Showing/Hiding Webparts when filtering

[homeguard]

Ok so i have two lists on a webpart page

One list (the upper) is a list of projects.

the second list (lower) is a list of tasks for each project.

I have list one with the projects filtering list 2 (tasks) with the project ID.

I want make it so no tasks will show up unless the user uses the option button (filter button) next to the project on the upper list.

right now all the task show up when you go to the site and it makes users confused, does anyone have a work around for this? maybe make the page automatically filter for say project ID of Zero (doesnt exist) and make the list show nothing?

Thanks.

i never got it completely solved, i did convert the XSLT data view and that allows you to do conditional formatting with a XPath expression. I did get it to not show up data in the list when the page first loads(based on the url) but for some reason when i try it with a url that is filting a list it doesnt work. I am not sure but i think the XPath PageUrl function cuts off the url at a certain length but i havent figured this out yet.

Let me know what you come up with as a solution.
