Solution

Since you had used Data-binding(MVVM) .It would better to handle the logic by using Command . In addition, we could pass the text of label(or the whole model) instead of the Label itself .

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="App11.MainPage"
             x:Name="page"> // set the name of the page

<ImageButton Grid.Column="2"
                       Grid.Row="0"
                       HorizontalOptions="End"
                       VerticalOptions="End"
                       Source="plus.png"
                       Margin="9"
                       BackgroundColor="Transparent"
                       Command="{Binding Source={x:Reference page},Path=BindingContext.xxxCommand}}"  
                       CommandParameter="{Binding .}"
                     />

in your viewmodel

public ICommand xxxCommand { get; set; }

xxxCommand = new Command((arg)=> {

  //var model = arg as YourModel;
  // you can get the text of label from the model and do something you want 
});
