empd.Connection.ConnectionString = ConfigurationManager.ConnectionStrings["DemosConnectionString1"].ConnectionString;
  if (IsPostBack == false)
    {
        display_emp();

Hi

I have seen your code you have small issue in your code. i.e. your grid view is populated on every post back modify your page load event as follows put the following code into the load event

C#

if (IsPostBack == false)
            {
                empd = new Employee_DetailsDataContext();
                empd.Connection.ConnectionString = ConfigurationManager.ConnectionStrings["DemosConnectionString1"].ConnectionString;
                display_emp();
            }
