PFCSIG Detect and get a keystroke in datawindow

[Rendra Yap]

Hello, it's not a PFC question.

I've another problem.
I've a datawindow with many column and I make that datawindow editable (if
possible how to hide letter what I type in -> For incremental search), if I
place my cursor at first column that's mean I want to search at first column
with letter that I type in, so If I type letter 'da' at  the first column
that focus row in that datawindow change to row that begin with letter 'da'
