从代码打印报告 (ReportViewer)（无预览）

  • 772

protected void Page_Load(object sender, EventArgs e)
{
//aqui muestro mi reporte en la pagina

 if (!Page.IsPostBack)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["cn"].ToString()))
{
SqlCommand cmd = new SqlCommand("SELECT * from tabla where Cod_user='" + Session["Cod_user"] + "'", con);
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
DataTable t = new DataTable();
da.Fill(t);
ReportDataSource datasource = new ReportDataSource("DataSet1", t);           ReportViewer1.LocalReport.DataSources.Add(datasource);
ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reportes/Report1.rdlc"); 
ReportViewer1.LocalReport.Refresh();
}
}
}
}

//boton imprimir
protected void Imprimir_Click(object sender, EventArgs e)
{

}

我有一份带有发票报告查看器的报告，它为我带来数据库中的数据，我希望能够在不需要使用预览的情况下打印它，也就是说，使用单独的按钮通过编程来完成，也就是说，不是使用默认具有reportviewer 的那个。

我希望你能帮助我谢谢

使用 JQUEY 的解决方案

<!--script para imprimir-->
<script type="text/javascript">
	function Print() {
		var report = document.getElementById("<%=ReportViewer1.ClientID%>");
	var div = report.getElementsByTagName("DIV");

	var reportContents;
	for (var i = 0; i < div.length; i++) {
		if (div[i].id.indexOf("VisibleReportContent") !== -1) {
			reportContents = div[i].innerHTML;
			break;
		}
	}
	var frame1 = document.createElement('iframe');
	frame1.name = "frame1";
	frame1.style.position = "absolute";
	frame1.style.top = "-1000000px";
	document.body.appendChild(frame1);
	var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document :frame1.contentDocument;
	frameDoc.document.open();
	frameDoc.document.write(reportContents);
	frameDoc.document.write("<style> @page { size: portrait; } .head { display: none; }></style>");
	frameDoc.document.close();
	setTimeout(function () {
		window.frames["frame1"].focus();
		window.frames["frame1"].print();
		document.body.removeChild(frame1);
	}, 500);   
	}
	
</script>

        //boton imprimir
    protected void Imprimir_Click(object sender, EventArgs e)
    {
        ReportDocument rd = new ReportDocument();

        //cargas el contendido del reporte.

        PrintDialog prt = new PrintDialog();
        rd.PrintOptions.PrinterName = prt.PrinterSettings.PrinterName; 
        rd.PrintToPrinter(copies, true, 1, 1000); 
    }
