Did you ever wish of having a grid that lets you display and edit data not
as rows and columns, but as records? A grid that would allow you to build
unique user interface solutions? We offer you a new approach to the data
grid interface. We offer you DbAltGrid components suite.
DbAltGrid is fully compatible with common DBGrid shipped with VCL. TDbAltGrid class is a
TCustomDBGrid descendant, as TDBGrid is. By converting to DbAltGrid, you
will not get any code conflict or loss in grid functionality.
DbAltGrid adds the following features to the common DBGrid:
- Multiple lines per record. Unlike DBGrid, which
displays each record in a single row, DbAltGrid allows a free-form
layout for each record in the dataset. You can customize layout not only
at design-time but also at runtime. This approach provides an extremely
efficient screen space use.
- Hierarchical columns structure. Now you can sort your
columns into logical categories, consolidate them and assign each column
to a shared parent column. You can imitate a tree-like column structure
that way. Such interface is similar to object and array field types in
the Oracle 8 database, but you can emulate this powerful technique with
any other database now.
- Enhanced column resizing and moving. It is possible
to resize and move any column both horizontally and vertically at
design-time as well as at runtime. DbAltGrid animates the column being moved
with position indicators for sharper look and feel.
- Row resizing. A end-user can adjust height of rows to
meet his/her specific needs. Furthermore, user can adjust height
of each line in row separately.
- Row height and column width can be fine tuned with a
mouse double-click. It is possible to change
column widths automatically proportionally to the client width of a grid.
- Images in column headers. DbAltGrid has now got an
Images property, which allows you to attach an ImageList to
display pictures in column headers.
- Clickable button-like depressible column headers.
Header arrows indicate the sorting column and the sorting order used as
well as sorting possibility for any column.
- Automatic word-wrap in data cells. Ellipsis indicates
when the text does not fit data cell or header. In that case you can see
the full text in a hint window.
- Fast, smooth and flicker free painting. Off-screen painting
even by custom drawing in OnDrawColumnCell event handler.
- Smart key mapping. Optional Enter to Tab key
automatic conversion. If you want, pressing the DownArrow key when the
current record is the last record in the dataset does not result in appending
a new empty record. It is made possible with a hot key use. In the
MultiSelect mode a user can control whether to select a row or a
- Alternate row coloring. Odd and even rows
can be filled with alternate background colors like in ledger books.
- Header cursor. Focus rectangle is drawn in the title
cell of the selected column.
- Supports object fields and other advanced features of
- You can save and load the grid properties to
and from a text file, a stream, a resource file/compiled resource, or the system
registry at design-time as well at runtime. So it is possible to transfer settings from
DBGrid to DbAltGrid and vice versa.
DbAltGrid offers a new approach to the problem of controlling data
displayed and edited in a grid. DbAltGrid uses separate template components
to define such a control. DbAltGrid comes with a standard template set for
the most common chores, including displaying and editing numeric,
Boolean, date, time, memo, RTF memo, and graphic fields. One of them allows
you to indicate a string in cell as a hyperlink. There is also
a unique template for displaying child columns summary as RTF text. It's fairly easy to
descend new templates from our base TdagTemplate class. This makes
DbAltGrid infinitely customizable with templates of your own design!
The template components that we designed for DbAltGrid follow our strict
policy of minimal resource usage. You need only one instance of
template component of an appropriate kind in your application, irrespective
of grids and fields number. When you do not need functionality of any
template component, you do not add extra footprint to your executable
DbAltGrid Suite version 1.2 is available for Borland Delphi 4, 5
and Borland C++ Builder 4, 5. Please visit
