I have an rdlc report in asp.net.
I have a table in it and I am using group by in that table. But the columns which I make Parent Group or child group has Column Visibility Disabled.

Notes Column is in a group. See its visibility option is disabled.
How can I hide that column on the basis of a criteria as I can do with the Exam Date column that is not in any group.
Please help.
I’ve concluded that it’s not possible to do this.
