of the current cell. If the current cell is unmodified, then cell movement proceeds as usual and the RowColChange event fires. If the current cell is modified, then cell movement may be restricted by the BeforeColUpdate, BeforeUpdate, or BeforeInsert events, in which case the RowColChange event will not fire.
Note
The BeforeRowColChange event does not fire if the current cell is changed in code, such as by setting the Bookmark or Col properties of the grid.
