Dialog class

Creates a new instance of the Dialog class.

new Dialog(dialogId?: string)

Parameters

Gets a default end-of-turn result.

static EndOfTurn: DialogTurnResult

Property Value

Remarks

This result indicates that a dialog (or a logical step within a dialog) has completed processing for the current turn, is still active, and is waiting for more input.

Unique ID of the dialog. Sets the unique ID of the dialog.

string id

Property Value

The Id for the dialog.

Remarks

This will be automatically generated if not specified.

Gets the telemetry client for this dialog. Sets the telemetry client for this dialog.

BotTelemetryClient telemetryClient

Property Value

The BotTelemetryClient to use for logging.

When overridden in a derived class, starts the dialog.

function beginDialog(dc: DialogContext, options?: O): Promise<DialogTurnResult>

Parameters

Returns

Remarks

Derived dialogs must override this method.

The DialogContext calls this method when it creates a new DialogInstance for this dialog, pushes it onto the dialog stack, and starts the dialog.

A dialog that represents a single-turn conversation should await DialogContext.endDialog before exiting this method.

• DialogContext.beginDialog
• DialogContext.replaceDialog

When overridden in a derived class, continues the dialog.

function continueDialog(dc: DialogContext): Promise<DialogTurnResult>

Parameters

Returns

A promise resolving to the dialog turn result.

Remarks

Derived dialogs that support multiple-turn conversations should override this method. By default, this method signals that the dialog is complete and returns.

The DialogContext calls this method when it continues the dialog.

To signal to the dialog context that this dialog has completed, await DialogContext.endDialog before exiting this method.

• DialogContext.continueDialog

When overridden in a derived class, performs clean up for the dialog before it ends.

function endDialog(_context: TurnContext, _instance: DialogInstance, _reason: DialogReason): Promise<void>

Parameters

Returns

Remarks

Derived dialogs that need to perform logging or cleanup before ending should override this method. By default, this method has no effect.

The DialogContext calls this method when the current dialog is ending.

• DialogContext.endDialog
• DialogContext.replaceDialog

An encoded string used to aid in the detection of bot changes on re-deployment.

function getVersion(): string

Returns

Unique string which should only change when dialog has changed in a way that should restart the dialog.

Remarks

This defaults to returning the dialogs id but can be overridden to provide more precise change detection logic. Any dialog on the stack that has its version change will result in a versionChanged event will be raised. If this event is not handled by the bot, an error will be thrown resulting in the bots error handler logic being run.

Returning an empty string will disable version tracking for the component all together.

Called when an event has been raised, using DialogContext.emitEvent(), by either the current dialog or a dialog that the current dialog started.

function onDialogEvent(dc: DialogContext, e: DialogEvent): Promise<boolean>

Parameters

Returns

True if the event is handled by the current dialog and bubbling should stop.

When overridden in a derived class, reprompts the user for input.

function repromptDialog(_context: TurnContext, _instance: DialogInstance): Promise<void>

Parameters

Returns

Remarks

Derived dialogs that support validation and re-prompt logic should override this method. By default, this method has no effect.

The DialogContext calls this method when the current dialog should re-request input from the user. This method is implemented for prompt dialogs.

• DialogContext.repromptDialog
• Prompt

When overridden in a derived class, resumes the dialog after the dialog above it on the stack completes.

function resumeDialog(dc: DialogContext, reason: DialogReason, result?: any): Promise<DialogTurnResult>

Parameters

Returns

A promise resolving to the dialog turn result.

Remarks

Derived dialogs that support multiple-turn conversations should override this method. By default, this method signals that the dialog is complete and returns.

The DialogContext calls this method when it resumes the dialog. If the previous dialog on the stack returned a value, that value is in the result parameter.

To start a child dialog, use DialogContext.beginDialog or DialogContext.prompt; however, this dialog will not necessarily be the one that started the child dialog. To signal to the dialog context that this dialog has completed, await DialogContext.endDialog before exiting this method.

Parameters

Returns

Parameters

Returns
