**XAML Intro
**
<Button Text="Click Me" Clicked="HandleButtonClick"/>
public void HandleButtonClick(object sender, EventArgs args)
{
    Console.WriteLine("You Clicked Me!");
}
**Building a text entry
**
<StackLayout>
    <Entry
        x:Name="TodoInput"
        Text=""
        TextChanged="HandleTextChanged"
        Completed="HandleTextCompleted"
    />
    
    <StackLayout x:Name="TodoList">

    </StackLayout>
</StackLayout>
public void HandleTextChanged(object sender, TextChangedEventArgs args)
{
    Console.WriteLine(args.NewTextValue);
}

public void HandleTextCompleted(object sender, EventArgs args)
{
    Label newTodo = new Label();
    newTodo.Text = TodoInput.Text;
    TodoList.Children.Add(newTodo);
    TodoInput.Text = "";
}
**MVVM Intro
**
Model is what defines what the actual data we’re working with looks like
View is the XAML
ViewModel connect these two things together

**Building the TodoItem Model
**
using System;
namespace AppPractice
{
    public class TodoItem
    {
        public string TodoText { get; set; }
        public bool Complete { get; set; }

        public TodoItem(string TodoText, bool Complete)
        {
            this.Text = TodoText;
            this.Complete = Complete;
        }
    }
}
**Building the TodoListViewModel
**
using System;
using System.Collections.ObjectModel;

namespace AppPractice
{
    public class TodoListViewModel
    {

        public ObservableCollection<TodoItem> TodoItems { get; set; };

        public TodoListViewModel()
        {
            TodoItems = new ObservableCollection<TodoItem>();

            TodoItems.Add(new TodoItem("First Todo", true));
        }
    }
}
**Wiring the ViewModel to the View
**
Don’t forget to remove all the old handlers and code
<ListView x:Name="TodoList" ItemsSource="{Binding TodoItems}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <Label Text="{Binding Text}"/>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

**Adding a new todo
**
using System.Windows.Input;
using Xamarin.Forms;
...

public ICommand AddTodoCommand => new Command(AddTodoItem);
public string NewTodoInputValue { get; set; }
void AddTodoItem()
{
    TodoItems.Add(new TodoItem(NewTodoInputValue, false));
}
<Entry
    x:Name="TodoInput"
    Text="{Binding NewTodoInputValue}"
    ReturnCommand="{Binding AddTodoCommand}"
/>
**Adding a trash icon
**
Download the trash icon
<FlexLayout JustifyContent="SpaceBetween" AlignItems="Center" Padding="20, 0">
    <Label Text="{Binding TodoText}"/>
    <ImageButton
        Source="delete.png"
        Scale="0.5"
        BackgroundColor="Transparent"   
    />
</FlexLayout>

**Removing a todo

**public ICommand RemoveTodoCommand => new Command(RemoveTodoItem);
void RemoveTodoItem(object o)
{
    TodoItem todoItemBeingRemoved = o as TodoItem;
    TodoItems.Remove(todoItemBeingRemoved);
}
<ImageButton
    Command="{Binding Path=BindingContext.RemoveTodoCommand, Source={x:Reference TodoList}}"
    CommandParameter="{Binding .}"
    Source="delete.png"
    Scale="0.5"
    BackgroundColor="Transparent"   
/>
**Adding a checkbox

**Manage NuGet Packages -> “Input Kit”
xmlns:input="clr-namespace:Plugin.InputKit.Shared.Controls;assembly=Plugin.InputKit"
...

<ContentView>
    <FlexLayout AlignItems="Center">
        <input:CheckBox
            IsChecked="{Binding Complete}"
        />
        <Label Text="{Binding TodoText}" Margin="20, 0"/>
    </FlexLayout>
</ContentView>

**Wiring up the toggle button

**<input:CheckBox
    IsChecked="{Binding Complete}"
/>
