How do I retrieve user input from a textbox after users hit the submit button?

Im having troubles retrieving textbox input in Xamarin using XAML and C#.

I want the user to enter their ID in a field, and after hitting the submit button, I can retrieve the value in the field.

Here's what I have so far:

XAML:

        <Entry x:Name="UserInput"
               Placeholder="Enter employee ID"
               PlaceholderColor="Gray"
               HorizontalOptions="Center"
               VerticalOptions="CenterAndExpand" />
        <Button Text="Submit"
                VerticalOptions="Center"
                Clicked="GetUserInput"/>

Xaml.CS:

        void GetUserInput(System.Object sender, System.EventArgs e)
        {
            var matchingPerson = UserInput.Text;
            Console.WriteLine(matchingPerson);

        }

 
        public MainPage()
        {
            InitializeComponent();
        }

However, when I call, matchingPerson = UserInput.Text, I can't access the value of UserInput. It's in a separate file and since its XAML there is no "namespace" for me to access it by.

How do I go about fetching the value of the UserInput textbox after users have entered their data in the field?

For whatever the reason, closing out of the solution and reopening it allowed it to run. Xamarin was somehow reporting a false error to me in the console. The code above is correct - Xamarin was being buggy. I forced quit all of my visual studio applications in activity monitor and opened them back up - that did the trick.

Your code is working fine in my side it's the issue in xamarin.forms 4.7 to get x:name in code behind

My xamarin.forms is 4.5.0.495

Xmal:

<StackLayout VerticalOptions="CenterAndExpand">
   <Entry x:Name="UserInput"
           Placeholder="Enter employee ID"
           PlaceholderColor="Gray"
           HorizontalOptions="Center"
           VerticalOptions="CenterAndExpand" />
    <Button Text="Submit"
            VerticalOptions="Center"
            Clicked="GetUserInput"/>
    
</StackLayout>

Code behind:

void GetUserInput(System.Object sender, System.EventArgs e)
    {
        var matchingPerson = UserInput.Text;
        Console.WriteLine(matchingPerson);
    }
