The Server Behavior API 331

canApplyServerBehavior()

Availability

Dreamweaver UltraDev 1.

Description

Determines whether a behavior can be applied. Dreamweaver calls this function before the

Server Behaviors dialog box appears. If this function returns a

true value, the Server

Behaviors dialog box appears. If this function returns a

false value, the Server Behaviors

dialog box does not appear and the attempt to add a server behavior stops.

Arguments

serverBehavior

■ The serverBehavior JavaScript object represents the behavior; it is necessary to modify

an existing behavior. If this is a new behavior, the argument is

null.

Returns

Dreamweaver expects a Boolean value: true if the behavior can be applied; false otherwise.

copyServerBehavior()

Availability

Dreamweaver UltraDev 1.

Description

Implementing the copyServerBehavior() function is optional. Users can copy instances of

the specified server behavior. In the following example, this function is implemented for

recordsets. If a user selects a recordset in the Server Behaviors panel or the Data Binding

panel, using the Copy command copies the behavior to the Clipboard; using the Cut

command cuts the behavior to the Clipboard. For server behaviors that do not implement this

function, the Copy and Cut commands do nothing. For more information, see “How the

Server Behavior API functions are called” on page 326.

The

copyServerBehavior() function should rely only on behavior object properties that

can be converted into strings to exchange information with the

pasteServerBehavior()

function. The Clipboard stores only raw text, so

participant nodes in the document should

be resolved and the resulting raw text should be saved into a secondary property.

NOTE

The pasteServerBehavior() function must also be implemented to let the user paste the

behavior into any Dreamweaver document.
