Overview of DataWindow object properties – PB Docs 126

Overview of DataWindow object properties

DataWindow object properties apply to the DataWindow object
itself, not to the DataWindow control or DataStore that contains
it. There are several ways you can affect the values of DataWindow
object properties at runtime:

  • Use the general-purpose
    Describe and Modify methods to get and set property values.

  • Use methods that get and set specific properties.

  • Use methods that get and set specific properties.

  • For many properties, enter expressions in the painter
    that set properties conditionally at runtime.

  • You can use the SyntaxFromSQL method
    on a transaction object to generate DataWindow source code that
    sets some DataWindow properties. You can use the generated code
    in the Create method to create new DataWindows.

Summary tables in the first part of this chapter

The tables in “Controls in a DataWindow
and their properties”
list the properties for each control
within a DataWindow object, with short descriptions. There are also
tables for DataWindowSyntaxFromSql object keywords. After
the first table of DataWindow properties, the tables are alphabetical
by control and keyword name.

The tables include check mark columns that identify whether
you can use that property with Modify (M)
or DataWindowSyntaxFromSql (S). When
(exp) is included in the description, you can
specify a DataWindow expression as the value for that property.
A DataWindow expression lets you specify conditions for determining
the property value.

At runtime, you can use Describe or dot
notation to get the value of all properties listed in all tables.

Alphabetical reference list in the second part of
this chapter

The second half of this chapter is an alphabetical list of
properties with descriptions, syntax, and examples. When you find
a property you want to use in the first part, look up the property
in the alphabetical list to find the specific syntax you need to
use. In the tables that describe the property values, (exp) again
indicates that you can use a DataWindow expression for the value.

Accessing properties in different DataWindow
environments

The property reference has syntax for Describe and Modify and
for PowerBuilder dot notation.

In the DataWindow Web control for ActiveX, you must use Describe and Modify to
access property values.

Examples and quoted strings

The only examples given are PowerBuilder examples. However,
the arguments for Describe and Modify are
quoted strings that are generally valid in all environments. If
the strings include nested quotes, see “Nested strings and special
characters for DataWindow object properties”
for information on the appropriate
escape character in each environment.

For more information and examples of setting
properties, see:
