Question

我试图用参数选择来加载报告。我手动做了表格和报告的所有必要内容。我没有得到报告上的值。报告将显示为空白。这是我在后面所写的代码。

using CrystalDecisions.CrystalReports.Engine;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnSearch_Click(object sender, EventArgs e)
    {
        ReportDocument reportdocument = new ReportDocument();
reportdocument.Load(Server.MapPath("MR1.rpt"));
//reportdocument.SetDatabaseLogon("", "", "SureshDasari", "MySampleDB");
reportdocument.SetParameterValue("Material_Code", txtMC.Text);
CrystalReportViewer1.ReportSource = reportdocument;
    }
}

请纠正我,请纠正我

您已经评论了登录参数。您是否将“ 启用数据库登录提示” 设置为真?

尝试装入全部路径负载 :

reportDocument.Load(@"FullPathOfYourReport");
