SmartNavigation

Synopsis

Boolean = Page.SmartNavigation
Page.SmartNavigation = Boolean

Returns or sets a Boolean indicating whether the SmartNavigation feature is turned on. The SmartNavigation feature, which is compatible only with Internet Explorer, uses <iframe> elements to allow only portions of the page to be refreshed when the page is posted back. This can help eliminate the annoying visual flicker associated with postbacks.

Parameters

Boolean

A Boolean value that indicates whether or not SmartNavigation is enabled.

         Sub Page_Load(  )
            Message.Text = "This Label will change."
            Message2.Text = "This Label will not change."
         End Sub
         Sub UpdateLabel(Sender As Object, e As EventArgs)
            Message.Text = "This Label has changed."
         End Sub
      </script>
   </head>
<body>
   <form runat="server">
      <asp:label id="Message" runat="server"/>
      <asp:button id="update" 
         onClick="UpdateLabel"
         text="Click to update label text"

   </form>
   <asp:label id="Message2" runat="server"/>
