protected void Button1_Click(object sender, EventArgs e)
{
emp.empid = int.Parse(TextBox1.Text);
emp.empname = TextBox2.Text;
emp.empdesig = TextBox3.Text;
emp.empsalary = int.Parse(TextBox4.Text);
ae.employees.AddObject(emp);
ae.SaveChanges();
Response.Write("data inserted....");
GridView1.DataSource = ae.employees;
GridView1.DataBind();
