An event that allows you to create a custom message panel.

Parameters:

• sender: SurveyCreatorModel
  A Survey Creator instance that raised the event.
• options.question: Question
  A question for which the event is raised.
• options.messageText: string
  A notification message that you want to display. Assign a custom string value to this parameter.
• options.actionText: string
  A caption text for the action link. Assign a custom string value to this parameter.
• options.onClick: () => void
  A function that is called when users click the action link. Assign a custom function to this parameter.

A message panel is displayed within a question box on the design surface. It contains a text message and an optional action link. The following image illustrates a built-in message panel that appears when a question sources its choice options from another question or from a web service:

To create a custom message panel, handle the onCreateCustomMessagePanel event. This event is raised for questions whose isMessagePanelVisible property set to true. The following code shows how to enable this property based on a condition. This code implements a custom data source selector for select-based questions (Dropdown, Checkboxes, Radio Button Group). When a survey author selects any data source other than "Custom", the isMessagePanelVisible property becomes enabled, indicating that the onCreateCustomMessagePanel event must be raised. A function that handles this event specifies custom message and action link texts and onClick event handler:

import { Serializer } from "survey-core";
import { SurveyCreatorModel } from "survey-creator-core";

Serializer.addProperty("selectbase", {
  name: "choicesDataSource",
  displayName: "Data source",
  category: "choices",
  choices: [
    { text: "Country", value: "country" },
    { text: "Region", value: "region" },
    { text: "City", value: "city" },
    { text: "Custom", value: "custom" }
  ],
  onSetValue: function (obj: any, value: any) {
    // Set the custom property value 
    obj.setPropertyValue("choicesDataSource", value);
    // Display the message panel based on a condition
    obj.setPropertyValue("isMessagePanelVisible", value !== "custom");
  }
});

const creator = new SurveyCreatorModel({});

creator.onCreateCustomMessagePanel.add((_, options) => {
  options.messageText = "Choices for this question are loaded from a predefined data source. ";
  options.actionText = "Go to settings";
  // Focus the "Data source" editor within the Property Grid
  options.onClick = () => {
    creator.selectElement(options.question, "choicesDataSource");
  };
});

An event that allows you to integrate a machine translation service, such as Google Translate or Microsoft Translator, into Survey Creator.

Parameters:

• sender: SurveyCreatorModel
  A Survey Creator instance that raised the event.
• options.fromLocale: string
  A locale from which you want to translate strings. Contains a locale code ("en", "de", etc.).
• options.toLocale: string
  A locale to which you want to translate strings. Contains a locale code ("en", "de", etc.).
• options.strings: any
  Strings to translate.
• options.callback: (strings: any) => void
  A callback function that accepts translated strings. If the translation failed, pass an empty array or call this function without arguments.

Within the event handler, you need to pass translation strings and locale information to the translation service API. The service should return an array of translated strings that you need to pass to the options.callback function. The following code shows how to integrate the Microsoft Translator service into Survey Creator:

import { SurveyCreatorModel } from "survey-creator-core";
const creatorOptions = { ... };
const creator = new SurveyCreatorModel(creatorOptions);

const apiKey = "<your-microsoft-translator-api-key>";
const resourceRegion = "<your-azure-region>";
const endpoint = "https://api.cognitive.microsofttranslator.com/";
creator.onMachineTranslate.add((_, options) => {
  // Prepare strings for Microsoft Translator as an array of objects: [{ Text: "text to translate" }]
  const data = [];
  options.strings.forEach(str => { data.push({ Text: str }); });
  // Include required locales in the URL
  const params = "api-version=3.0&from=" + options.fromLocale + "&to=" + options.toLocale;
  const url = endpoint + "/translate?" + params;
  fetch(url, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "Ocp-Apim-Subscription-Key": apiKey,
      "Ocp-Apim-Subscription-Region": resourceRegion,
      "X-ClientTraceId": crypto.randomUUID()
    },
    body: JSON.stringify(data)
  }).then(response => response.json())
    .then(data => {
      // Convert data received from Microsoft Translator to a flat array
      const translatedStrings = [];
      for (let i = 0; i < data.length; i++) {
        translatedStrings.push(data[i].translations[0].text);
      }
      // Pass translated strings to Survey Creator
      options.callback(translatedStrings);

    }).catch(error => {
      // If translation was unsuccessful:
      options.callback();
      alert("Could not translate strings to the " + options.toLocale + " locale");
    });
});

Survey Creator does not include a machine translation service out of the box. Our component only provides a UI for calling the service API.
