<body class='hmmessage'><div dir='ltr'>John, thanks for the response. <br><br>You are correct - the TListBox component "OnClick" event does indeed respond to the keyboard, but unfortunately the same event on the TListView component only responds to mouse clicks. Whether this component is just a wrapper around a MS component that only responds that way I don't know.<br><br>So, still a problem to sort out.<br><br>Also, another question - how to make one of the columns (the caption in my case) invisible - like using the "Visible" property on the columns of a DBGrid or a dataset. There is no "Visible" property on the Items or SubItems properties.<br><br>All this would have been super easy with a database but I am trying to avoid that if possible at present.<br><br><div><hr id="stopSpelling">From: johnkbird@paradise.net.nz<br>To: delphi@listserver.123.net.nz<br>Date: Mon, 28 Jul 2014 02:24:33 +1200<br>Subject: Re: [DUG] ListView - Scroll Event<br><br>

<div>Haven’t tried with Listview, but in stringgrid and listbox, checkbox etc
the onclick event fires with the mouse, or on moving with the arrow key
(D2007). (As long as there is a current element its more or less logical
to have a click event also respond to the keyboard as it wouldn’t be much use
otherwise). I have used stringrids and listboxes to do exactly what you
want – as current record changes in the first to show more detail in a second
control.</div>
<div> </div>
<div>(With data controls often the best approach is to use the change event on
the datasource to detect the same thing).</div>
<div> </div>
<div>So try the onclick event some more.</div>

<div dir="ltr">(Delphi 7)<br><br>I wish to detect the user selecting a row
(item) in a ListView component to display child records for the item in
another control. <br><br>There is no "OnScroll" event for this
control. I can use the "OnClick" event OK for a selection cia the mouse,
but how do I detect when a user scrolls on to a record by using the arrow keys
(or PgUp, PgDn or moving the scrollbar ?<br><br>I have tried the using the
OnChange event but it seems that there are two events generated for each
movement by the arrow keys.<br><br>Does anyone have a code snippet to accomplish
this?<br><br>Eric.<br></div>
