Well, what I mean is that, AFAIK, a) A filtered grid is slow. b) A grid with a parameterized view is fast - unless the parameterized view fetches a lot of data for a specific key value. Which seems to be precisely your problem.

One possibility is to show the users all data that start with a certain letter(s) - using this as the view's parameter, or one of the parameters.

If the user types only a single letter (or none at all!) and then presses a "Show" button, he will have to put up with a longer loading time. That is, users should type at least one, better two or more, letters, most of the time.
