I want to show that as button into a single crystal report, how?

I have grid1 and grid2 showing data on buttonclick and in the same way I need to show this in crystal report.

推荐答案

您可以将2个数据集存储在2个会话中， ;检查然后分配给报告，仅此而已.

You can store the 2 datasets in 2 sessions & check then assign to report, That''s all.

protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
    ReportDocument myReportDocument = new ReportDocument();
    myReportDocument.Load(Server.MapPath("\\test.rpt");

    if(Session["DataSet1"] != null)
        {
            DataSet rptDs1 = (DataSet)Session["DataSet1"];
            myReportDocument.SetDataSource(rptDs1);
        }
        else if (Session["DataSet2"] != null)
        {
            DataSet rptDs2 = (DataSet)Session["DataSet2"];
            myReportDocument.SetDataSource(rptDs2);
        }
        CrystalReportViewer1.ReportSource = myReportDocument;
        CrystalReportViewer1.DataBind();
        CrystalReportViewer1.EnableDrillDown = true;
}

，希望它能解决您的问题.
