I have created a class library to get the records from database. I have given a project reference to report class library. Its working when the website was running. But the preview is not showing the output. It showing the error as "Could load the file or assembly.....".
I have already saw some example. But they either using the code that retrieves the record from database in report library itself or using dataset.
So kindly tell me the solution and is there any alternative for this requirement?
