Handling-User-Feedback-and-Errors-in-Maui-OTP-Input

This repository contains comprehensive samples on handling user feedback and errors effectively in the Maui OTP Input control, ensuring a seamless and user-friendly experience when users enter their One-Time Passwords (OTP). By providing real-time feedback, you can enhance the usability and reliability of your application, guiding users to correct mistakes promptly and maintaining high security standards throughout the authentication process. This guide aims to demonstrate effective techniques for managing user inputs, displaying appropriate feedback messages, and altering interface states based on the validation results.

Here’s an example approach:

XAML:

<StackLayout Padding="30" Spacing="20" HorizontalOptions="Center">
    <Label Text="Enter your OTP" FontSize="24" HorizontalOptions="Center" />
    <syncfusion:SfOtpInput x:Name="OtpInput" Length="6" />
    <Label x:Name="FeedbackLabel" IsVisible="False" Margin="20,0"/>
    <Button Text="Submit" Clicked="OnSubmitClicked" WidthRequest="150"/>
</StackLayout> 

C#:

private void OnSubmitClicked(object sender, EventArgs e)
{
   string enteredOtp = OtpInput.Value;
   if (string.IsNullOrEmpty(enteredOtp))
   {
       DisplayFeedback("OTP cannot be empty.");
       OtpInput.InputState = Syncfusion.Maui.Toolkit.OtpInput.OtpInputState.Warning;
   }
   else if (enteredOtp != "123456")
   {
       DisplayFeedback("Incorrect OTP. Please try again.");
       OtpInput.InputState = Syncfusion.Maui.Toolkit.OtpInput.OtpInputState.Error;
   }
   else
   {
       DisplayFeedback("OTP verified successfully!", true);
       OtpInput.InputState = Syncfusion.Maui.Toolkit.OtpInput.OtpInputState.Success;
   }
}

private void DisplayFeedback(string message, bool isSuccess = false)
{
   FeedbackLabel.Text = message;
   FeedbackLabel.TextColor = isSuccess ? Colors.Green : Colors.Red;
   FeedbackLabel.IsVisible = true;
}
