Call Grid.Datasource.DisableInterface/EnableInterface in the BeforeScroll
and AfterScroll events, respectively, of the dataset.

IBO Help for DisableInterface:
<<
Similar to DisableControls but calling this only disables user interface
controls.
Applies to
TIB_DataSource
Declaration
procedure DisableInterface;
Description
Master-Detail and Lookup links will continue to operate. NB. Isolates user
interface controls by checking for datalinks that have been derived from
TIB_ControlDataLink.

Be sure to use a "try...finally" block to guarantee that every call to
DisableInterface has a corresponding call to EnableInterface.

IB_Grid can give you a popup window of the memo text if you use its
EditLinksAuto property (& you have the option of defining your own edit
display instead of the default popup).
