ListItemsCollectionEditor Class
Assembly: System.Design (in system.design.dll)
The ListItemsCollectionEditor class provides a user interface for editing the ListItem elements of the ListItemCollection object within a control that is derived from the ListControl or a similar control.
The ListItemsCollectionEditor is invoked by selecting the ellipsis (…) button on the ListItems property in the Properties grid of the visual designer.
The CanSelectMultipleInstances method always returns false to indicate that only one object can be selected at a time in the editor. The HelpTopic property returns the name of the Help topic that the editor displays.
The following code example shows how to use the EditorAttribute class to associate the ListItemsCollectionEditor class and the UITypeEditor class (the collection editor's base class) with a custom ListItems property.
