Bot Framework (.Net) - Send additional parameters with button using PromptDialog.Choice()

I'm trying to learn Bot Framework using .Net and I have an application which displays buttons and based on the option selected, display more buttons or a list. What I want is, to send a hidden ID/parameter with the button so that when user clicks on the button, I can access the hidden parameter. I'm not using cards for this. I just want to display the buttons. Can anyone help me with this? I know this can be a very basic question but I couldn't find how to this without Cards.

First of all, PromptDialog.Choice behind the scenes creates a HeroCard with multiple buttons (which are basically the PromptOptions passed, see the code)

One way to pass a hidden parameter would be specifying the ActionType PostBack to your button and fill the Value property with the hidden parameter. PostBack is the way to go here since the message will be posted to the bot but client applications will not display this message (however, please note that not all the channels support the postBack action type). See this for more information

Now, since you are using PromptDialog.Choice you will have to override things in order to be able to specify the PostBack action type, since by default, the buttons created with the Choice are using ImBack (per this code)

You will have to put together a custom PromptStyler, override the Apply<T> method and add your logic to change the action type and set the buttons in the way you want based on the PromptStyle used and pass that custom styler to the PromptDialog.Choice.

By default the PromptDialog.Choice uses PromptStyle.Auto.
