are two distinct display modes: Grid
Basic display modes:
- This is the normal display mode in HTML "table" format.
The field names are displayed in the top header row and the field values
are displayed in the rows below the header.
In the situation where there are a small number of fields, you can
display more data without scrolling by using the multiple grid (grid+/grid-)
mode. In this format, the grid will
be "wrapped" to additional columns.
- This format displays only one record at a time with the field names displayed
in the left column, and the field contents displayed in the right column. This
format can be used to display a large number of fields with a minimum amount of
horizontal scrolling. Additionally,
a multiple column feature (Form+, Form-) allows columns to "wrap",
minimizing the amount of vertical space required.
This wrapping is very useful when a large number of fields are to be
When a table has a large number of fields (250 for example), it would be
impractical to display all 250 fields horizontally.
Using the Form mode (with column wrapping) can allow you to view all of
the fields simultaneously. However,
you are limited to viewing and navigating only one record at a time.
There is a more elegant method of display that solves this problem known
as “Dual” (and “Dual-horiz”) mode.
In Dual mode, you would display a small number of key fields in Grid mode
and display the rest of the row data one record at a time in Form mode.
You could then click on a row in the Grid to select your record, and then
see all of the row detail on the Form. The
only difference between Dual and Dual-horiz is that Dual mode displays the Form
below the Grid and Dual-horiz displays the Form to the right of the Grid.
this display mode, the Grid would be displayed with record numbers in the first
column. Clicking on one of the
record numbers toggles the display to Form mode and displays that record.
You can remain in this view mode and navigate through the records one at
a time with the Next / Prev buttons, or can click on the Grid button to toggle
back to Grid mode. When screen space is at a premium, and many fields are to be
displayed simultaneously, "Both" mode can provide the best of both
worlds. It allows the Grid mode for
record navigation, and Form mode for detailed viewing of each field.
be intermixed. FieldName is the
text name of a field, like “[First Name]”.
If the name has embedded space(s), it must be enclosed in brackets.
FieldNumber starts at “0” and corresponds to the default field
sequence. The following examples
show a few possibilities:
X.dbFilterFlds = "[Car Name], [Manufacturer], Year, Price, MPG"
X.dbFilterFlds = "0, [Manufacturer], Year, 3, MPG"
X.dbGridHideFlds = "0, 1, 2, 3,7"
a field name has been changed using the dbNameMap
you should use whatever the name of the field was, before it was redefined in
best results, avoid using field names with special characters in them.
For example, if you want a column name to contain a question mark (?),
such as "PromoItem?", just call it PromoItem in your database and use
the dbNameMap property to change the way it will appear on the display.
Special characters, especially the question mark, are confusing to the
system's ODBC SQL and UPDATE statements and unpredictable things may happen.
Sorting Field Columns (Ascending and Descending)
otherwise specified, the field names in the header will be hot linked (except
memo and OLE OBJ). This particular hot link means that when clicked the first
time, the column will be sorted in ascending
When clicked the second time consecutively, the sort
will be changed to descending
another field will repeat the procedure starting at ascending order.
are used to specify the database and display format. The general form is:
Mydb.Property = “string_value” or
numeric_value or boolean value
All property names and values are case insensitive.
Delimiters are used to separate various values in the ASP-db property statements. Due to the fact that a property can contain any characters, it is necessary to allow the user to customize them. For example -
Here, comma is used to separate the a,b,c and d values. If one of them is a SQL statement like SELECT Field1, Field2 from TABLE, then comma cannot be used to delimite them any more. We have to do something like -
dbProperty="(;|)a| b| SELECT Field1, Field2 from TABLE | d
may redefine or override the standard parameter delimiters used
within the various ASP-db properties. This
is accomplished within the property statement itself by specifying the
delimiters that you want to use right at the beginning.
Just put the delimiters inside parenthesis and then you may use those
delimiters in the rest of the statement. The
general form is:
= “(abc)parm1,parm2,parm3 ; parm1,parm2,parm3 ; parm1, parm2,
(abc) is present, then a is the major delimiter, in this case a semi-colon, b is
the minor delimiter, in this case a comma, and c is the micro delimiter, in this
case a slash. For example, say parm1 was a company name like “Jones, Inc.”.
You would need to be able to include a comma in the parameter meaning you
wouldn’t be able to use a comma for a delimiter anymore.
You should do this instead: X.dbProperty
= “ ( ; | / ) Ford | Nike | Jones, Inc. ; Cars | Shoes | Hats ” (Note: spaces are
inserted in this documentation for readablity purposes and should not be used in
The one property that needs the most attention is the dbMagicCell. The standard delimiters are (;,#|~/). If the values contains one of these characters, the the delimiter has to be changed like Format=[$###,###]. This property conflicts the "#" and "," delimiter. So if this format is used the delimiters should be changed to something like (;^%|~/).
three delimiters used by this property are major separator (between the groups
of four parameters), minor separator (between parameters), and micro separator
(within the fourth parameter)
seven delimiters used by this property are major separator (between the groups
of three parameters), minor separator (between parameters), left format
delimiter, right format delimiter, field contents encloser, compare operator
delimiter, and the delimiter separating multiple compares .
= “ ( ; , [ ] ^ | ~) Cash, align=center, <font color = red> format =
[currency] </font> ”
= “ ( ; , [ ] ^ | ~)
Photo,,<IMG SRC = ^Photo^> ”
three delimiters used by this property are major separator (follows the first
group of three parameters), minor separator (between parameters), and field
contents encloser. Example:
= “ ( ; , # ) 8,Pick a Product,Click to See Inventory; #ProductID# -->
two delimiters used by this property are major separator and minor separator.
This is especially useful if you need to include the UID and PASSWORD
parameter on the DSN specificaion. Example:
/ , ) 1 / DSN=pubs; UID=sa; PWD=bananas / Table3 / Dual-horiz /
4,Auto,Lightgreen / gif / std"
three delimiters used by this property are major separator, minor separator, and
a third (presently unused) delimiter.
