[RockLala]

Hi Everyone,

I am some what new in thingworx., right now i am using thingowrx 8.4 version. i want to complete one task where i need select multiple Item from an dropdown list and pass all selected item to an services and base on selected item need to fetch some other details from database table. 

Till the time I can able to select multiple item by enabling  multi-selected property of dropdown , but i don't know how i can pass it to an services, do i need to created datashape ? if yes then what should be there filed ?

is there any other option to complete this work ? 

Thanks in advance,

You  need a custom service that will consume infotable input with an appropriate datashape. Then you can bind selected rows to feed  to that service.

Does the service work when you test it through the Composer directly (via "execute"/test button)? Does it send any output to a different widget, say, grid?

think for your kind reply.

yes. because when i am testing that services and if i am not passing any data as input  of service it  does not provide any output  which is correct one. and in case if i pass some data as input to that datashape i am getting same as output. 

But, what i  am thinking is as am manually passing data so it is giving same output but on same time while i am binding selected row data to as a input to the services it is not giving actual output so, problem might be in binding. could you please help me on that.
