In the dropdownlist selection changed event

if (DropDownList1.SelectedIndex != 0)
{
string strValue = string.Empty;
SqlConnection con = new SqlConnection("Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;");
SqlCommand cmd = new SqlCommand(" select Empname from Employee where empid='"+ DropDownList1.SelectedValue.ToString()+"'", con);
con.Open();
strValue = (string)cmd.ExecuteScalar();
con.Close();
TextBox1.Text = strValue;
}
