Answer 1

You can update adaptive card in channel like MS Teams not in directline. For updating card you need Accessor to store ActivityId which is generated while sending current message.

Here I have provided the way to update message

This involves few steps.

1. Create an Adaptive card and add unique id (GUID) in adaptive card action.

   var Card = new AdaptiveCard()
   {
         Body = new List<AdaptiveElement>()
   {
       new AdaptiveTextBlock(){Text="This is a test adaptive card"}
   },
   Actions = new List<AdaptiveAction>()
   {
       new AdaptiveSubmitAction()
       {
           Title="UpdateMe",
           DataJson= @"{'id':'uniqueId'}"
       }
   }
   };
   

2. After sending message keep mapping of adaptive card uniqueId and message id.

   connector = new ConnectorClient(new Uri(activity.ServiceUrl));
   reply = activity.CreateReply();
   reply.Attachments.Add(Card.ToAttachment());
   var msgToUpdate = await connector.Conversations.ReplyToActivityAsync(reply);
   // Keep mapping of uniqueId and messageToUpdate.Id
   // UniqueId1 => messageId1
   // UniqueId2 => messageId2
   

3. When user clicks on UpdateMe action button, check the mapping for uniqueId (This will be in activity.Value).

4. Create new card and call connector.Conversations.UpdateActivityAsync with updated code.
