Hi,

My forms are a pageframe control with editing parts on first page and on second page the grid with searching controls.

Clues for searching is in heading of column or in a wait window; if this doesn't enough you may try to display a sign on form above grid while user are typing( display sign with blinking for each keystroke and hide sign by a timer).

Another idea: on clik of headings of columns I put code for setting order by that column 1 click ASC, 2-nd click DESC and 3-d click unordered ( with indexes on that data ).
