MenuItemBinding Constructor

Initializes a new instance of the MenuItemBinding class.

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

public MenuItemBinding()

Use this constructor to create a new instance of the MenuItemBinding class. It is often used when dynamically populating the DataBindings collection of a Menu control.

The following code example demonstrates how to use this constructor to dynamically populate the DataBindings collection of a Menu control. For this example to work correctly, you must copy the sample XML data below to a file named MenuDepth.xml.

<script runat="server">

  void Page_Load(Object sender, EventArgs e)
  {
    if(!IsPostBack)
    {
      // Create a new MenuItemBinding object.
      MenuItemBinding binding = new MenuItemBinding();

      // Set the MenuItemBinding object's properties.
      binding.TextField = "Title";
      binding.ValueField = "Description";
      binding.ImageUrlField = "ImageUrl";
      binding.ToolTipField = "ToolTip";

      // Add the MenuItemBinding object to the 
      // DataBindings collection of the Menu control.
      NavigationMenu.DataBindings.Add(binding);
    }
  }

</script>
