Thanks a lot for your feedback.

Yes, for finding, it requires incremental search. This can be done easily adding a text box in the search window (inspired from Esgici's code). You may find this in my other project's entry form (where there was no find button, but entry form itself had a grid and on top of the grid there is a text box for incremental search).
For incremental search we can also use CSB (combo search box) from HFCL library.
Very good point friend. Next time I shall work on how we can use a search window within a grid. Is there any example for this?
