We can dissable this autocomplete in two label.
  1. In browser Label

  2. In Coading Label
  • Using AutoCompleteType="Disabled" of a textbox.
  • Using autocomplete="off" of a textbox.
  • Setting form autocomplete="off".
  • setting textbox attribe.
  • Using Jquery.

In browser Label

Here i am going to show how to dissable in browser Label.

Go to the Browser Setting.



Go to the Advance Setting and Check for Passwords and Forms.
Unckeck the the two checkbox.

 
Then Reset all changes.



After that open that open the Login page and type that no auto suggesation will found. So in this way we can dissable the autocomplete in browser label.
In Coading Label
By making AutoCompleteType="Disabled",
  1. <asp:TextBox runat="server" ID="txt_userid" AutoCompleteType="Disabled"></asp:TextBox>  
By setting autocomplete="off",
  1. <asp:TextBox runat="server" ID="txt_userid" autocomplete="off"></asp:TextBox>  
By Setting Form autocomplete="off",
  1. <form id="form1" runat="server" autocomplete="off">  
  2. //your content  
  3. </form>  
By using code in .cs page,
  1. protected void Page_Load(object sender, EventArgs e)   
  2. {  
  3.     if (!Page.IsPostBack)  
  4.     {  
  5.         txt_userid.Attributes.Add("autocomplete", "off");  
  6.     }  
  7. }  
By Using Jquery 
  1. head runat = "server" >  
  2.     < title > < /title> < script src = "Scripts/jquery-1.6.4.min.js" > < /script> < script type = "text/javascript" >  
  3.     $(document).ready(function()  
  4.     {  
  5.         $('#txt_userid').attr('autocomplete', 'off');  
  6.     });  
  7. //document.getElementById("txt_userid").autocomplete = "off"  
  8. < /script>  
and here is my textbox in <body>,
  1. <asp:TextBox runat="server" ID="txt_userid" ></asp:TextBox>  
By Setting textbox attribute in code,
  1. protected void Page_Load(object sender, EventArgs e)   
  2. {  
  3.     if (!Page.IsPostBack)  
  4.     {  
  5.         txt_userid.Attributes.Add("autocomplete", "off");  
  6.     }  
  7. }  
So in this way we can dissable autocomplete textbox in webform.After dissabling the text will not appear.
