How to change the default button label “No Preference” in FormFlow

问题

Is there a way to modify the default "No Preference" label of the button when updating the user inputs to read e.g. "I don't want to change anything." without introducing a new Resources.*.resx file?

I tried all templates that allow changing such literals but I found no one that could achieve this. TemplateUsage.NoPreference can be used to change only the value of an optional field, not the button label.

You can do it by overriding the Template value in your FormFlow.

Here is an example based on the Microsoft.Bot.Sample.SimpleSandwichBot:

public static IForm<SandwichOrder> BuildForm()
{
    var formBuilder = new FormBuilder<SandwichOrder>()
            .Message("Welcome to the simple sandwich order bot!");

    var noPreferenceStrings = new string[] { "Nothing" };

    // Set the new "no Preference" value
    formBuilder.Configuration.Templates.Single(t => t.Usage == TemplateUsage.NoPreference).Patterns = noPreferenceStrings;

    // Change this one to help detection of what you typed/selected
    formBuilder.Configuration.NoPreference = noPreferenceStrings;

    return formBuilder.Build();
}
