EXTENDING DREAMWEAVER CS4

Data sources

Arguments

sourceName, bindingName

• The sourceName argument is the name of the top-level node to which the child node is associated.

• The bindingName argument is the name of the child node.

Returns

Dreamweaver expects a Boolean value: true if the function has handled the edit; false otherwise.

findDynamicSources()

Availability

Dreamweaver UltraDev 1.

Description

This function returns the top-level nodes from the data source tree that appears in the Dynamic Data or Dynamic Text

dialog box or in the Bindings panel. Each data source file has an implementation of the

findDynamicSources()

function. When Dreamweaver refreshes the tree, Dreamweaver reads through all the files in the DataSources folder

and calls the

findDynamicSources() function in each file.

Returns

Dreamweaver expects an array of JavaScript objects where each object can have as many as five properties, which are

described in the following list:

• The title property is the label string that appears to the right of the icon for each parent node. The title property

is always required.

• The imageFile property is the path of a file that contains the icon (a GIF image), which represents the parent node

in the tree control in the Dynamic Data or Dynamic Text dialog box or in the Bindings panel. This property is

required.

• The allowDelete property is optional. If this property is set to false, when the user clicks this node in the

Bindings panel, the Minus (-) button is disabled. If this property is set to

true, the Minus (-) button is enabled. If

the property is not defined, the default is

true.

• The dataSource property is the simple name of the file in which the findDynamicSources() function is defined.

For example, the

findDynamicSources() function in the Session.htm file, which is located in the

Configuration/DataSources/ASP_Js folder, sets the

dataSource property to session.htm. This property is

required.

• The name property is the name of the server behavior that is associated with the data source, if one exists. Some data

sources, such as recordsets, are associated with server behaviors. When you create a recordset and name it

rsAuthors, the name attribute must equal rsAuthors. The name property is always defined, but can be an empty

string (

"") if no server behavior is associated with the data source (such as a session variable).

Note: A JavaScript class that defines these properties exists in the DataSourceClass.js file, which is located in the

Configuration/Shared/Common/Scripts folder.
