title: How to create adaptive cards with situational text values?
body: <p>I am currently trying to create an adaptive card in a Waterfall Dialog for one of my bots that will display the name and search item (both strings) when rendered. Both of the values I want to use are stored in the Context.Activity.Value property of my dialog, so all I need to know is how to insert those values into my adaptive card at some point during its creation so that the "text" values of the text blocks can contain my values.</p>
  
  <p>I have looked into using empty JSON objects in the adaptive card schema that I could fill somehow during the adaptive card's creation, but have not figured out how to insert said values. I'm a relative beginner with C# and Bot Framework, so I don't know what to try.</p>
  
  <p>Below is the step in my Waterfall Dialog where the adaptive card is made:</p>
  
  <pre><code>private async Task&lt;DialogTurnResult&gt; AdaptiveCardTest(WaterfallStepContext stepContext, 
  CancellationToken cancellationToken)
          {
              var introCard = File.ReadAllText("./Content/AdaptiveCardTest.json");
  
              var card = AdaptiveCard.FromJson(introCard).Card;
              var attachment = new Attachment(AdaptiveCard.ContentType, content: card);
  
              var response = MessageFactory.Attachment(attachment, ssml: card.Speak, 
              inputHint: InputHints.AcceptingInput);
  
              await stepContext.Context.SendActivityAsync(response);
  
              return await stepContext.NextAsync();
          }
  </code></pre>
  
  <p>AdaptiveCardTest.json is the adaptive card's json file. At the moment it just has an image popup with some text which includes placeholders where I would like the user name and search item to go. The placeholder links are there because the actual links are ridiculously long.</p>
