After binding the combobox from database you need to add one extra item at 0th Index as you required.
Try this:

C#

ComboBox1.Items.Insert(0, new ComboBoxItem("-Select-", string.Empty));

Use This

C#

SqlCommand comm = new SqlCommand("select * from EmpDetail");
            SqlDataAdapter adap = new SqlDataAdapter(comm);
            comm.Connection = conn;
            DataSet ds = new DataSet();
            adap.Fill(ds);
            comboBox1.Text = "-select-";
           foreach(DataRow dr1 in ds.Tables[0].Rows)
           {
               comboBox1.Items.Add(dr1["EmpName"].ToString());
           }

Hope this will wok
