How avoid the cache of Textbox

As the other answerer said, disable AutoCompleteType property of the textbox.

<asp:TextBox ID="TextBox1" runat="server" AutoCompleteType="Disabled"></asp:TextBox>

But this would not work in Mozilla Firefox. The best option would be to write a JavaScript onFocus of the text box to disable the autocomplete behaviour.

<asp:TextBox ID="TextBox1" runat="server" AutoCompleteType="Disabled" onfocus="disableautocompletion(this.id);" ></asp:TextBox>

Javascript:

function disableautocompletion(id){ 
    var passwordControl = document.getElementById(id);
    passwordControl.setAttribute("autocomplete", "off");
}

Hope this helps! :thumbsup:

Hello AngelLoose,

Set this to off in your text box definition---autocomplete="off".And i've seen that it is not visible in intellisense but works pretty well in both IE and firefox for asp:Textbox.try it,it works...

As I getting your answer you want to remove the cache of control whenever page is load if so,
Use this code on Page Load event

Response.Cache.SetNoStore();

Use !IsPostBack
Example

protected void Page_Load(object sender, EventArgs e){
if (!IsPostBack)
        {
           txtName.text = "";
           txtDes.text = "";
        }
}
