Creating a Registration page, I need to get the following data from user.

* First Name
* Last Name
* Username
* Email
* Password
* Date of Birth
* **Gender**
* **User Role**

For the last two parameters, I am unable to find how to use radio buttons in Xamarin.Forms. Following is my code for the Registration Page.

```
<StackLayout BackgroundColor="#30af91" Padding="60">

<Entry Text="{Binding FirstName}" Placeholder="First Name"/>
<Entry Text="{Binding LastName}" Placeholder="Last Name"/>
<Entry Text="{Binding UserName}" Placeholder="Last Name"/>
<Entry Text="{Binding Email}" Placeholder="Email" />
<Entry Text="{Binding Password}" Placeholder="Password" IsPassword="True"/>
<Entry Text="{Binding ConfirmPassword}" Placeholder="Confirm Password" IsPassword="True"/>
<DatePicker MinimumDate="1/1/1948" MaximumDate="12/31/2007"/>

<!--Radio buttons for Gender
    1. Male   2.Female-->

<!--Radio Buttons for UserRole
    1. Admin  2.Participant-->

<Button Command="{Binding RegisterCommand}" Text="Register"/>
<Label Text="{Binding Message}" />

</StackLayout>

```
