I have created an automated report system, that uses a formula to run a crystal report file.
When the report file has a SQL view linked to it, the formula sent is just the criteria that the report should show Ie "{PAY_TRANS_REPORT_DATA_VIEW.PAYDT} IN #startDT# to #endDT#"
However, I have some reports that use stored procedures which have parameters required.
My question, is how do I send these parameter values to the report?
Thanks.
Let the name of the report you want to pass a parameter is Report1 then you can pass your parameter, parameter1, to your report with the following way:
ReportClass.SetParameterValue("parameter1",parameter1);
The ReportClass is the class that's associated with the Report1.

I am facing an issue in the report in which my written xml is not bound into the report. The result is blank report.
Any help?
Links where i got the idea from:
https://gallery.technet.microsoft.com/scriptcenter/Dynamic-RDLC-Generator-6237aa44
Generating report from rdlc xml string
It Worked!, it was something related to parameters!!
parameters[0] = new ReportParameter("FeeColumnVisibility",
withFee.ToString());
System.Array.Resize(ref parameters, 4);
In which the Parameters are needed to declare whether i need some specific columns or not
The WithFee is a boolean variable that is also something related to my work
I have crystal report reading data from procedure1 take courseID as parameter, I insert sub report in that report reading data from procedure2 also take courseID as a parameter, when procedure2 return result the main report work fine and both main and sub report display but when procedure2 return no result the main report show me "missing parameter value" error
any help???
Set your parameter to optional in the parameter settings.
Right Click the desired parameter in the main report choose Edit... and toggle the Optional Prompt to true.
I hope this helps.
My report gets data from a stored procedure. Two of the six parameters are dates (toDate and fromDate.) I integrate the report with C# Winforms and I pass the parameters through code the code with:
reportDocument.setParamterValue(0,paramValue);
The report works fine but does not render data despite showing the column header properly. When I refresh the report, it pops up the parameter window again. When I enter the parameters through that window the data shows, including column headers. But it doesn't work when I pass parameters through code.
How can I resolve this?
It looks like this:
CRPT.SetParameterValue("smonth", Servercls.month);
See this link for more info.
I suggest first of all call procedure in c# environment and save result in datatable and then send datatable to crystal report.
I found the error.
First it was not working with setting parameters through indexing. so i set the parameters through name as reds suggested.
second i was missing the parameters binding with report viewer object.
so i added the following line and it worked
crystalReportViewer.ParameterField.addRange(reportDocument.ParameterFields);
Thanks for the answers guys.
I have a crystal report written in CR for VS2010. The report will produce invoices over a range of either invoice numbers or dates. To that end, the report has 4 parameters (fromInvoice, toInvoice, fromDate & toDate). The stored procedure can handle nulls for any of the fields so it can receive
If I run the report with just invoice numbers the reports pagination works fine, same for invoice numbers and dates combined (and the parameters persist across the pagination). But if I search with just the from and to dates then it returns the correct number of pages (as visible in the web viewer) but when I click next then it seems to lose the date parameters and displays all the invoices produced, ever.
Any idea where I'm going wrong? why would a date parameter not persist when other parameters have?
the report is called from the same underlying c# page.
fixed. viewer needed viewstatemode='enabled' adding to the aspx page
I'm using C#.NET to programmatically load a Crystal Report document (which gets its data from a database) and then export it as a PDF.
I'm stuck trying to read a fields (abc123) value from within the report (I want to use it in the filename). I don't mind where this field is in the crystal report; and it will not be repeated, but it needs to be a field in the report.
My code so far:
// Setup
ReportDocument reportTemplate = new ReportDocument();
reportTemplate.Load(textBox1.Text);
reportTemplate.Refresh();
reportTemplate.ReadRecords();
// Load the current reports name from the report summary information
String ReportName = reportTemplate.SummaryInfo.ReportTitle.ToString();
// Load the current reports "abc123" field from the report
// ????
// Export the report as PDF
reportTemplate.Export();
I've tried:
// Load the current reports "abc123" field from the report
String abcField = ((TextObject)rpt.Section2.ReportObjects["abc123"]).Text
String abcField = reportTemplate.ReportDefinition.ReportObjects["abc123"].ToString();
String abcField = reportTemplate.Rows.ReportDocument.ReportDefinition.ReportObjects["abc123"];
Without luck. Can anyone give some pointers? I can preview the report using crystalReportView1 object and the field is populated there.
Unfortunately you will not be able to pull a calculated field value from code behind. The calculated field value is not available until after the report engine takes over and does the rendering. You can access/modify formula definitions before the report is rendered but have no access to the actual value calculated from code behind. Even if you add a blank subreport and add a parameter to it from the main report for the field value you are trying to access it will not have a value before the reports engine renders it. You should definitely look for a way to pull it from the data you are binding the report with.
