Hi Guys,

Is it possible to have a report with CONTROLLER and DATA PROVIDER class only? I'm not needing the contract class coz the report data filtering is only based on the active record.

Please see screenshot below :

• As you can see I used variable _dpClass to call the method "getSalesId" in DP class method, why? I fetch the active record to "getSalesId" method of DP class for me to filter the report.

Please see debugging screenshot :

• Base on my debugging process under controller class, the line code 17 works good and was able to debug and get the active record.

• I was confused on line code 18 where I called the method from dp class to fetch na value. As per may debugging it gets the correct active record but when I run the report it's all blank.

Please see DP class method screenshot below :

I'm quite confuse why it doesn't work to throw value on the public method on my DP class.

Does the way I called my DP class method is not appropriate?

Many thanks for the help guys!

Try to compile, CIL and cache clear and run the code again. By the way, why not use data contract class to pass sales Id as parameter. You can hide Parameter dialog and pass sales Id in controller class as parameter.

You can follow this link.

Contract classes are used to hold parameters. You say that you need a parameter (an active record), therefore where would you put it if not to a contract class? Your claim that you don't need a contract class lacks any explanation.

That you have the record in your controller class before executing the record is nice, but it won't magically appear in the RDP object constructed by the report (possibly on a different server at a different time). You need serializable parameters that the will be used by the RDP class in such a situation, which is exactly the role of contract classes.

Hi Ali Raza,

Thanks for this. I'll use contract instead and just hide the dialog called by the controller.

Based on my analysis and debugging the controller class passes parameter on method(only not classdeclaration) in my DP class but controller class only calls the SSRS which runs my DP class. SSRS running my DP class which CLEAR all variables and run as an initial not holding or retaining the parameter I fetch on the DP method. That is why still gets blank result.

I'll be using your link to hide the controller dialog. Thank you for this very good option.

I've got it and just realize that contract was the one holding all parameters upon prerun of the DP class. Thank you for this Martin. :)
