Disable Cut, Copy and Paste function for textbox using jQuery

All you need is to bind cut, copy and paste function to Textbox and stop the current action. See below code.

$(document).ready(function(){
  $('#txtInput').live("cut copy paste",function(e) {
      e.preventDefault();
  });
});

You can also use bind function to bind these events. Read more about bind() method here.

$(document).ready(function(){
  $('#txtInput').bind("cut copy paste",function(e) {
      e.preventDefault();
  });
});

Detecting Refresh or Postback in ASP.NET

One of the biggest challenges for web developers is the resubmission of form data or the refresh of a form to post information to a database. This happens when the user, for whatever reason, resubmits or refreshes the form, which has the potential to cause chaos with duplicated database insertions or repeated email submissions.
In this article I Will show you how to define page is postback or refresh after postback.
Here my simple code

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Session["PostID"] = "1001";
            ViewState["PostID"] = Session["PostID"].ToString();
            Response.Write("First Load");
        }
        else
        {
            if (ViewState["PostID"].ToString() == Session["PostID"].ToString())
            {
                
                Session["PostID"] = (Convert.ToInt16(Session["PostID"]) + 1).ToString();

                ViewState["PostID"] = Session["PostID"].ToString();
                Response.Write("Postback");

            }
            else
            {
                ViewState["PostID"] = Session["PostID"].ToString();
                Response.Write("refreshed");

            }
        }
    }

Thanks
