[RESOLVED] VB2010 Listview: determine which items are visible

With the Listview in Details view:
When showing a long (scrolling) list:
Is there an (easy) way to return the index's of which range of items are currently visible in the control?

There's nothing specific that I'm aware of, but you could probably use the GetItemAt and/or GetItemRect methods and deduce the first and last items from that.

Note that I didn't know the answer to your question so I just opened the MSDN documentation for the ListView and had a look to see what was available. If I can do that, you can do that.

try this:

vb Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim visibleRange = (From item In ListView1.Items _
                       Let lvi = DirectCast(item, ListViewItem) _
                       Where lvi.Bounds.Top > ListView1.GetItemRect(0).Height AndAlso lvi.Bounds.Bottom < ListView1.Height _
                       Select lvi.Index).ToArray
    MsgBox(String.Join(",", Array.ConvertAll(visibleRange, Function(i) i.ToString)))
End Sub
