Note: This event is new in the .NET Framework version 2.0.
Occurs when a menu item in a
Menu control is bound to data.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Syntax
Visual Basic (Declaration)
Public Event MenuItemDataBound As MenuEventHandler
Dim instance As Menu
Dim handler As MenuEventHandler
AddHandler instance.MenuItemDataBound, handler
public event MenuEventHandler MenuItemDataBound
public:
event MenuEventHandler^ MenuItemDataBound {
void add (MenuEventHandler^ value);
void remove (MenuEventHandler^ value);
}
/** @event */
public void add_MenuItemDataBound (MenuEventHandler value)
/** @event */
public void remove_MenuItemDataBound (MenuEventHandler value)
JScript supports the use of events, but not the declaration of new ones.
Remarks
The MenuItemDataBound event is raised when a menu item is bound to data in a Menu control. This allows you to provide an event handler that performs a custom routine, such as adding custom content or modifying a menu item before it is rendered, whenever this event occurs.
A MenuEventArgs object is passed to the event handler, which allows you to access the properties of the menu item that raised the event.
For more information about handling events, see Consuming Events.
Example
The following code example demonstrates how to create an event handler for the MenuItemDataBound event that modifies the text of the Home menu item before it is displayed in a Menu control.
<%@ Page Language="VB" %>
<script runat="server">
Sub NavigationMenu_MenuItemDataBound(ByVal sender As Object, ByVal e As MenuEventArgs)
' Modify the text of the Home menu item by
' adding parenthesis around the text.
If e.Item.Text = "Home" Then
e.Item.Text = "(" & e.Item.Text & ")"
End If
End Sub
</script>

<body>
<form runat="server">
