分配离散值后，Crystal Report参数要求输入值 [英] Crystal Report Parameter asking for Value after I've assigned a Distrete Value

问题描述

因此，我正在编写工作正常的水晶报表.

我需要向该报告发送1个离散值.我使用以下代码，然后在其中添加带有参数"名称的参数字段，但是当我运行它时，它显示了查看器面板，当我已经将其指定为"25"并将其拖到报表上的字段中时，该字段要求输入参数"25"应该出现(出于演示目的，请不要使用硬编码变量，而应在代码端动态显示)

So I''m working on a crystal report that works fine.

I need to send 1 Discrete Value to the report. I use the following code and then add a parameter field with the Parameters name in it but when I run it it shows the viewer panel asking for a parameter input when I already specified its "25" and have dragged the field on the report where 25 should appear (please not its a hard-coded variable for demo purposes but will be code-side dynamic)

ParameterField test;
         
test.ParameterFieldName = "TestID";
myDiscreteValue = new ParameterDiscreteValue();
int sTest = 25;
myDiscreteValue.Value = sTest;
test.CurrentValues.Add(myDiscreteValue);

reportParameters.Add(test);

推荐答案

请尝试使用该方法

Please try with that

rptMYReport objRpt = new rptMYReport ();

objRpt.SetDataSource(reportHeader);

objRpt.SetParameterValue("Parameter1", "value1");

objRpt.SetParameterValue("Parameter2", "value2");

在这里，
rptMYReport是我的报告

reportHeader是我的DataTable.

参数1&& Parameter2是您在报表查看器中定义的水晶报表参数.

值1&& value2是您要传递的值.

Here,
rptMYReport is my Report

reportHeader is my DataTable.

Parameter1 && Parameter2 is your crystal report parameter that you define in your report viewr.

value1 && value2 is the value that you want to pass.
