如何使用Crystal Report在C＃Winforms中仅在运行时显示报告中的选定字段？

Question

I am developing an win forms application for now i want to generate a crystal report that is dynamically. Means if my table contains 30 fields so i will design my 30 fields on front end just take checkbox or dropdown so, based up on the user selection i want to generate report ie,dynamically. So i have already but i got a bunch of errors just like as asking prompt message for enter a value.(If i have set list of values option as "Dynamic" too)

Those issues are not solvable me i irritated a lot.

Can you give me any reference or procedure to make report as dynamic in my win forms using c# and database as SQL.

Thanks help me out.

In case of dynamic Report with dynamic fields, I afraid you have to create the report programmatically. So you can iterate over all existing objects in your report in ReportDocument and either take them out or add them to the report depending on the date you want to visualize.
