Listview won't show text [resolved]

[wossname]

This code won't actually show up any text in the listview even though its View property is set to Details.

		Dim lvi As ListViewItem

		With lvProcesses
			.Clear()

			For i As Integer = 0 To Procs.GetUpperBound(0)
				lvi = New ListViewItem(Procs(i).id)
				lvi.SubItems.Add(Procs(i).Name)
				lvi.SubItems.Add(Procs(i).Priority)
				lvi.SubItems.Add(Procs(i).Boost)
				.Items.Add(lvi)
			Next i
		End With

What gives?

Hi.

Did you remember to add the columns first?

You can add as many subitems you want, but without the columns to display them, nothing happens.

[wossname]

Yeah, I did it from the properties pane in the IDE.

?!?

shoulddn't you declare a new listview item INSIDE the loop? that way, a new item is declared. otherwise, the loop overwrites the same one over and over.

I thought the .clear method was the problem but that's out of the loop. (much like I am at work)lol

Well, no because when the sub goes out of scope the listview will still contain all the data. Each new listviewitem is assigned, added to the control and then overwritten.

I have just tried adding an item from the properties pane but that doesnt work either!

Bug???

I wouldn't say it's a but because I've not read of one like that (not saying it's NOT but it would be the first I'VE heard of it.)

hmm.is it possible to zip your project and post it? I'd like to see if it works or not on MY computer.

I've got your fix!

Try this:

Dim lvi As ListViewItem

		With lvProcesses
			.Items.Clear()

			For i As Integer = 0 To Procs.GetUpperBound(0)
				lvi = New ListViewItem(Procs(i).id)
				lvi.SubItems.Add(Procs(i).Name)
				lvi.SubItems.Add(Procs(i).Priority)
				lvi.SubItems.Add(Procs(i).Boost)
				.Items.Add(lvi)
			Next i
		End With

Just change ".Clear()" to ".Items.Clear()"

I think ".Clear()" was clearing your columns too, therefore messing up your subitems.

Worked for me!

that's right! I tried that out and it did the same for me. funny how a small detail like that can screw up your day

at least it's not as bad as c++ where a 'dot' misplaced could take weeks to find!!!

Brilliant!

What a hero.
