Properties

	Name	Description
	AbsoluteItemIdList	Lazy loads and caches the ItemIdList corresponding to the complete path of the ListItem.
	AbsoluteItemIdList_Internal	Simple getter/setter for the AbsoluteItemIdList of this element.
	Checked	This property calls CheckState and returns true only if the item is CheckState.Checked and false if in CheckState.Grayed or CheckState.UnChecked.
	CheckState	If the CheckBoxes property of the ShellListView is true then this property can be used to get or set the check state. If the value that is set changes the item's checkstate, and a ShellControlConnector is assigned to the ShellListView the item is contained in, the SelectionList will be updated accordingly.
	ColumnInfoAvailable	Returns true if the columns have been added as subitems
	Cut	Defines if the item's image should be shown ghosted or not.
	DetailsCompleted	Returns true if item details have already been loaded.
	FullPath	Use to get the full path of this item.
	IsFolder	Gets a value indicating whether this instance is a folder or a file.
	ItemIdListWorkItem	Holds a WorkItem running for this instance.
	OverlayImage	Gets or sets the "OverlayIndex" to use for the element. The index must be known as overlay in the ImageList.
	QueuedCompleteDetailsWorkItem	Holds an already queued workitem to complete the item details, to avoid queuing more than 1 workitem per item.
	RelativeItemIdList	Get the relative PIDL of the current item.
	RelativeItemIdList_Internal	ItemIdList of this item relative to the folder p_Path ItemIdList.
	ShellListView	The same instance as ListView but typed as JamBaseShellListView.
	TooltipWorkItem	Cache for the TooltipWorkItem to make sure only one is running at a time.
	VariantColumnTexts	This array holds the column texts of the item. It`s filled in FillSubitems.

Methods

	Name	Description
	AfterRename	Refreshes the item`s ItemIdLists, text and executes the PathWasRenamed methods
	CompleteDetails	Completes the details of the ShellListBaseItem, given that it's ListView property is set, i.e. the item has been added to the listview.
	CompleteDetails(JamBaseShellListView)	Completes the details of the ShellListBaseItem.
	CompleteDetailsAsync	Completes details asynchronously.
	GetDetails	Loads some values, like the image index into the returned value. Method should not be called in main thread.
	GetVariantValue	Gets the value for the specified column as variant.
	InvertCheckState	This method inverts the CheckState of the ShellListItem instance. If the Item was checked it's state will be set to unchecked. If it was Grayed or UnChecked it will be Checked afterwards. If the Item is not associated (contained) in a ShellListView or the ShellListView has no ShellControlConnector assigned, this method does nothing and returns immediately. Furthermore the ListView needs to have the CheckBoxes property enabled.
	RefreshCheckState	Refreshes the value of the CheckState CheckSate property by starting an asynchronous operation. Calling this method has no effect if the item is not part of a list, or has no ShellControlConnector assigned.
	RefreshGhostedState	Refreshes the ghosted state of the item, e.g. after a SmartRefresh.
	RefreshOverlayImageIndex	Refreshes the overlay image index of the item.
	Reload	Reloads the item. If an ItemIdList is passed it is refreshed and used as new absolute ItemIdList for the item.
	RemoveSubItem	Removes the subitem at the passed postion.
	Rename	Renames the item.
	SetDetails	Applies the passed Details to the item.
	SetImageIndex	This method sets the image index (ImageIndex). It is used in conjunction with BeginInvoke(Delegate, Object).
	SetThumbnailBitmap	Adds the bitmap to the image collection of the imagelist, sets the image index of this item accordingly. Queues another work-item to obtain a real thumbnail later on
