ITypedList.GetItemProperties Method

Returns the PropertyDescriptorCollection that represents the properties on each item used to bind data.

Namespace: System.ComponentModel
Assembly: System (in system.dll)

PropertyDescriptorCollection GetItemProperties (
	PropertyDescriptor[] listAccessors
PropertyDescriptorCollection GetItemProperties (
	PropertyDescriptor[] listAccessors
function GetItemProperties (
	listAccessors : PropertyDescriptor[]
) : PropertyDescriptorCollection
Not applicable.



An array of PropertyDescriptor objects to find in the collection as bindable. This can be a null reference (Nothing in Visual Basic).

Return Value

The PropertyDescriptorCollection that represents the properties on each item used to bind data.

If the listAccessors parameter is not a null reference (Nothing in Visual Basic), it typically contains a property descriptor that identifies a list of containers to retrieve for the object that implements ITypedList. For example, a DataSet containing two tables, myCustomers and myOrders, with a relationship between them called myCustOrders. If you create a DataView object to view myCustomers, then calling the GetItemProperties method with a null reference (Nothing in Visual Basic) returns the property descriptors for the columns in myCustomers. As a result, one of the returned property descriptors is a property descriptor for myCustOrders, just as calling the GetItemProperties method with a list accessor array containing the property descriptors for myCustOrders will return the property descriptors for myOrders.

The following code example demonstrates how to implement the GetItemProperties method. For a full code listing, see How to: Implement the ITypedList Interface.

public PropertyDescriptorCollection GetItemProperties(PropertyDescriptor[] listAccessors)
    PropertyDescriptorCollection pdc = null;

    if (null == listAccessors)
        // Return properties in sort order.
        pdc = properties;
        // Return child list shape.
        pdc = ListBindingHelper.GetListItemProperties(listAccessors[0].PropertyType);

    return pdc;
