Good afternoon. I have a datagridview that populates through a select database, and in that datagrideviwer I have a column with a chekbox, to select the line I want to send to the impression, only this is happening the next, when I select the line, and I send printing it is not obeying the selection and prints all lines.

Below, the code in which I populate the datagridview:

private void ListaGrid()
        {
            SqlCommand comando;

            StringBuilder Query = new StringBuilder();
            Query.Append(" SELECT                                                                            ");
            Query.Append("   CAST(0 AS bit) AS SELECIONAR                                                    ");
            Query.Append("   ,SC.C2_NUM AS GUIA                                                              ");
            Query.Append("   ,SB.B1_DESC AS PRODUTO                                                          ");
            Query.Append("   ,SC.C2_XNPAIS [PAÍS ORIGEM]                                                     ");
            Query.Append("   ,CONVERT(VARCHAR(10), CAST( SC.C2_XDTFAB AS DATE),103) AS [DT. FABRICAÇÃO]      ");
            Query.Append("   ,CONVERT(VARCHAR(10), CAST( SC.C2_XDTVALI AS DATE),103) AS [DT. VALIDADE]       ");
            Query.Append("   ,SC.C2_XLOTEF AS [LT. FABRICANTE]                                               ");
            Query.Append("   ,SC.C2_XLOTE AS [LT. INTERNO]                                                   ");
            Query.Append("   ,SB.B1_XDCB AS DCB                                                              ");
            Query.Append("   ,SB.B1_XCAS AS CAS                                                              ");
            Query.Append("   ,CONVERT(VARCHAR(10),CAST(SB.B1_PESO AS NUMERIC(15, 3))) + SB.B1_XSEGUM AS PESO ");
            Query.Append("   ,SC.C2_XNOMFA AS FABRICANTE ");
            Query.Append("   ,CB.CB0_CODETI AS [COD. BARRAS] ");
            Query.Append("   FROM SC2020 AS SC ");
            Query.Append("   INNER JOIN SB1020 AS SB WITH (NOLOCK) ON SB.B1_COD = SC.C2_PRODUTO ");
            Query.Append("   INNER JOIN CB0020 AS CB WITH (NOLOCK) ON CB.CB0_LOTE = SC.C2_XLOTE ");
            Query.Append("   WHERE C2_NUM = @C2_NUM ");

            comando = conex.CreateCommand();
            comando.CommandText = Query.ToString();

            comando.Parameters.Add("@C2_NUM", SqlDbType.VarChar).Value = txtGuiaFrac.Text.Trim();

            try
            {
                SqlDataAdapter dados = new SqlDataAdapter(comando);
                DataTable dtLista = new DataTable();
                dados.Fill(dtLista);

                DGW_EtqFracionamento.DataSource = dtLista;

                DGW_EtqFracionamento.Columns["GUIA"].ReadOnly = true;

            catch
            {
                MessageBox.Show("Não existem dados a serem encontrados");
            }
        }

Below, the code for the print button.

private void btnImprimir_Click(object sender, EventArgs e)
        {
            DataTable tableGrid = (DataTable)DGW_EtqFracionamento.DataSource;
            DataTable tableRelatorio = null;

            var filter = from DataRow row in tableGrid.Rows
                         where Convert.ToBoolean(row["SELECIONAR"])
                         select row;
            if (filter.Count() > 0)
            {
                tableRelatorio = filter.CopyToDataTable();
                if (caixa_selecao.ShowDialog() == DialogResult.Cancel)
                    return;
                else
                    EtqFraciona.PrinterSettings = caixa_selecao.PrinterSettings;
                EtqFraciona.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("Etiqueta", 420, 200);
                etqfrac();
            }
            else
            {

Danilo thanks for the attention, but also did not work, I think the problem is in the part that I mount the label and send to the printer, I think in this while here down.

private void etqfrac () { conex.Open (); SqlCommand command;

        StringBuilder Query = new StringBuilder();
        Query.Append("   SELECT                                                                          ");
        Query.Append("   CAST(0 AS bit) AS SELECIONAR                                                    ");

Is it possible to include dynamic libraries in static? Specify command for the CMD to open

I think you're putting this code in the wrong event or method.

Do this:

    private void btnImprimir_Click(object sender, EventArgs e)
    {
        printDocument1.Print();
    }

In the PrintDocument1_PrintPage method do this:

  PrintDocument1_PrintPage(object sender, PrintPageEventArgs e)
  {
        DataTable tableGrid = (DataTable)DGW_EtqFracionamento.DataSource;
        DataTable tableRelatorio = null;

        var filter = from DataRow row in tableGrid.Rows
                     where Convert.ToBoolean(row["SELECIONAR"])
                     select row;
        if (filter.Count() > 0)
        {
            tableRelatorio = filter.CopyToDataTable();
            if (caixa_selecao.ShowDialog() == DialogResult.Cancel)
                return;
            else
                EtqFraciona.PrinterSettings = caixa_selecao.PrinterSettings;

            EtqFraciona.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("Etiqueta", 420, 200);
            etqfrac();
        }
        else
        {
            MessageBox.Show("Selecione pelo menos um registro para impressão!", "Atenção", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            return;
        }
    }
