The DialogConditionType inherits all Properties of the ConditionType.

DialogState/Id when set to True indicates that the Dialog is active and waiting for a response. Recommended state names are described in Annex A.

Prompt is a dialog prompt to be shown to the user.

ResponseOptionSet specifies the desired set of responses as array of LocalizedText. The index in this array is used for the corresponding fields like DefaultResponse, LastResponse and SelectedOption in the Respond Method. The recommended localized names for the common options are described in Annex A.

Typical combinations of response options are

• OK
• OK, Cancel
• Yes, No, Cancel
• Abort, Retry, Ignore
• Retry, Cancel
• Yes, No

DefaultResponse identifies the response option that should be shown as default to the user. It is the index in the ResponseOptionSet array. If no response option is the default, the value of the Property is -1.

LastResponse contains the last response provided by a Client in the Respond Method. If no previous response exists, then the value of the Property is -1.

OkResponse provides the index of the OK option in the ResponseOptionSet array. This choice is the response that will allow the system to proceed with the operation described by the prompt. This allows a Client to identify the OK option if a special handling for this option is available. If no OK option is available, the value of this Property is -1.

CancelResponse provides the index of the response in the ResponseOptionSet array that will cause the Dialog to go into the inactive state without proceeding with the operation described by the prompt. This allows a Client to identify the Cancel option if a special handling for this option is available. If no Cancel option is available, the value of this Property is -1.
