Hi Subramaniam,
Thanks for your interest in Syncfusion components.
If your requirement is to show the data at runtime in viewer based on user input then use the RDLC report to achieve your requirement. You can get the data from the user and convert those details into a business object, then load these business objects as a datasource to RDLC report. Please find the help documentation for rendering RDLC report in report viewer.
If the user input from the user is like form filling then it can be achieved using RDLC and ReportParameter. Please find a Knowledge Base article regarding this from the below link.
If the above solutions not meet with your requirement, then could you please provide some additional details regarding your requirement. It will be helpful for us to provide the solution at the earliest.
Regards,
Vinoth S.
