Bot Framework (v4) - How To Get State From Custom Prompt Validation

I'm implementing a custom prompt validation where I need to access my state to compare with the user's input. I did a lot of search and microsoft documentation and some samples too

Solution 1:

If the only reason AddressTextPrompt extends TextPrompt is so that you can do validation, then you should really just pass a validator in to a TextPrompt.

In the Multi-Turn-Prompt Sample,

...it passes in the validator:

this.addDialog(newNumberPrompt(NUMBER_PROMPT, this.agePromptValidator));

...then performs the validation:

asyncagePromptValidator(promptContext) {
    // This condition is our validation rule. You can also change the value at this point.return promptContext.recognized.succeeded && promptContext.recognized.value > 0 && promptContext.recognized.value < 150;
}

If the validator returns false, then the retryPrompt is fired. Otherwise, activity.Text is passed to the next step like normal. For you, the validator might look something like:

asyncaddressValidator(promptContext) {
    constuserState: State = awaitthis.userProfile.get(context);
    // This condition is our validation rule. You can also change the value at this point.return promptContext.recognized.succeeded && promptContext.recognized.value === userState.user.address;
}
