When DBGridEh is connected to DataSet of TMemTable type it allows:
To view all data without moving active record.
To display a tree-type structure of TMemTable records.
To form list of values in dropdown list of SubTitle filter automatically.
To create grouping records basing on the selected coulmns.
TDBVertGridEh component
Component to show one record from dataset in Vertical Orientation.
Have a special column to show Field Captions
Can customize inplace editor and data of the cell like in DBGridEh.
TDBLookupComboboxEh component
Provides all functionality of TDBLookupCombobox and adds
several new features as follows:
Can have flat style.
Allows assign values as to KeyValue property just and to
display Text property.
Allows to type (assign) values to Text property not contained in data list
(Style = csDropDownEh).

Take effect when KeyField, ListField, ListSource, DataField and DataSource
properties is empty.
Drop down list can:
Show titles,
Have sizing grip,
Automaticaly set width as sum of DisplayWidth of the list fields (Width = -1),
Automaticaly drops on user pressed the key.

Have specified width.
Have additional events: OnKeyValueChanged, OnButtonClick.
TDBSumList component
This component is intended for totaling sums and amounts of records in a
TDataSet with dynamic changes. Component keeps a list of TDBSum
objects, which contains types of group operations (goSum or goCount)
and name sum field (goCount name of field is unnecessary).
TPrintDBGridEh component
TPrintDBGridEh provides properties and routines for preview and
print of TDBGridEh component with several features:
Ability to expand rows vertically until all text is printed.
Ability to scale grid to fit it to page width.
Ability to print/preview title for grid.
Ability to print/preview page header and page footer where you can
specify macros for current page, current date, current time and/or static
text.
Automatically print/preview multiselected area of TDBGridEh if it area
is not empty.
Ability to print/preview rich text before and after grid.
TPreviewBox component
TPreviewBox lets you create a customizable runtime preview.
TPrinterPreview object
TPrinterPreview lets you to record printable data in buffer for following
output them on screen and to printer. TPrinterPreview have all functions and
properties as in TPrinter object. You can use TPrinterPreview object similarly
of TPrinter except some details. In TPrinter Printer.Canvas.Handle and
Printer.Handle is the same but in TPrinterPreview PrinterPreview.Canvas.Handle
represent the metafile in that is recored the data and PrinterPreview.Handle
represent Printer.Handle. That is mean that you have to use
PrinterPreview.Canvas.Handle for draw operation (DrawText, DrawTexteEx, e.t.c.)
and use PrinterPreview.Handle in functions that return information about
printer facilities (GetDeviceCaps, e.t.c.). Global function PrinterPreview
returns default PrinterPreview object and shows data in default preview form.
TDBEditEh component
represents a single or multi-line edit control that can display and edit a field
in a dataset or can works as non data-aware edit control.
TDBDateTimeEditEh component
represents a single-line date or time edit control that can display and edit

TPropStorageEh, TIniPropStorageManEh, TRegPropStorageManEh components
Components realize technology to store component properties to/from settings
storage such as ini files, registry etc.

Besides, it:
Supports a special interface, which allows DBGridEh component to view all
