What I have tried:

public void cmbdisp()
{
    SqlConnection con = new SqlConnection(ConnectionString);
    cmboSelEmp.Items.Clear();
    con.Open();
    SqlCommand cmd = new SqlCommand();
    cmd = con.CreateCommand();
    cmd.CommandText = "Select * from add_employee";
    cmd.ExecuteNonQuery();
    DataTable dt = new DataTable();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    da.Fill(dt);
    foreach (DataRow dr in dt.Rows)
    {
        cmboSelEmp.Items.Add(dr["name"].ToString());
        cmboSelEmp.SelectedValuePath = (dr["name"].ToString());
        cmboSelEmp.SelectedValuePath = (dr["eid"].ToString());
    }

}

The trouble with loops is, when you assign a value to a single variable inside one after the loop you only have a single value in it - the last one:
C#
foreach (int x in Enumerable.Range(0, 9))
   {
   lastvalue = x;
   }

So when your do the same thing with a datatable, the only result you get is always the last element in the table ...
