Menu.FindItem Method

Note: This method is new in the .NET Framework version 2.0.

Retrieves the menu item at the specified value path.

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

public MenuItem FindItem (
	string valuePath
)
public MenuItem FindItem (
	String valuePath
)
public function FindItem (
	valuePath : String
) : MenuItem

Parameters

valuePath

The value path to the menu item to retrieve.

Return Value

A MenuItem that represents the menu item at the specified value path.

Use the FindItem method to retrieve a MenuItem object from the Menu control. To retrieve the MenuItem object, you must specify a menu path to the menu item. The menu path is a string of delimited values that form the path from a root menu item to the current menu item. To determine the delimiter character, use the PathSeparator property.

The following code example demonstrates how to use the FindItem method to retrieve a menu item from a Menu control at a specified value path.


<%@ Page Language="C#" %>

<script runat="server">

  void Page_Load(Object sender, EventArgs e)
  {
    // The value path for a menu item is a delimited list
    // of menu text values that form a path from the root 
    // menu item to the current menu item.

    // Declare the value path to the Classical menu item using
    // the delimiter character specified in the PathSeparator
    // property. In this example, the delimiter character is a
    // comma.
    String valuePath = "Home,Music,Classical";
    
    // Use the FindItem method to get the Classical menu item using
    // its value path.
    MenuItem item = NavigationMenu.FindItem(valuePath);
    
    // Indicate whether the menu item was found.
    if (item != null)
    {
      Message.Text = item.Text + " menu item found at depth " + 
        item.Depth.ToString() + ".";
    }
    else
    {
      Message.Text = "Menu item not found.";
    }
  }
  
</script>
