将参数传递给水晶报告??? [英] Passing Parameters to a crystal report???

问题描述

我想知道如何将paameters传递到水晶报告中我丢失的东西。

<我建立了我的报告，并且我给了我想要传递给它们的字段的名称，然后我写了这些代码行，假设传递参数但我得到了一个例外，告诉我索引无效??? / p>

任何人都可以帮助我吗？我将非常感谢您的努力

DataDefinition DataDef = LeavesCR.DataDefinition;

ParameterFieldDefinitions Defs = DataDef.ParameterFields;

ParameterDiscreteValue paramDiscreteValue;

ParameterValues < font size = 2> currentValue;

ParameterFields fields;

currentValue = new ParameterValues （）;

paramDiscreteValue = new ParameterDiscreteValue （）;

fields = new Paramete rFields （）;

paramDiscreteValue.Value =" Value";

currentValue.Add（paramDiscreteValue ）;

Defs [ " Parm" ]。ApplyCurrentValues（currentValue） ）;

解决方案

我写了以下代码，希望它能解决你的问题

rptDetail myDataReport = new rptDetail（）;

ParameterFields Fields = new ParameterFields（）;

ParameterDiscreteValue paramValue = new ParameterDiscreteValue（）;

ParameterField paramField1 = new ParameterField（）;

paramField1.ParameterFieldName = " PrameterName" ;

paramValue.Value = " Hello There" ;

paramField1.CurrentValues.Add（paramValue）;

Fields.Add（paramField1）;

myDataReport.SetParameterValue（ " PrameterName" ，paramValue）;

crystalReportViewer1.ParameterFieldInfo = Fields;

crystalReportViewer1.ReportSource = myDataReport;

Hi, I Wanna know how to pass paameters to crystal report where I have a missing something.

I built my report and I gave names to the fields that I want to pass to them values, then I write these lines of code that suppose pass parameters but I got an excepetion that told me that index is not valid ???

Can Anyone Help me? I will appreciate ur efforts

DataDefinition DataDef = LeavesCR.DataDefinition;

ParameterFieldDefinitions Defs = DataDef.ParameterFields;

ParameterDiscreteValue paramDiscreteValue;

ParameterValues currentValue;

ParameterFields fields;

currentValue = new ParameterValues();

paramDiscreteValue = new ParameterDiscreteValue();

fields = new ParameterFields();

paramDiscreteValue.Value = "Value";

currentValue.Add(paramDiscreteValue);

Defs["Parm"].ApplyCurrentValues(currentValue);

解决方案

I have written the following code, hope it solve your problem

 

rptDetail myDataReport = new rptDetail();

ParameterFields Fields = new ParameterFields();

ParameterDiscreteValue paramValue = new ParameterDiscreteValue();

ParameterField paramField1 = new ParameterField();

paramField1.ParameterFieldName = "PrameterName";

paramValue.Value = "Hello There";

 

 

paramField1.CurrentValues.Add(paramValue);

Fields.Add(paramField1);

 

myDataReport.SetParameterValue("PrameterName", paramValue);

 

crystalReportViewer1.ParameterFieldInfo = Fields;

crystalReportViewer1.ReportSource = myDataReport;
