Making Payments Easy: Using .NET MAUI Radio Button for Payment Apps and Digital Wallets

“Good design is good business.”

– Thomas J. Watson Jr.

In today’s fast-paced digital world, payment apps and digital wallets have become essential tools for managing finances and making transactions. These applications offer convenience, speed, and security, allowing us to complete purchases with just a few taps on our smartphones.

With the rise of e-commerce and online shopping, a seamless and intuitive payment selection interface is crucial.

In this blog, we’ll explore how to implement a streamlined payment selection interface using the Syncfusion .NET MAUI Radio Button.

Syncfusion .NET MAUI Radio Button: An overview

The .NET MAUI Radio Button is a selection control that enables users to choose a single option from a set of pre-defined choices. Its key features include:

• States: It has two selection states: Checked and Unchecked.
• Grouping: Radio buttons can be grouped within any layout.
• Customizations: You can customize the checked and unchecked colors, stroke thickness, and text appearance.
• Single selection: It allows us to select only one option from a set, ensuring that users make a single choice.

Choosing the right payment method

A payment app offers various payment options, such as credit/debit cards, UPI, or bank transfers. Encouraging users to pick their preferred payment method is essential for a smooth checkout experience.

Here, we will use our Syncfusion .NET MAUI Radio Button to implement the payment selection interface. Refer to the following image.

Integrating Syncfusion .NET MAUI Radio Button to simplify payment method selection

Follow the steps to design and implement payment method selection UI using the .NET MAUI Radio Button.

Step #1: Create a simple .NET MAUI Radio Button

Start by referring to the Syncfusion .NET MAUI Radio Button documentation to create a .NET MAUI app and include the Radio Button control. The IsChecked property indicates whether a specific payment method is selected among the available options.

<buttons:SfRadioButton Text="UPI" IsChecked="True"/>

Step #2: Group Radio Buttons

You can group a set of radio buttons using the SfRadioGroup class. This class is a container that ensures only one radio button is selected within the same group.

<buttons:SfRadioGroup>
     <buttons:SfRadioButton Text="UPI" IsChecked="True" />
     <buttons:SfRadioButton Text="Credit/Debit/ATM Card" />
     <buttons:SfRadioButton Text="Net Banking" />
     <buttons:SfRadioButton Text="Cash on Delivery" />
 </buttons:SfRadioGroup>

Step #3: Select payment options

Let’s implement the code to choose any of the available payment options and take the necessary actions in the StateChanged event. This event is triggered when the IsChecked state changes.

XAML

<buttons:SfRadioGroup>
    <buttons:SfRadioButton Text="UPI" StateChanged="PaymentOption_Selected" IsChecked="True"/>
    <buttons:SfRadioButton Text="Credit/Debit/ATM Card" StateChanged="PaymentOption_Selected"/>
    <buttons:SfRadioButton Text="Net Banking" StateChanged="PaymentOption_Selected"/>
    <buttons:SfRadioButton Text="Cash on Delivery" StateChanged="PaymentOption_Selected"/>
</buttons:SfRadioGroup>

C#

private void PaymentOption_Selected(object sender, StateChangedEventArgs e)
{
     // Add your code here.
}

Step #4: Customize the payment form

In this example, we’ll enhance the payment form UI by adding text input layout controls for entering the name, mobile number, and email ID. Additionally, we’ll create separate sections for each payment option, as shown below.

Refer to the code example in the GitHub repository.
