    if (itm_id.Text == "")
        return;

    if (ConnClass.conbase.State == ConnectionState.Open)
    {
        ConnClass.conbase.Close();

    }
    ConnClass.conbase.Open();
    //var idtms = itm_id.Text;
    //int iditm_int = int.Parse(itm_id.Text);
    //int itmid = int.Parse(itm_id.Text);
    string Itm_Show_qry = "select * from ITEM where ITM_ID='" +Strings.Trim(this.itm_id.Text)+"'";
    OleDbDataAdapter itm_da = new OleDbDataAdapter(Itm_Show_qry, ConnClass.conbase);
    DataSet itm_ds = new DataSet();
    itm_da.Fill(itm_ds);
    if (itm_ds == null)
        return;
    if (itm_ds.Tables[0].Rows.Count > 0)
    {


        itm_ar_name.Text = itm_ds.Tables[0].Rows[0]["ITM_NAME"].ToString();


        //itm_barcode.Text = itm_ds.Tables[0].Rows[0]["ITM_CODE"].ToString();

        itm_price.Text = itm_ds.Tables[0].Rows[0]["ITM_PRICE"].ToString();
        barcodelebel.Text = itm_ds.Tables[0].Rows[0]["ITM_CODE"].ToString();
