Configuration Options

Configuring the DefaultableList

In the DefaultableList implementation found within the stevedunn/bindingtodefaultablelist, there are specific options that allow developers to configure the behavior of the list during development. Utilizing proper settings ensures that the list conforms to the intended use case.

Basic Configuration

To begin with the configuration, identify the DefaultableList class in your C# project and initialize it. Here is a basic example of how you can set it up:

using BindingToDefaultableList;

public class ExampleUsage
{
    public void InitializeList()
    {
        var myDefaultableList = new DefaultableList<MyType>();
        myDefaultableList.Add(new MyType { Property = "Value1" });
        myDefaultableList.Add(new MyType { Property = "Value2" });

        // Setting a default value
        myDefaultableList.SetDefault(new MyType { Property = "DefaultValue" });
    }
}

Customizing Item Behavior

Beyond the basic setup, you can customize the behavior of the items within the list. For instance, if you need to react to changes in items, you can subscribe to collection changed events:

using BindingToDefaultableList;
using System.Collections.Specialized;

public class ExampleUsageWithEvents
{
    public void InitializeAndSubscribe()
    {
        var myDefaultableList = new DefaultableList<MyType>();

        myDefaultableList.CollectionChanged += OnCollectionChanged;

        myDefaultableList.Add(new MyType { Property = "Value1" });
        myDefaultableList.Add(new MyType { Property = "Value2" });
    }

    private void OnCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        // Handle the changes in the collection here
        if (e.Action == NotifyCollectionChangedAction.Add)
        {
            foreach (MyType newItem in e.NewItems)
            {
                // Process the new item
            }
        }
    }
}

Implementing Default Value Logic

The functionality to set a default value is critical for the operation of the list. You can determine logic based on the default item, and use it accordingly in your application. Here’s how to work with the default value:

public class ExampleWithDefaultLogic
{
    private DefaultableList<MyType> myDefaultableList;

    public ExampleWithDefaultLogic()
    {
        myDefaultableList = new DefaultableList<MyType>();
        myDefaultableList.SetDefault(new MyType { Property = "DefaultValue" });

        // Accessing the default item
        var defaultItem = myDefaultableList.Default;

        // Conditional logic based on default item
        if (defaultItem != null)
        {
            // Perform actions with defaultItem
        }
    }
}

Advanced Features

To leverage advanced features such as binding to UI components, ensure that your list implementation correctly handles property notifications. This might look as follows:

using BindingToDefaultableList;

public class BindingExample
{
    public DefaultableList<MyType> MyList { get; private set; }

    public BindingExample()
    {
        MyList = new DefaultableList<MyType>();
        MyList.Add(new MyType { Property = "Item1" });
        MyList.SetDefault(new MyType { Property = "DefaultItem" });

        // Further access and UI binding can be implemented here.
    }
}

Conclusion

Effective configuration of the stevedunn/bindingtodefaultablelist within your development environment enables refined control over default values and item interactions. By utilizing events, defaults, and proper bindings, the implementation can cater to complex application requirements.
