Text input in message dialog? ContentDialog?

Question

I am wondering what is the best way to allow a user to input text into a MessageDialog in a Windows 10 universal app.(Forgot password system). From the research I\'ve done this

Answer 1

Instead of Height=32, use this:

public static async Task ShowAddDialogAsync(string title)
    {
        var inputTextBox = new TextBox { AcceptsReturn = false };
        (inputTextBox as FrameworkElement).VerticalAlignment = VerticalAlignment.Bottom;
        var dialog = new ContentDialog
        {
            Content = inputTextBox,
            Title = title,
            IsSecondaryButtonEnabled = true,
            PrimaryButtonText = "Ok",
            SecondaryButtonText = "Cancel"
        };
        if (await dialog.ShowAsync() == ContentDialogResult.Primary)
            return inputTextBox.Text;
        else
            return "";
    }
