reporting services - How to select the Data Source at Runtime in SSRS Report Builder -


before going problem let me clear know there similar questions ask before not find answer of problem. problem is:
want select data source @ runtime. first of all, create report making shared data source. create data set using data source. run report , working perfectly. create 2 parameters, 1 data source , 1 data set. both parameters type of "text", parameter visibility "visible" , available , default values "none". created second data source embedded , connection string :
="data source=" & parameters!datasource.value & ";initial catalog=" & parameters!dataset.value
when click on test connection button shows me error :
"the connectionstring property has not been initialized."
can 1 please explain me how handle it. credentials correct. test credentials making embedded data source , hard codded connection string working fine not dynamic connection string.

you can't use shared data source dynamic data source. use embedded one. think it's prevent corrupting other reports' data sources.
