As I haven't got a response yet let me be a little more specific in my question can you have tool tip like selection completion prompts as in a Google search for Parameters? For example say I am choosing products in a product list and there are thousands of products but I know I am looking for "ABC Widget" as I begin to type in my parameter text box the letters A-B-... SSRS suggests values via tool tip like view which I can choose an option and the selection list becomes more narrow as I provide more letters in the item name.
If this can't be done using SSRS what is best practice for trying to do this sort of thing.
Thanks,
