I am using Bot Framework .Net SDK v4 adaptive card v1.2. I am using waterfall design to show cards in each step of waterfall. But user is able to click buttons from previously shown cards and this makes the bot look dumb.
How can I disable/Hide adaptive card buttons from previous chat in bot framework in c#?
Web Chat has a sample that shows you how to disable Adaptive Cards on the client side: https://github.com/microsoft/BotFramework-WebChat/blob/master/samples/05.custom-components/l.disable-adaptive-cards/index.html
If you want to disable cards on the bot side then you'll need to use bot state to remember which cards are still clickable. You can read about bot state here: https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-concept-state
I'm working on a library that can do this for you automatically. You can voice your support for the library if you want it to be released sooner. The page currently contains no fewer than 9 links to issues just like yours where people want to disable cards: https://github.com/BotBuilderCommunity/botbuilder-community-dotnet/issues/137
