ListViewWebPart with Custom Filtered view

ListViewWebPart with Custom Filtered view: "I have any event receiver on a list (Fund) that automatically creates a web part page for the specified Fund. On the web part page I have a ListViewWebPart that displays a document library. I would like this doc library to only display documents that are associated to this Fund. I have been trying to modify the filter by updating the Query of the SPView, but have not been able to get it to work. I have also tried to use the FilterString property from the ListViewWebPart but this has also been unsuccessful."
