SubMenuStyleCollectionEditor Class

Provides a component editor for the SubMenuStyleCollection object in the associated Menu control.

Namespace:  System.Web.UI.Design.WebControls
Assembly:  System.Design (in System.Design.dll)

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public class SubMenuStyleCollectionEditor : CollectionEditor

The SubMenuStyleCollectionEditor class provides a user interface for editing the SubMenuStyle elements of the SubMenuStyleCollection object in the associated Menu control at design time, under the control of the MenuDesigner object.

There is a SubMenuStyleCollection associated with the LevelSubMenuStyles property of the Menu control. The SubMenuStyleCollection object is used to apply styles to static submenu items that depend on their level (nesting depth) in the menu structure.

The SubMenuStyleCollectionEditor is invoked, for example, by selecting the ellipsis button () on the LevelSubMenuStyles row 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 CreateCollectionForm method creates a new form to display and edit the SubMenuStyleCollection.

The CreateInstance method creates a new instance of the specified collection item type. The CreateNewItemTypes method returns an array of types that the editor can create.

The following code example shows how to use the EditorAttribute attribute to associate the SubMenuStyleCollectionEditor and UITypeEditor (the collection editor base class) classes with a property in a custom control, derived from the WebControl class, that gets and sets a SubMenuStyleCollection collection.

private SubMenuStyleCollection subMenuStyles;

// Associate the SubMenuStyleCollectionEditor with the  
// LevelSubMenuStyles. 
[Editor(typeof(System.Web.UI.Design.WebControls.
    SubMenuStyleCollectionEditor),
    typeof(UITypeEditor))]
public SubMenuStyleCollection LevelSubMenuStyles
{
    get { return subMenuStyles; }
    set { subMenuStyles = value; }
} // LevelSubMenuStyles
