c# - 在 stimulsoft 报告中处理关系时出现错误

Question

错误是:附加信息:父数据源“EmpDetails”和子数据源“SalaryDetails”不在一个数据集中，并且不能用于关系“EmpSal”!您可以使用 CacheAllData 的属性报告将此数据源缓存到一个数据集。

 public class Employeedetails
 {
    public string EmployeeName { get; set; }
    public string JoiningDate { get; set; }
    public string Designation { get; set; }
    public string Department { get; set; }
    public string Nationality { get; set; }
    public string Status { get; set; }
    public string ContractType { get; set; }
    public string LastWorkingDate { get; set; }
    public string LengthofService { get; set; }
    public string ReasonforExit { get; set; }
    public int EmployeeId { get; set; }
}

public class EmployeeSalaryDetails
{
    public int EmployeeId { get; set; }
    public string AllowanceName { get; set; }
    public string Amount { get; set; }
} 

report.CacheAllData = true;                      
report.Load(Server.MapPath("~/Content/Reports/ReportTemplates/FinalSettlementReport - Copy.mrt"));
report.RegData("EmpDetails", EmployeeDetailsList);
report.RegData("SalaryDetails", EmployeeSalaryList);

this is report designin in stimulsoft

Answer 1

report.Load(Server.MapPath("~/Content/Reports/ReportTemplates/FinalSettlementReport - Copy.mrt"));
                report.RegData("EmpDetails", EmployeeDetailsList);
                report.RegData("SalaryDetails", EmployeeSalaryList);                
                report.RegBusinessObject("SchoolInfoModel", schoolInfo);
                report.CacheAllData = true;

改变 report.CacheAllData = true 的位置后；加载报告完成后，它可以正常工作。'
