问题描述

 private void button4_Click（object sender，EventArgs e）
 {
 Form3 frm = new Form3（）; 
 
 DataSet1 myDataSet = new DataSet1（）; 
 DataTable dataTable = myDataSet._myTable; 
 for（int i = 1; i< = n; i ++）
 {
 
 DataRow drow = dataTable.NewRow（）; 
 if（true）
 {
 
 drow [proid] =0001; 
 drow [proname] =data2; 
 drow [cost] =200; 
 drow [code] =0123; 
 drow [shopname] =商店名称; 
} 
 
 dataTable.Rows.Add（drow）; 
} 
 ReportDataSource datasource = new ReportDataSource（mydata，（DataTable）dataTable）; 
 
 frm.reportViewer1.LocalReport.DataSources.Clear（）; 
 frm.reportViewer1.LocalReport.DataSources.Add（datasource）; 
 frm.reportViewer1.RefreshReport（）;

解决方案

设置报告路径

尝试

{

Pl_Report ObjReport = new Pl_Report（）;

ObjReport.Ind = 1 ;

BlObjslipType.GetReportData（ObjReport）;

ReportViewer2.ProcessingMode = ProcessingMode.Local;

ReportViewer2.LocalReport.ReportPath = Server.MapPath（ Reports / ReportName.rdlc）;

if（ObjReport.ds！= null）

{

ReportDataSource datasource = new ReportDataSource（ DataSet1，ObjReport.ds.Tables [0]）;

ReportViewer2.LocalReport.DataSources.Clear（）;

ReportViewer2.LocalReport.Dat aSources.Add（datasource）;



}

else

{

ReportViewer2.LocalReport.DataSources.Clear（）;

}



}

finally {}

private void button4_Click(object sender, EventArgs e)
        {
			Form3 frm = new Form3();
			
			DataSet1 myDataSet = new DataSet1();
			DataTable dataTable = myDataSet._myTable;
			 for (int i = 1; i <= n; i++)
                {

                    DataRow drow = dataTable.NewRow();
                    if (true)
                    {

                        drow["proid"] = "0001";
                        drow["proname"] = "data2";
                        drow["cost"] = "200";
                        drow["code"] = "0123";
                        drow["shopname"] = "Shop Name";
                    }
                    
                    dataTable.Rows.Add(drow);
                }
			ReportDataSource datasource = new ReportDataSource("mydata", (DataTable)dataTable) ;
            
            frm.reportViewer1.LocalReport.DataSources.Clear();
            frm.reportViewer1.LocalReport.DataSources.Add(datasource);
            frm.reportViewer1.RefreshReport();
			
            frm.Text = "reporting";
            frm.StartPosition = FormStartPosition.CenterScreen;
            frm.ShowDialog();
		}
<pre>

解决方案

Set Report Path
try
{
Pl_Report ObjReport = new Pl_Report();
ObjReport.Ind = 1;
BlObjslipType.GetReportData(ObjReport);
ReportViewer2.ProcessingMode = ProcessingMode.Local;
ReportViewer2.LocalReport.ReportPath = Server.MapPath("Reports/ReportName.rdlc");
if (ObjReport.ds != null)
{
ReportDataSource datasource = new ReportDataSource("DataSet1", ObjReport.ds.Tables[0]);
ReportViewer2.LocalReport.DataSources.Clear();
ReportViewer2.LocalReport.DataSources.Add(datasource);

}
else
{
ReportViewer2.LocalReport.DataSources.Clear();
}

}
finally { }
