Hi,

I'm trying to implement the Reset Page Number by Group functionality for a standalone report. I found an example class within the forums. I can see the assembly I've created from the sample code, as well as the function, in the Report Designer(R1 2017) application Edit Expression dialog.

 

The problem I'm having is that I can't seem to pass the Report object from the report into the user function. I've tried both of the following function signatures but with no luck:

 

Public Shared Function MyPageNumber(ByVal lastGroupOnPage As String, ByVal reportPageNumber As Integer, ByRef report As Object) As Integer

Accidentally hit Post. Guess I can't edit posts. Here's the continuation:

 

Public Shared Function MyPageNumber(ByVal lastGroupOnPage As String, ByVal reportPageNumber As Integer, ByRef report As Processing.Report) As Integer

 

In both cases, I get the same error:

Type mismatch in function arguments. Cannot find an overload of the function MyPageNumber() that accepts arguments of type (String, Int32, Report).

 

Is it possible to pass the Report object to a User Function when using the standalone report designer? I need to be able to reference some parameters in the report.

 

Thanks!

Ugh. One last piece of important information. The expression I'm using to call the user function is the following:

= TelerikRuntimeReportingFunctions.MyPageNumber(IsNull(PageExec("detail", CStr(Last(Fields.WorkOrderNo) ) ),""), PageNumber, ReportItem.Report)

 

If I change the function to accept only the first two arguments, everything works. So it seems as though the mismatch is on the ReportItem.Report type.

Hello James,

ReportItem.Report is the value of the processing report and the signature of the method should be like:
Public Shared Function MyPageNumber(ByVal lastGroupOnPage As String, ByVal reportPageNumber As Integer, ByVal report As Telerik.Reporting.Processing.Report) As Integer

Please note that as of R1 2017 there are built-in Page functions accomplishing the same task.


I hope this information helps.

Regards,
Stef

Yes, thank you Stef. I was using a 2016 version and realized that functionality had been added for R1 2017 shortly after I posted the question. Thanks.
