ListViewItem question

[naikrovek]

Hello all.

I have a ListView on a form, that has columns added at design-time but
will be populated run-time. So, I know what the columns will be, and I
know that I will have an arbitrary number of 'rows' in the ListView,
anywhere from 1 to 100 or even 1000.

The purpose of the program is to allow a user to keep an eye on tickets
in a ticketing database.

The user selects a ticket type from a drop down, and enters a ticket
number in a text box, then clicks 'add'. This adds those strings to
the first two columns of the ListView, and I want to be able to fill in
the rest of the columns of that 'row' programmaticall y based on data
from a database.

How do I access each element in the 'rows'? I use "rows" because I
don't know of a more correct term.

All I've gotten so far is this:

foreach (ListViewItem lvi in lvRecords.Items ) {
}

I've tried accessing lvi.SubItems but I'm not at all sure how to make
it work.

Can anyone share information on how to access individual cells in the
ListView programmaticall y?

Here is a code snippet I had handy that illustrates getting at the subItems
of each ListViewItem:

private void btnDone_Click(o bject sender, EventArgs e)
{
if (this.listView1 .Items.Count == 0)
{
this.Close();
return;
}
ListViewItem myItem = null;
int checkedItems = 0;
//string sipUserId = String.Empty;
foreach (ListViewItem itm in this.listView1. Items)
{
if (itm.Checked)
{
myItem = itm;
checkedItems++;

}
}
if (checkedItems > 1)
{
this.lblMessage .Text = "Check 1 Item only.";
return;
}
else if (checkedItems == 1)
{
// myItem.SubItems[1].Text+" "
this.chosenSipU serId = myItem.SubItems[0].Text +"|"
+myItem.SubItem s[2].Text;
this.OnNotifyCa ller();
this.Close();
}

} // end btnDone_Click

that solution is so simple I've glossed over it at least 20 times
trying to figure it out.

For those of you that don't see it: SubItems[int].Text

Thank You Very Much, Peter.
