MenuItem Constructor

Initializes a new instance of the MenuItem class without menu text or a value.

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

public MenuItem()

Use this constructor to create a new instance of a MenuItem class without menu text or a value.

NoteNote

When this constructor is used, all properties in the MenuItem object are set to their default values. Be sure to set the properties, as necessary, after creating the object.

This constructor is commonly used when dynamically populating the Items collection of a Menu control or the ChildItems collection of a MenuItem object.

The following example demonstrates how to use this constructor to create a new instance of the MenuItem class. The MenuItem object is then used to dynamically populate the menu items in a Menu control.
