Getting Started With Adaptive Card Design Using Microsoft Bot Framework

Introduction

 
The Bot Framework supports different types of rich cards and provides a richer interaction experience to the user. In this article, I will show how to integrate adaptive card UI design in a Bot application. The Adaptive Card contains a combination of text, speech, images, buttons, and input controls. Adaptive Cards are created using the JSON format specified in the Adaptive Cards schema and Microsoft provided Microsoft.AdaptiveCards NuGet package for .NET Developer to building cards and handles the serialization.

Create New Bot Application
 
Let's create a new bot application using Visual Studio 2017. Open Visual Studio > Select File > Create New Project (Ctrl + Shift +N) > Select Bot application.
 
Microsoft Bot Framework
 
The Bot application template gets created with all the components and all required NuGet references installed in the solutions.
 
Microsoft Bot Framework
 
Install AdaptiveCard Nuget package
 
Microsoft.AdaptiveCards library implements classes for building and serializing adaptive card objects and Visual Studio IntelliSense will help us to implement Adaptive cards in the bot application.
 
Right-click on Solution, select Manage NuGet Package for Solution > Search “ Microsoft AdaptiveCards” > select Project and install the package.
 
Microsoft Bot Framework
 
Create New AdaptiveCardDialog Class
 
Step 1
 
You can create a new AdaptiveCardDialog class to show the Adaptive dialog. Rightclick on Project, select Add New Item, create a class that is marked with the [Serializable] attribute (so the dialog can be serialized to state), and implement the IDialog interface.
  1. using System;  
  2. using System.Threading.Tasks;  
  3. using Microsoft.Bot.Builder.Dialogs;  
  4. using Microsoft.Bot.Connector;  
  5. using System.IO;  
  6. using System.Web;  
  7. using System.Collections.Generic;  
  8.   
  9. namespace BotAdaptiveCard.Dialogs  
  10. {  
  11.     [Serializable]  
  12.     public class AdaptiveCardDialog: IDialog<object>  
  13.     {   
Step 2
 
IDialog interface has only StartAsync() method. StartAsync() is called when the dialog becomes active. The method passes the IDialogContext object, used to manage the conversation.
  1. public async Task StartAsync(IDialogContext context)  
  2.         {  
  3.             context.Wait(this.MessageReceivedAsync);  
  4.         } 
Step 3
 
Create a MessageReceivedAsync method and write the following code for the welcome message and to show the list of the demo options dialog.
  1. [Serializable]  
  2.  public class AdaptiveCardDialog : IDialog<object>  
  3.  {  
  4.      public Task StartAsync(IDialogContext context)  
  5.      {  
  6.          context.Wait(this.MessageReceivedAsync);  
  7.          return Task.CompletedTask;  
  8.      }  
  9.      private readonly IDictionary<string, string> options = new Dictionary<string, string>  
  10.   
  11.  { "1""1. Show Demo Adaptive Card " },  
  12.  { "2""2. Show Demo for Adaptive Card Design with Column" },  
  13.  {"3" , "3. Input Adaptive card Design" }  
  14.   
  15.      };  
  16.      public async virtual Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)  
  17.      {  
  18.          var message = await result;  
  19.          var welcomeMessage = context.MakeMessage();  
  20.          welcomeMessage.Text = "Welcome to bot Adaptive Card Demo";  
  21.   
  22.          await context.PostAsync(welcomeMessage);  
  23.   
  24.          this.DisplayOptionsAsync(context);  
  25.      }  
  26.   
  27.      public void DisplayOptionsAsync(IDialogContext context)  
  28.      {  
  29.          PromptDialog.Choice<string>(  
  30.              context,  
  31.              this.SelectedOptionAsync,  
  32.              this.options.Keys,  
  33.              "What Demo / Sample option would you like to see?",  
  34.              "Please select Valid option 1 to 6",  
  35.              6,  
  36.              PromptStyle.PerLine,  
  37.              this.options.Values);  
  38.      }  
  39.      public async Task SelectedOptionAsync(IDialogContext context, IAwaitable<string> argument)  
  40.      {  
  41.          var message = await argument;  
  42.   
  43.          var replyMessage = context.MakeMessage();  
  44.   
  45.          Attachment attachment = null;  
  46.   
  47.          switch (message)  
  48.          {  
  49.              case "1":  
  50.                  attachment = CreateAdapativecard();  
  51.                  replyMessage.Attachments = new List<Attachment> { attachment };  
  52.                  break;  
  53.              case "2":  
  54.                  attachment = CreateAdapativecardWithColumn();  
  55.                  replyMessage.Attachments = new List<Attachment> { attachment };  
  56.                  break;  
  57.              case "3":  
  58.                  replyMessage.Attachments = new List<Attachment> { CreateAdapativecardWithColumn(), CreateAdaptiveCardwithEntry() };  
  59.                  break;  
  60.   
  61.          }  
  62.           
  63.   
  64.          await context.PostAsync(replyMessage);  
  65.   
  66.          this.DisplayOptionsAsync(context);  
  67.      } 
After the user enters the first message, our bot will reply with a welcome message and list of demo options. Then, it waits for user input like below.
 
Microsoft Bot Framework
 
Step 4 Design Adaptive Card
 
The Adaptive Cards are created using JSON but with Microsoft.AdaptiveCards NuGet, we can create them by composing card objects. We can create AdaptiveCard objects and attach to the attachment and post message to a message.
 
Microsoft Bot Framework
 
The following code shows the design of the welcome message with image, textblock, and speech.
  1. public Attachment CreateAdapativecard()  
  2.       {  
  3.   
  4.           AdaptiveCard card = new AdaptiveCard();  
  5.   
  6.           // Specify speech for the card.  
  7.           card.Speak = "Suthahar J is a Technical Lead and C# Corner MVP. He has extensive 10+ years of experience working on different technologies, mostly in Microsoft space. His focus areas are  Xamarin Cross Mobile Development ,UWP, SharePoint, Azure,Windows Mobile , Web , AI and Architecture. He writes about technology at his popular blog http://devenvexe.com";  
  8.           // Body content  
  9.           card.Body.Add(new Image()  
  10.           {  
  11.               Url = "https://i1.social.s-msft.com/profile/u/avatar.jpg?displayname=j%20suthahar&size=extralarge&version=88034ca2-9db8-46cd-b767-95d17658931a",  
  12.               Size = ImageSize.Small,  
  13.               Style = ImageStyle.Person,  
  14.               AltText = "Suthahar Profile"  
  15.   
  16.           });  
  17.   
  18.           // Add text to the card.  
  19.           card.Body.Add(new TextBlock()  
  20.           {  
  21.               Text = "Technical Lead and C# Corner MVP",  
  22.               Size = TextSize.Large,  
  23.               Weight = TextWeight.Bolder  
  24.           });  
  25.   
  26.           // Add text to the card.  
  27.           card.Body.Add(new TextBlock()  
  28.           {  
  29.               Text = "[email protected]"  
  30.           });  
  31.   
  32.           // Add text to the card.  
  33.           card.Body.Add(new TextBlock()  
  34.           {  
  35.               Text = "97XXXXXX12"  
  36.           });  
  37.   
  38.           // Create the attachment with adapative card.  
  39.           Attachment attachment = new Attachment()  
  40.           {  
  41.               ContentType = AdaptiveCard.ContentType,  
  42.               Content = card  
  43.           };  
  44.           return attachment;  
  45.       }  
The above code will generate following adaptive card and reply to the user
 
Microsoft Bot Framework
 
Step 5 Design Adaptive Card with Column:
 
The Adaptive Cards contain many elements that allow designing UI content in a common and consistent way.
  1. Container - A Container is a CardElement which contains a list of CardElements that are logically grouped.
  2. ColumnSet and Column - The columnSet element adds the ability to have a set of Column objects and align the column object.
  3. FactSet - The FactSet element is displayed row and column like a tabular form.
  4. TextBlock - The TextBlock element allows for the inclusion of text, we can modify font sizes, weight, and color.
  5. ImageSet and Image - The ImageSet allows for the inclusion of collection images like a photo set, and the Image element allows for the inclusion of images.
Microsoft Bot Framework
 
The following code shows adding multiple columns and design of the UI Adaptive Card.
  1. public Attachment CreateAdapativecardWithColumn()  
  2.         {  
  3.             AdaptiveCard card = new AdaptiveCard()  
  4.             {  
  5.                 Body = new List<CardElement>()  
  6.     {  
  7.         // Container  
  8.         new Container()

Step 6 Adaptive Card Design with Input Control
 
The Adaptive Cards can include input controls for collecting the information from the user. It will support the following input controls - Text, Date, Time, Number, and for selecting options(choice set) and toggle.
 
The following sample code is included collecting basic information from the users with an action button.
  1. Text – Collect the text content from the user
  2. Date - Collect a Date from the user
  3. Time - Collect a Time from the user
  4. Number - Collect a Number from the user
  5. ChoiceSet - provide the user with a set of choices and have them pick
  6. ToggleChoice - provide the user with a single choice between two items and have them pick
  1. public Attachment CreateAdaptiveCardwithEntry()  
  2.         {  
  3.             var card = new AdaptiveCard()  
  4.             {  
  5.                 Body = new List<CardElement>()  
  6.               {  
  7.             // Hotels Search form  
  8.             
  9.             new TextBlock() { Text = "Please Share your detail for contact:" },  
  10.             new TextInput()  
  11.             {  
  12.                 Id = "Your Name",  
  13.                 Speak = "<s>Please Enter Your Name</s>",  
  14.                 Placeholder = "Please Enter Your Name",  
  15.                 Style = TextInputStyle.Text  
  16.             },

  27.                 Min = 1,  
  28.                 Max = 20,  
  29.             },  
  30.             new TextBlock() { Text = "Email" },  
  31.             new TextInput()

  60.                 Content = card  
  61.             };  
  62.             return attachment;  
  63.         }  
The above code will return the following adaptive card design.
