Can form flow fields in bot framework be pre-populated?

问题

I have used formflow to ask several questions and to finally fill up a form. A unique id is generated and given to user at the end. Now using that unique id I want to edit the form. Is it possible to pre-populate the fields? Or is there any other way to do so?

This is the code that I am using to create a form for first time:

public static IForm<AssesmentHelper> BuildForm()
{
    OnCompletionAsyncDelegate<AssesmentHelper> wrapUpRequest = async (context, state) =>
    {
       //Do something....
    };

    return new FormBuilder<AssesmentHelper>()
            .Message(Responses.NumberSelection)
            .Field(nameof(Name))
            .Field(nameof(Age))
            .Field(nameof(Address))
            .Field(nameof(Information))
            .Field(nameof(Email), validate: ValidateMailId)
            .AddRemainingFields()
            .OnCompletion(wrapUpRequest)
            .Build();
}

Now, I want to pre-populate fields (Name, Age, Address) so that I can use it for editing as well.

Yes, you can pass an instance of your Form state/model to the FormDialog with the Form parameters pre-filled (as you can see here). Have in mind that . if you do that, any step for filling a field is skipped if that field has a value.

If you still want to ask for those parameters even if they have a value; you must change the FormOptions and use FormOptions.PromptFieldsWithValues, which will prompt for fields, but use the passed in state for defaults.

The relevant docs for this are here.

Sure you can pre-populate the formflow fields Firstly you will look for the fields that you want to populate and then add them to the entity list

I am using LUIS and if i find a suitable entity from my LUIS result i will add it to the form to be pre-populated.

 var entities = new List<EntityRecommendation>(result.Entities);
  if (entities.Any(e => e.Type == "IdNumber"))
        {
            entities.Add(new EntityRecommendation(type: "IdNumber") { Entity = entities.FirstOrDefault(e => e.Type == "IdNumber").Entity});
        }

This will be done before you call your form to be built. Just make sure your "type" is the property name of your class. "Entity" will be the value
