[RESOLVED] VB2010 Listview: change backcolors

[donW]

How can I access a Listview's subitem, (to change backcolor, text ,etc)
I know the item & subitem index's...

something like this ??
ListView1.listitem(1).SubItems(2).BackColor = Color.Black

What you have posted in exactly the code you would use. You have to set the item's UseItemStyleForSubItems property to False first though, or setting subitem properties like that has no effect.

[.paul.]

your code is right, but you need to set the listviewitem's .UseItemStyleForSubItems to False first for it to work

[donW]

this doesn't work:
ListView1.listitem(1).SubItems(2).BackColor = Color.Black

the IDE complains about the .listitem(1)

Error 2 'listitem' is not a member of 'System.Windows.Forms.ListView'.

ALSO:
what else disables the .backcolor of a subitem?
I had it working, now no color shows after altering some the Listviews properties.
I can't seem to get it back to what worked!

Ah, didn't notice that. It should be Items. Of course, you could always have opened the MSDN documentation and had a look for yourself.

Still can't get this to work!
I get an 'invalid index' on the last line at .items(1) when I run this

        Dim item2 As New ListViewItem("item1", 0)
        item2.SubItems.Add("pink")
        item2.SubItems.Add("blue")
        item2.SubItems.Add("biege")
        item2.UseItemStyleForSubItems = False
        item2.SubItems(1).BackColor = Color.HotPink
        item2.SubItems(2).BackColor = Color.Blue
        item2.SubItems(3).BackColor = Color.Green
        ListView1.Items.Add(item2)

        ListView1.Items(1).SubItems(1).BackColor = Color.Black

[jmcilhinney]

Just like all .NET collections, the ListView.Items collection is zero-based. The index of the first item is 0.

Perhaps the fact that you use 1 as the index for the first subitem is confusing you, but SubItems is zero-based also. SubItems(0) gives you the item itself as a subitem. This means that myListViewItem.Text and myListViewItem.SubItems(0).Text will give you the same text.

Thanks, that fixed it.
I had read about 0 based, but didnt realise it applied to listview index....


PS re my other post, the .GetItemAt seems to work to identify the on screen list index's...
