rdlc多值参数如何赋值？
我做了个rdlc的报表，自己定义了一个报表参数选成多值，如何通过写程序代码给这个多值报表参数赋值呢？ --------------------编程问答-------------------- 有做过的吗 --------------------编程问答-------------------- --------------------编程问答-------------------- 参考 --------------------编程问答-------------------- 根据用户所选的参数，把数据值传到SQL语句中即可.下面是RequestReport方法的源码DataTable RequestReport(DateTime dtFrom, DateTime dtTo, string pMaterial, string pDept, string pRequester, string pIPRStatus) {
string MySQL = Purchase;
string whDate = " RequestDate BETWEEN '{0}' AND '{1}' ";
MySQL = MySQL + string.Format(whDate, dtFrom, dtTo);
string whMaterial = " AND MaterialCode='{0}' ";
if (pMaterial != "ALL")
{
MySQL = MySQL + string.Format(whMaterial, pMaterial);
}
string whDept = " AND RequestDepartment='{0}' ";
MySQL = MySQL + string.Format(whDept, pDept);
string whRequester=" AND Requester='{0}' ";
if(pRequester!="ALL")
MySQL = MySQL + string.Format(whRequester, pRequester);
string whIPRStatus = " AND IPRStatus={0} ";
if (pIPRStatus != "ALL")
{
MySQL = MySQL + string.Format(whIPRStatus, pIPRStatus);
}
IDataProvider privider = DataProvider.CreateDataProvider();
DataSet ds = privider.RetriveDataSet(MySQL);
if (ds != null && ds.Tables.Count > 0)
return ds.Tables[0];
else
return null;
}
const string Purchase="SELECT SerialNO,LedgerAcc,CostCenter,Requester,"+
" RequestDate,RequestDepartment,MaterialCode, " +
" Brand,Specifications,Unit,Quantity,Usage, "+
" ExpectedDeliveryDate,Currency "+
" ,Quotation1Supplier,Quotation1UnitPrice,Quotation1Amount, "+
" Quotation2Supplier,Quotation2UnitPrice,Quotation2Amount, "+
" Quotation3Supplier, Quotation3UnitPrice, Quotation3Amount, "+
" ProposedQuotationSupplier, ProposedQuotationUnitPrice, "+
" ProposedQuotationAmount,QuotationRemarks ,IPRStatus,QtyTo, UnitPriceTo FROM IPR WHERE "; --------------------编程问答-------------------- 我问的是，rdlc报表中自定义报表参数，把参数的多值属性选中以后，这个多值的参数如何通过asp.net页面传值
--------------------编程问答--------------------
参数定义如上图
后台代码：
List<ReportParameter> parameters = new List<ReportParameter>(ReportViewer1.LocalReport.GetParameters().Count);
parameters.Add(new ReportParameter("报表中定义的参数名称", new string[]{"参数值1","参数值2"}));
ReportViewer1.LocalReport.SetParameters(parameters);
补充：.NET技术 , ASP.NET
