Iterate over columns of a report to dynamically show/hide them?
问题 I want to try and implement a parameter which will allow users to dynamically choose which columns are going to be shown in a report. An idea is to create a multiple value parameter which has column names. After user hit View Report I want to try iterate over columns and selected values to join visibility. How I can iterate over columns inside a tablix? How I can iterate over multiple values of a parameter, so I can find if some value is selected or not? I am using MS SQL Reporting Services
