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).

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
a datetime field in a dataset or can works as non data-aware edit control.
TDBComboBoxEh component
represents a single or multi-line edit control that combines an edit box
with a scrollable list and can display and edit a field in a dataset or can
works as non data-aware combo edit control.
TDBNumberEditEh component
represents a single-line number edit control that can display and edit a numeric
field in a dataset or can works as non data-aware edit control.
TPropStorageEh, TIniPropStorageManEh, TRegPropStorageManEh components
Components realize technology to store component properties to/from settings
storage such as ini files, registry etc.
TMemTableEh component
dataset, which hold data in memory. Its possible consider as an array of
records.
Besides, it:
Supports a special interface, which allows DBGridEh component to view all
data without moving active record.
Allows fetch data from TDataDriverEh object (DataDriver property).
Allows unload change back in DataDriver, operative or postponed (in
dependencies of the CachedUpdates property).
Allows to create a master/detail relations on the client (filtering record)
or on the external source (updating parameters [Params] and requiring data
from DataDriver).
Allows once-only (without the dynamic support) sort data, including
Calculated and Lookup field.
Allows create and fill data in design-time and save data in dfm file of the
Form.
Allows keep record in the manner of trees. Each record can have record

温馨提示
解压后,有一个Installer文件夹,里面有EhLibInstaller.exe,双击后,选择你当前使用的DELPHI版本,然后点击nstall按钮,DELPHI7测试通过 安装结束后,可以在安装目录下面的X:\Borland\Delphi7\Components\EhLib查看适合你版本的文件 进入DELPHI在面板栏多出一个EhLib,说明安装成完成了。 补充说明: 1、WINDOWS7/WINDOWS8必须以管理员身份运行EhLibInstaller.exe 2、64位系统安装后启动DELPHI7,注意是DELPHI7这些低版本,报错“EHLIB70.bpl”丢失,解决方案:将EhLib路径添加到系统变量PATH路径中,注意用分号;和前面的其他程序的参数隔开
