ListViewProperty

This is a BindableProperty used when declaring bindings for ListView.

How to Declare

As with BindableProperty, you can declare by calling ListViewProperty<T>.Create().

private static readonly ListViewProperty<AlarmInfoViewModel> ListDataSourceProperty =
    ListViewProperty<AlarmInfoViewModel>.Create(
        itemViewId: AlarmInfoLayout.UxmlGuid,
        makeItemSource: MakeItem,
        itemsSourcePath: PropertyPath.FromName(nameof(AlarmInfoListViewModel.Current)),
        elementNameInfo: ElementNames.AlarmsList
    );

private static AlarmInfoViewModel MakeItem(int index)
{
    var newInfo = new AlarmInfo
    {
        isEnabled = true,
        id = Guid.NewGuid().ToString(),
        info = $"Alarm {index + 1}",
        timeStringIso8601 = DateTime.Now.ToString("yyyy-MM-dd'T'HH:mm:sszzz"),
    };
    return new AlarmInfoViewModel(newInfo);
}

Parameters

TabViewProperty<T>.Create() can specify the following parameters:

Parameter	Type	Required	Default Value
itemViewId	string	yes	-
makeItemSource	MakeItemSourceDelegate	yes	-
itemsSourcePath	PropertyPath	yes	-
elementNameInfo	ElementNameInfo	yes	-
bindingMode	BindingMode	no	BindingMode.ToTarget
updateTrigger	BindingUpdateTrigger	no	BindingUpdateTrigger.OnSourceChanged

• itemViewId
  Specifies the Guid of the View class. For the assembly containing the View class with the specified Guid, you need to call ViewInstaller.Install() in advance. In ListView.makeItem, this Guid is used to obtain and instantiate a VisualTreeAsset, and data binding is executed by the View class.

• makeItemSource
  Defines how to create the contents of itemsSource when ListView.bindItem is triggered.
  The result of the process specified by makeItemSource becomes the data source for each item in the ListView.

• elementNameInfo
  Specifies which ListView to construct the binding for.

• bindingMode
  Specifies BindingMode.

• updateTrigger
  Specifies BindingUpdateTrigger.
