将参数传递给RDLC报告时出错 [英] Error Passing Parameter to RDLC Report

问题描述

大家好。

我有一个带有文本框的表单和一个打开包含RDLC报告的表单的按钮。有没有办法将文本框中输入的值传递给RDLC报告以便使用它计算？



非常感谢任何帮助。



表单加载代码

this.reportViewer1.LocalReport.ReportEmbeddedResource =TestReport.Report1.rdlc;

ReportParameter rp = new ReportParameter（content，this.textBox1.Text）;

this.reportViewer1.LocalReport.SetParameters（new ReportParameter [] {rp}）;

this.reportViewer1.RefreshReport（）;





----- -------------------------------------------------- --------

VS2010说

无法找到类型或命名空间名称''ReportParameter'（你是否缺少using指令或程序集）参考？）

请帮忙.....
提前感谢.... !!

解决方案

正如此处提到的那样 [ ^ ]，对于RDLC：

< pre lang =cs> ReportViewer1.LocalReport.ReportPath = 〜/ Report1.rdlc;
ReportParameter [] Parameters = new ReportParameter [ 1 ];

参数[ 0 ] = new ReportParameter（ LastName，Convert.ToString（LastNameDropDownList.SelectedValue））;
ReportViewer1.LocalReport.SetParameters（Parameters）;

Hello to all.
I have a form with a textbox and a button that opens a form containing an RDLC report. Is there a way to pass the value entered in the text box to the RDLC report in order to use it calculations?

Thanks a lot for any kind help.

Form Load code
this.reportViewer1.LocalReport.ReportEmbeddedResource = "TestReport.Report1.rdlc";
ReportParameter rp = new ReportParameter("content", this.textBox1.Text);
this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rp });
this.reportViewer1.RefreshReport();


---------------------------------------------------------------
VS2010 says
The type or namespace name ''ReportParameter'' could not be found (are you missing a using directive or an assembly reference?)

---------------------------------------------------------------
Please Help.....
thanks in advance....!!

解决方案

As mentioned here[^], for RDLC:

ReportViewer1.LocalReport.ReportPath  ="~/Report1.rdlc";
ReportParameter[] Parameters = new ReportParameter[1];

Parameters[0] = new ReportParameter("LastName", Convert.ToString(LastNameDropDownList.SelectedValue));
ReportViewer1.LocalReport.SetParameters(Parameters);
