-# Payment-method-choice-using-.NET-MAUI-Radio-button
-This example demonstrates, how to implement a streamlined payment selection interface using Syncfusion Maui Radio buttons. 
+# Implementing Payment Method Selection:
+In this example, I will demonstrate how to implement payment method selection using the .NET Maui Radio button. Follow the steps below to create a project and implement payment selection from the available options using Maui Radio Buttons.
+
+## Create a Simple Maui RadioButton 
+
+Start by referring to the Syncfusion .NET MAUI RadioButton documentation to create a MAUI application and include the RadioButton components. The IsChecked property is used to indicate whether the payment method is selected among the available options.
+
+```
+<buttons:SfRadioButton Text="UPI" IsChecked="True"/>
+```
+
+## Group Radio Buttons
+
+You can group a set of radio buttons using a SfRadioGroup element. It's a container that ensures only one radio button can be 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>
+```
+
+##	Select Payment Options
+You can 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.
+
+```
+<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>
+```
+
+ ```
+private void PaymentOption_Selected(object sender, StateChangedEventArgs e)
+{
+     // Add your code here
+}
+
+```
+
+##	Customize the Payment Form
+In this example, I enhanced the payment form UI by adding text input layout controls for entering the name, mobile number, and email ID. Additionally, I created different sections for each payment option as shown below.
