copied!<p>Set the <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.control.viewstatemode.aspx" rel="nofollow"><code>ViewStateMode</code></a> to <code>Disabled</code> on the page, and omit <code>EnableViewState</code>. You can set it to enabled for some controls (default is <code>Inherit</code>).</p> <p><strong>Edit (sidenote, see comments too):</strong></p> <p>As we discussed in the comment, text boxes keep their value even though ViewState is disabled. This is true, as they are elements of a HTTP POST request. Labels aren't, for instance, as they render to <code>span</code> tags.</p> <p>In the following sample code, there is a label filled with a random number. If you set <code>ViewStateMode</code> to <code>Enabled</code>, the random number from the last request is written to the Debug Output Window. If you set <code>ViewStateMode</code> to <code>Disabled</code>, an empty string is written. The <code>Label</code>'s state is not kept:</p> <pre><code><%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication2.Default" ViewStateMode="Disabled" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <asp:TextBox runat="server" ID="textbox" Text="Default" /> <asp:Label runat="server" ID="randomNumberLabel" /> <asp:Button runat="server" Text="Click Me" /> </form> </body> </html> </code></pre> <p>This is the code behind. Be sure to attach a debugger:</p> <pre><code>namespace WebApplication2 { public partial class Default : System.Web.UI.Page { private readonly static Random rnd = new Random(); protected void Page_Load(object sender, EventArgs e) { if(this.IsPostBack) Debug.WriteLine(this.randomNumberLabel.Text); this.randomNumberLabel.Text = rnd.Next(Int32.MaxValue).ToString(); } } } </code></pre> <p>I hope I managed to clarify the difference.</p>
