Advanced Card View Functionality

This tutorial builds off the following tutorial: Build your first SharePoint Adaptive Card Extension

In this tutorial, you'll implement advanced card view functionality. You'll build off the the previous tutorial and create a card view that's powered by data in a SharePoint list.

Create a test list

Prepare this tutorial by creating a new list in a SharePoint site with some sample data:

  1. Browse to your site and create a new list named Instruction List.

  2. Add a Single line of text column named Description.

    Empty SharePoint list

  3. Add a few items to the list:

    • Title: Step 1, Description: Use ACEs
    • Title: Step 2, Description: ???
    • Title: Step 3, Description: SPFx 🚀 🌝
  4. Get the list's ID:

    1. While viewing the list, select the gear icon in the suite bar to open the Settings menu. Then select the List settings menu item:

      List settings screen

    2. On the List Settings page, locate the list's ID in the URL:

      List ID in the URL

    3. Save the list's ID so you can use it in the next step.

Add ACE functionality

Start with the HelloWorld ACE from the previous tutorial, Build your first SharePoint Adaptive Card Extension. Make the following updates in preparation for Step 2.

Change properties

Let's modify the properties for our ACE and set the list ID that contains the data our ACE will display:

  1. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldAdaptiveCardExtension.ts.

  2. Update the interface used to define the type of the ACE's properties property:

    export interface IHelloWorldAdaptiveCardExtensionProps {
      title: string;
      description: string;
      iconProperty: string;
      listId: string;
  3. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldAdaptiveCardExtension.manifest.json.

  4. Initialize the ACE with the ID of the List created in the previous step by setting the following preConfiguredEntries:

      "preconfiguredEntries": [{
        // ...
        "properties": {
          "title": "HelloWorld",
          "description": "HelloWorld description",
          "iconProperty": "", // Default to sharepointlogo
          "listId": "" // TODO: enter list id


    Make sure you enter the ID of the list you previously obtained into the listId property in the preconfiguredEntries code above.

  5. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldPropertyPane.ts.

  6. Update the Property Pane by adding the following field:

    PropertyPaneTextField('listId', {
      label: 'List ID'

Change the ACE's state

Next, let's update the state of the ACE. When the state changes, it will trigger the ACE to rerender. These changes will add a collection of list items to the state as well as the current item displayed, as indicated by the currentIndex property you'll add.

  1. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldAdaptiveCardExtension.ts.

  2. Add a new interface for the List data by adding the following code to the file:

    export interface IListItem {
      title: string;
      description: string;
  3. Update the interface used to define the ACE's state to use the new IListItem interface:

    export interface IHelloWorldAdaptiveCardExtensionState {
      currentIndex: number;
      items: IListItem[];
  4. Update the state initialization by updating the onInit() method in the ACE:

    public onInit(): Promise<void> {
      this.state = {
        currentIndex: 0,
        items: []
      // ...
  5. Temporarily remove where the state is referenced in the ACE and Views by updating the onPropertyPaneFieldChanged() method:

    // tslint:disable-next-line: no-any
    protected onPropertyPaneFieldChanged(propertyPath: string, oldValue: any, newValue: any): void {
  6. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/quickView/QuickView.ts.

  7. Update the data() and onAction() methods to the following:

    public get data(): IQuickViewData {
      return {
        subTitle: '',
        title: strings.Title
    public onAction(action: IActionArguments): void {

Now that the state has been updated, we can now update our ACE to fetch data from the SharePoint list.

Add dependency

The next step is to add support to the project and ACE to retrieve items from a SharePoint list. To do this, you'll use the SharePoint Framework (SPFx) API to call the SharePoint REST endpoint.

First, add a dependency to the SPFx package used to submit HTTP requests to REST endpoints:

  1. Locate and open the following file in the project: ./package.json. Take note of the beta version of the SPFx related beta packages used by the other packages listed as dependencies in the dependencies section of the package.json file.

  2. Install the following NPM package in your project: @microsoft/sp-http:

    npm install @microsoft/sp-http -SE

Fetch the list data

Next, add support for calling the SharePoint REST API and adding the retrieved items to the ACE's state. When the state is updated, it will trigger the ACE to rerender.

  1. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldAdaptiveCardExtension.ts.

  2. Request the list data using the SPFx SPHttpClient API. Add the following to the class that implements the ACE:

    import { SPHttpClient } from '@microsoft/sp-http';
    private _fetchData(): Promise<void> {
      if ( {
        return this.context.spHttpClient.get(
          `${this.context.pageContext.web.absoluteUrl}` +
          .then((response) => response.json())
          .then((jsonResponse) =>
            (item) => { return { title: item.Title, description: item.Description }; })
          .then((items) => this.setState({ items }));
      return Promise.resolve();
  3. Update the ACE to request the list data during when it's initialized by updating the onInit() method.

    Replace the last line return Promise.resolve(); to be return this._fetchData(); as follows:

    public onInit(): Promise<void> {
      // ...
      return this._fetchData();
  4. Update the ACE to request the list data when the Property Pane is updated. Add the following method to the class that implements the ACE. This code will only request the data when the list's ID is changed in the Property Pane:

    protected onPropertyPaneFieldChanged(propertyPath: string, oldValue: any, newValue: any): void {
      if (propertyPath === 'listId' && newValue !== oldValue) {
        if (newValue) {
        } else {
          this.setState({ items: [] });

Card updates

With the ACE updated to fetch items from a SharePoint list, let's update the card to display this data.

  1. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/cardView/CardView.ts.

  2. Update the data() getter to display data from the list:

    public get data(): IPrimaryTextCardParameters {
      const { title, description } = this.state.items[this.state.currentIndex];
      return {
        primaryText: title

Now you can test the ACE. Build and launch the ACE in the hosted workbench:

gulp serve

Once the local webserver has loaded, navigate to the hosted workbench: https://{tenant}


Remove any old instance of the ACE from your workbench. ACE instances from the previous tutorial will show an error message since the ACE properties have been updated.

Open the Toolbox and select your ACE:

Select the ACE from the Toolbox

Conditional card views

By default, Views are automatically responsive to the Card size. However, ACEs can optionally provide different Views for any given Card size.

Change the HelloWorld ACE to display the total count of List items in the Medium Card size, and display the List items in the Large Card size to maximize the use of available space.

Medium card view

Let's create a medium card view for our ACE:

  1. Create a new file ./src/adaptiveCardExtensions/helloWorld/cardView/MediumCardView.ts folder.

  2. Add the following code to create a new Medium sized card view:

    import {
    } from '@microsoft/sp-adaptive-card-extension-base';
    import {
    } from '../HelloWorldAdaptiveCardExtension';
    // Extend from BaseBasicCardView
    export class MediumCardView extends BaseBasicCardView<IHelloWorldAdaptiveCardExtensionProps, IHelloWorldAdaptiveCardExtensionState> {
      // Use the Card button to open the Quick View
      public get cardButtons(): [ICardButton] {
        return [
            title: 'View All',
            action: {
              type: 'QuickView',
              parameters: {
                view: QUICK_VIEW_REGISTRY_ID
      // Display the total number of steps
      public get data(): IBasicCardParameters {
        return {
          primaryText: `${this.state.items.length} Steps`
  3. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/HelloWorldAdaptiveCardExtension.ts.

  4. Now, register the new View by making the following changes to your ACE:

    import { MediumCardView } from './cardView/MediumCardView';
    const MEDIUM_VIEW_REGISTRY_ID: string = 'HelloWorld_MEDIUM_VIEW';
    public onInit(): Promise<void> {
      // ...
      this.cardNavigator.register(CARD_VIEW_REGISTRY_ID, () => new CardView());
      this.cardNavigator.register(MEDIUM_VIEW_REGISTRY_ID, () => new MediumCardView());
      // ...
  5. Update the renderCard() method to return either the Medium Card View or the Large Card View based on the Card size:

    protected renderCard(): string | undefined {
      return this.cardSize === 'Medium' ? MEDIUM_VIEW_REGISTRY_ID : CARD_VIEW_REGISTRY_ID;

Test your changes by refreshing the workbench:

Change the Card size to Large and refresh the browser:

Large Card interactivity

ACE Card views support user interaction. The buttons can invoke REST APIs or be used to interact with the Card in other ways. In this section, you'll change the Large Card view to iterate through the items in the SharePoint list.

  1. Locate and open the following file in the project: ./src/adaptiveCardExtensions/helloWorld/cardView/CardView.ts.

  2. At the top of the file, add IActionArguments as one of the references to import from the @microsoft/sp-adaptive-card-extension-base package:

    import { IActionArguments } from '@microsoft/sp-adaptive-card-extension-base';
  3. The buttons on the Card view can be dynamic based on the current state of the ACE. Add the following code to your ACE's CardView.ts file:

    public get cardButtons(): [ICardButton] | [ICardButton, ICardButton] {
      const buttons: ICardButton[] = [];
      // Hide the Previous button if at Step 1
      if (this.state.currentIndex > 0) {
          title: 'Previous',
          action: {
            type: 'Submit',
            parameters: {
              id: 'previous',
              op: -1 // Decrement the index
      // Hide the Next button if at the end
      if (this.state.currentIndex < this.state.items.length - 1) {
          title: 'Next',
          action: {
            type: 'Submit',
            parameters: {
              id: 'next',
              op: 1 // Increment the index
      return buttons as [ICardButton] | [ICardButton, ICardButton];
  4. Next, update the state when a button is selected by implementing the following method:

    public onAction(action: IActionArguments): void {
      if (action.type === 'Submit') {
        const { id, op } =;
        switch (id) {
          case 'previous':
          case 'next':
          this.setState({ currentIndex: this.state.currentIndex + op });

Test your changes by reloading the workbench in your browser.

The first instance of the card will show the first list item with a Next button:

First view of the card with the Next button

Select the Next button. The card will display the next item in the list and add a Previous button:

Card displaying a SharePoint list item that's neither the first or last item in the list

Select the Next button until you get to the last item in the list. The card will display the item in the list and only display the Previous button:

Card displaying the last item in the list with only a Previous button

Caching Card view and ACE state

Starting in SPFx v1.14, ACEs have a client-side caching layer that can be configured to store:

  1. The latest rendered card.
  2. The state of the ACE.

Rendering from cached Card view

If the latest rendered card is stored, the Dashboard renders this cached card before the ACE is initialized, improving perceived performance.

The settings for this cache can be configured by overriding the following method:

protected getCacheSettings(): Partial<ICacheSettings> {
  return {
    isEnabled: true, // can be set to false to disable caching
    expiryTimeInSeconds: 86400, // controls how long until the cached card and state are stale
    cachedCardView: () => new CardView() // function that returns the custom Card view that will be used to generate the cached card

Rehydrating from cached ACE state

The subset of the ACE state that is cached can be configured by overriding the following method:

protected getCachedState(state: TState): Partial<TState>;

The object returned by this method will be serialized and cached. By default, no state is cached. In the next call to onInit, the deserialized value will be passed to onInit as part of the ICachedLoadParameters

public onInit(cachedLoadParameters?: ICachedLoadParameters): Promise<void>;

The value can then be used to rehydrate the state of the newly initialized ACE.


After this lab you should be familiar with:

  • Changing the default properties of an ACE
  • Changing the ACE properties/state interfaces
  • Creating and registering Card views
  • Conditionally rendering Card view elements
  • Advanced Card view manipulation
  • Caching Card view and ACE state
