我是水晶报告的新手.我按照这个链接
Crystal Report with SQL Stored Procedure Parameter and Visual Studio设计了水晶报告
实际上我需要将不同的ID(SP的输入值)传递给我与Crystal报表连接的SP.
实际上我需要将不同的ID(SP的输入值)传递给我与Crystal报表连接的SP.
这是我将ID传递给水晶报告的代码：
protected void Button1_Click(object sender,EventArgs e)
{
string QuotationID = ViewState["QUOTATION_ID"].ToString();
ReportDocument reportDocument = new ReportDocument();
ParameterField paramField = new ParameterField();
ParameterFields paramFields = new ParameterFields();
ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
paramField.Name = "@id";
paramDiscreteValue.Value = QuotationID;
paramField.CurrentValues.Add(paramDiscreteValue);
paramFields.Add(paramField);
paramFields.Add(paramField);
CrystalReportViewer1.ParameterFieldInfo = paramFields;
string reportPath = Server.MapPath("~/CrystalReport.rpt");
reportDocument.Load(reportPath);
CrystalReportViewer1.ReportSource = reportDocument;
}
但是当我点击按钮时它会询问ID …
解决方法
要在水晶上设置参数,我总是这样做：
ReportDocument reportDocument = new ReportDocument();
reportDocument.Load(reportPath);
reportDocument.SetParameterValue("@id",QuotationID);
如果您想将报告转换为pdf：
var exportOptions = reportDocument.ExportOptions;
exportOptions.ExportDestinationType = ExportDestinationType.NoDestination;
exportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
var req = new ExportRequestContext {ExportInfo = exportOptions};
var stream = reportDocument.FormatEngine.ExportToStream(req);
