Are you using a data set to derive your parameters? ....

I'm not and would very much like to do this. Can you advise me or provide a sample?

Also, I have yet to get "Select All" set as my default, or even all the values in the list checked as default. I'm using VS2005. I must not understand the thread completely because I set the From Query to my dataset that populates my list, but it didn't check all the items in the list.

Any advice would be appreciated. Thank you!
