ITypedList.GetItemProperties(PropertyDescriptor[]) ITypedList.GetItemProperties(PropertyDescriptor[]) ITypedList.GetItemProperties(PropertyDescriptor[]) ITypedList.GetItemProperties(PropertyDescriptor[]) Method

Definition

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

public:
 System::ComponentModel::PropertyDescriptorCollection ^ GetItemProperties(cli::array <System::ComponentModel::PropertyDescriptor ^> ^ listAccessors);
public System.ComponentModel.PropertyDescriptorCollection GetItemProperties (System.ComponentModel.PropertyDescriptor[] listAccessors);
abstract member GetItemProperties : System.ComponentModel.PropertyDescriptor[] -> System.ComponentModel.PropertyDescriptorCollection
Public Function GetItemProperties (listAccessors As PropertyDescriptor()) As PropertyDescriptorCollection

Parameters

listAccessors
PropertyDescriptor[]

An array of PropertyDescriptor objects to find in the collection as bindable. This can be null.

Returns

Examples

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;

    if (listAccessors!=null && listAccessors.Length>0)
    {
        // Return child list shape.
        pdc = ListBindingHelper.GetListItemProperties(listAccessors[0].PropertyType);
    }
    else
    {
        // Return properties in sort order.
        pdc = properties;
    }

    return pdc;
}
Public Function GetItemProperties(ByVal listAccessors() As System.ComponentModel.PropertyDescriptor) As System.ComponentModel.PropertyDescriptorCollection Implements System.ComponentModel.ITypedList.GetItemProperties

    Dim pdc As PropertyDescriptorCollection

    If (Not (listAccessors Is Nothing)) And (listAccessors.Length > 0) Then
        ' Return child list shape
        pdc = ListBindingHelper.GetListItemProperties(listAccessors(0).PropertyType)
    Else
        ' Return properties in sort order
        pdc = properties
    End If

    Return pdc

End Function

Remarks

If the listAccessors parameter is not null, 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 null 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.
