if (con.State == ConnectionState.Closed)
{
con.Open();
}

SqlCommand cmd = new SqlCommand("VAOUCHE_FRM", con);
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.AddWithValue("@activityType", 2);
cmd.Parameters.AddWithValue("@ccodec", Compcls.Gcomp_cd);
SqlDataReader sdr = cmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Clear();
dt.Load(sdr);
cmb.DataSource=dt;
cmb.DisplayMember = dt.Columns["NAME"].ColumnName;
cmb.ValueMember = dt.Columns["AC_CODE"].ColumnName;
cmb.SelectedIndex = 0;
con.Close();

The issue is that the control is not selected. Why are you checking the KeyChar instead of the Keys enum ? Your code seems very sloppy to me, for example, you set the SelectedIndexChanged event twice. You realise that the control will start with a selected index, and this won't fire until it changes ? Is that part of your issue ? If you have to set Visible to true at all, then you should do it before making the control selected, selecting an invisible control won't do anything.
