how I show and get data in the report viewer

[Ricardo]

the sample shows me the message "Unable to progress the report action..."

I want to call the data that is needed and what is the structure used to call that data.

by the way I would like to know which is the structure of the api used in the framework to solve the problem and call it in the report designer if is the same structure, unless it is not, I would make the threat in the right control post.

Hi Ricardo, 

Thanks for your interest in Syncfusion Products. 

We suspect that the issue occurs when our report viewer not able connect with Web API service, so if you are trying to pass any values with header then please refer the below help documentation for passing header value in Ajax request. 

https://reports.syncfusion.com/documentation/javascript/report-viewer/handle-post-actions/#add-custom-header-in-ajax-request 

If your still face any issue then please share the controller class file, RDL report and details regarding how you have specified the controller in client side. It will be helpful for us to provide the solution at the earliest. 

Regards,
