The following code works ONCE,. then when I click on another item in the listview, I get an index error.

Code:

I didn't try this in VS.NET 2005, but I have 2003 and 2008 on my machine and tested...

When I put a ListView on a form and double-clicked to edit code, the default event it opened was ListView1_SelectedIndexChanged

I got the same behavior you describe.  I manually went in to code view, and added event handler for ListView1_Click, which sounds more appropriate anyway as you describe your need.  In that event handler, I entered the following code:

TextBox1.Text = ListView1.SelectedItems.Item(0).Text

I rarely program forms apps so I can't tell you off the top of my head why this behavior occurs, but based on what I know about VB and .NET framework, I'd guess that the indexchanged event fires your code off at an inappropriate time.  ListViews can be 'multi-dimensional' I guess when you use columns and whatnot, so indexchanged is not the same thing as click, or even close.  This is why ListView has the SelectedIndices properties.  At any rate, running the code on the ListView1.Click event rather than indexchanged event seems to work as I think you desire.

When you wish to loop through, you could probably use code below, still in the .Click event, with a loop on items.Count  It will work if you are using a simple ListView with no complex properties etc:

Private Sub ListView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click

Dim i as integer
TextBox1.Text = ""
For i = 0 to (ListView1.SelectedItems.Count - 1)
TextBox1.Text &= ListView1.SelectedItems.Item(i).Text & vbcrlf
Next
End Sub



'The & vbcrlf adds a line break - I"m assuming multiline textbox but you can format the string as
'you wish

Not only was the answer correct, but you went above and beyond and explained both a "why" and a "how" (as in how you got there)

awesome answer!
