- =========================================
- Part 1 - What Are Data Widgets?
- =========================================
-
- Data Widgets is a set of bound custom controls that
- allow you to design front ends for database
- applications with all the ease and power you have come
- to expect with Visual Basic. Data Widgets virtually
- eliminates the need for time-consuming coding when
- developing database applications. All you need to do
- is drop a control on a form, set a few properties, and
- Data Widgets will do the rest!
-
- =========================================
- Part 2 - Control Feature Lists
- =========================================
- Data Widgets includes 6 bound custom controls. The
- controls in the set are:
-
- DataGrid -----------------------------------------------
- The DataGrid is a fully editable, bound grid
- that allows you to edit an entire record set, no
- matter the size, on screen with no code whatsoever.
-
- The following is a list of the features:
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * Breaks the 64K barrier
-
- * Loads only enough records into memory to fill
- display area
-
- * Supports in-place editing
-
- * Supports multi-colored cells and/or rows
-
- * You can specify fixed columns and optionally
- allow the user to change this with a splitter bar
-
- * Can be used as bound list box (single column
- grid)
-
- * Functionally and visually consistent with the
- Microsoft Access grid
-
- * Automatically provides add, update and delete
- functionality with no coding
-
- * Supports drop down lists (DataDropDowns) by
- column which can be optionally linked to
- other data controls
-
- * Provides an optional cell button for triggering
- specialized processing for a column
-
- * Variable properties for each column such as
- alignment, format mask, etc.
-
- * Optional column headings and row labels
-
- * Column headings will default to field names
- but can be overridden
-
- * Supports 2-D or 3-D appearance
-
- * Supports unbound columns for displaying calculated
- fields
-
- DataCombo -----------------------------------------------
- The DataCombo is a bound combo box you can include
- in your database application.
-
- The following is a list of the features:
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * Breaks the 64K barrier
-
- * Edit and drop down portions can be linked
- to separate data controls
-
- * Loads only enough records into memory to
- fill display area
-
- * Variable properties for each column such
- as alignment, format mask, etc.
-
- * Optional column headings
-
- * Column headings will default to field names
- but can be overridden
-
- * Supports 2-D or 3-D appearance
-
- * Supports unbound columns for displaying
- calculated fields
-
- DataDropDown --------------------------------------------
- The DataDropDown is a custom control that you can
- use to attach to a cell in the DataGrid to drop
- down a list of values from another source of data.
-
- The following is a list of the features:
-
- * Used in conjunction with the DataGrid
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * Breaks the 64K barrier
-
- * Loads only enough records into memory to
- fill display area
-
- * Variable properties for each column such as
- alignment, format mask, etc.
-

-
- DataOption Button ---------------------------------------
- The DataOption button is a 3-D option button that
- you can link to a field in a database and have it
- turn "on" when a certain value is in that field,
- also toggling the others that may be in a group of
- DataOptions to "off".
-
- The following is a list of the features:
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * 3-D appearance
-
- * Each option button in a group represents
- a different value for the same DataField
-
- * Set one option button's DataSource or
- DataField and the other option buttons in the
- group will synchronize themselves
- automatically
-
- DataCommand Button ---------------------------------------
- The DataCommand button is a custom control that
- binds to a data control and automatically performs
- a database action when pressed.
-
- The following is a list of the features:
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * Just like our standard 3-D Command button
- but can also be linked to a Data Control and
- automatically provide positioning functions
- for moving to the beginning or the end or
- forward or backward in the Data Control's
- Record Set one or more records
-
- Enhanced Data Controls -----------------------------------
- The Enhanced Data Controls are custom controls that
- behave as a front end to the Visual Basic data
- control adding new functionality.
-
- The following is a list of the features:
-
- * Bound to the new data control in Visual
- Basic 3.0
-
- * Binds to a data control on a different form
-
- * In addition to the previous, next, first
- and last button of the standard data control
- this control provides 2 additional buttons
- that will allow the user to go forward or
- backward multiple records in the Record Set
- for each click (the # of records forward or
- backward can be set via properties)
-
- * The buttons have been enhanced to keep
- moving forward or backward in the Record Set
- while the buttons are held down. A delay
- between the single and multiple moves can be
- specified.
-
- * Can have either a vertical or a horizontal
