Защищенные методы

Метод	Описание
BindDataSource ( ) : void
BindListView ( ObjectListView olv ) : void
ChangePosition ( int index ) : void	Change the control's position (which is it's currently selected row) to the n'th row in the dataset
ConfigureColumn ( OLVColumn column, PropertyDescriptor property ) : void	Configure the given column to show the given property. The title and aspect name of the column are already filled in.
CreateColumnsFromSource ( ) : void	Create columns for the listview based on what properties are available in the data source This method will create columns if there is not already a column displaying that property.
CreateMissingAspectGettersAndPutters ( ) : void	Generate aspect getters and putters for any columns that are missing them (and for which we have enough information to actually generate a getter)
CurrencyManagerListChanged ( object sender, ListChangedEventArgs e ) : void	CurrencyManager ListChanged event handler. Deals with fine-grained changes to list items. It's actually difficult to deal with these changes in a fine-grained manner. If our listview is grouped, then any change may make a new group appear or an old group disappear. It is rarely enough to simply update the affected row.
HandleCurrencyManagerMetaDataChanged ( object sender, EventArgs e ) : void	The CurrencyManager calls this if the data source looks different. We just reload everything. CHECK: Do we need this if we are handle ListChanged metadata events?
HandleCurrencyManagerPositionChanged ( object sender, EventArgs e ) : void	Called by the CurrencyManager when the currently selected item changes. We update the ListView selection so that we stay in sync with any other controls bound to the same source.
HandleListChangedItemAdded ( ListChangedEventArgs e ) : void	Handle an ItemAdded event.
HandleListChangedItemChanged ( ListChangedEventArgs e ) : void	Handle ItemChanged event. This is triggered when a single item has changed, so just refresh that one item. Even in this simple case, we should probably rebuild the list. For example, the change could put the item into its own new group.
HandleListChangedItemDeleted ( ListChangedEventArgs e ) : void	Handle the ItemDeleted event
HandleListChangedItemMoved ( ListChangedEventArgs e ) : void	Handle ItemMoved event
HandleListChangedMetadataChanged ( ListChangedEventArgs e ) : void	Handle PropertyDescriptor* events
HandleListChangedReset ( ListChangedEventArgs e ) : void	Handle the Reset event
HandleListViewBindingContextChanged ( object sender, EventArgs e ) : void	Handle a change to the BindingContext of our ListView.
HandleListViewFreezing ( object sender, BrightIdeasSoftware.FreezeEventArgs e ) : void	Handle the frozenness of our ListView changing.
HandleListViewSelectedIndexChanged ( object sender, EventArgs e ) : void	Handle the selection changing in our ListView. We need to tell our currency manager about the new position.
InitializeDataSource ( ) : void	The data source for this control has changed. Reconfigure the control for the new source
RebindDataSource ( ) : void	Our data source has changed. Figure out how to handle the new source
RebindDataSource ( bool forceDataInitialization ) : void	Our data source has changed. Figure out how to handle the new source
SetListContents ( ) : void	Take the contents of the currently bound list and put them into the control
ShouldCreateColumn ( PropertyDescriptor property ) : bool	Decide if a new column should be added to the control to display the given property
UnbindDataSource ( ) : void
UnbindListView ( ObjectListView olv ) : void

This method will create columns if there is not already a column displaying that property.

protected CreateColumnsFromSource ( ) : void
Результат	void

CreateMissingAspectGettersAndPutters() защищенный Метод

Generate aspect getters and putters for any columns that are missing them (and for which we have enough information to actually generate a getter)

CurrencyManagerListChanged() защищенный Метод

CurrencyManager ListChanged event handler. Deals with fine-grained changes to list items.

It's actually difficult to deal with these changes in a fine-grained manner. If our listview is grouped, then any change may make a new group appear or an old group disappear. It is rarely enough to simply update the affected row.
