public interface class IListSource

NameDescription
System_CAPS_pubpropertyContainsListCollection

Gets a value indicating whether the collection is a collection of IList objects.

NameDescription
System_CAPS_pubmethodGetList()

Returns an IList that can be bound to a data source from an object that does not implement an IList itself.

You typically use this interface to return a list that can be bound to a data source, from an object that does not implement IList itself.

Binding to data can occur at either run time or in a designer, but there are rules for each. At run time, you can bind to data in any of the following:

  • Array

  • Implementer of IList, provided the implementer has a strongly typed Item property (that is, the Type is anything but Object). You can accomplish this by making the default implementation of Item private. If you want to create an IList that follows the rules of a strongly typed collection, you should derive from CollectionBase.

  • Implementer of ITypedList.

In a designer, you can initialize binding to Component objects by following the same rules.

System_CAPS_noteNote

Implementers of IListSource can return an IList that contains a collection of IList objects.

The following code example demonstrates how to implement the IListSource interface. A component named EmployeeListSource exposes an IList for data binding by implementing the GetList method. For a full code listing, see How to: Implement the IListSource Interface.

No code example is currently available or this language may not be supported.
