ListView

charles

I am trying to programmatically update a listview and its items in my winForm app. I have it working with literal commands:

ListViewItem item8 = new ListViewItem();
item8.Text = "Windows Server Resource Kit";
this.listView1.Items.Add(item8);

What I really want to do is to do this programmatically. Something like:
public void _updateList(string strApp, string strStatus)
{
ListViewItem li = new ListViewItem();
if (strApp != null)
{
li.Text = strApp;
listView1.Items.Add(li)
}
}
but that is not getting me very far. Anyone have an idea for this one. I guess another way to put it is I want to be able to edit each listviewitem's subitems. Not sure if I need to do an array to get this done or not. Any help is appreciated. Chuck

I have the listview adding the items to the 1st column of the details view. I can also get the lv to add in a subitem. But for some reason the subitem will not update. Here is what I have:

ListViewItem item15 = new ListViewItem();

item15.Text = "Some Text";

lv.Items.Add(item15);

lv.Items[lv.Items.Count - 1].EnsureVisible();

item15.SubItems.Add("Some Text");

Now, if want to change the value of only the subitem I should be able to use: item15.SubItems.Add("Some Other Text");

but for whatever reason it is not updating the subitems text. I have also tried using lv.Items[14].SubItems.Add("Error During Install"); and also lv.Items["some text"].SubItems[0].Text = "Some Other Text";

All to no Avail. Any help on doing this would be great.
