Can anyone ponit me to examples of how to use?

I have created a Listview and can add items and subItems, but how do I edit
them??

i have a ListView with 10 items, each has 5 sub items
How do I change the value of Item 2 subitem 4??
are there any "Seek" methods to find ListItems by value?

All the documentatiopn i have found is quite skim.
Even the "Examples" in the on-line help doesn't include the ListView??

You accessthe SubItems by using the Item's SubItems collection. Fair
warning, SubItem[0] is the Item itself so always start at 1.

// Items are zero-based but actual SubItems start at index one
listView1.Items[1].SubItems[4].Text = "newValue"

Not that I know of.

Why doesn't the intellisense work when I try your Method???

WhenI type:
ListView[
it doesn't impy there is an index
also
After typing ListView[0].
the intellisense doesn't come up with anything???

but the line of code does work as you explained???

Thanks Frank, I can now get the 1st col to update using
lvEvents.Items[0].SubItems[0].Text = "newValue";

BUT if I use

lvEvents.Items[0].SubItems[1].Text = "newValue";

the second column doesn't update the change??????

Make sure you have the control's View property set to View.Details.
That's the only mode which will show columns beyond the first and the
subitems they contain.

If I change a value
Debug.WriteLine(lvEvents.Items[0].SubItems[3].Text);

lvEvents.Items[0].SubItems[3].Text="AAAA";

Debug.WriteLine(lvEvents.Items[0].SubItems[3].Text);

it shows the change in the Debug window but NOT in the Grid??

How do I get the grid to reflect the change??

I tried "Refresh" but that didn't work?
