Double-Clicking Item in ListView

Question

So I added a list view, and I am displaying 3 columns of strings in each. I also have the full row select on. I want to be able to double click on one of the rows, and have it return the string in the 3rd column. I've tried to look everywhere for a solution to this, but so far nothing comes up.

My code so far is:

private void listView_MouseDoubleClick(object sender, MouseEventArgs e)
{
    MessageBox.Show(songList.SelectedItems[2].ToString());
}

Yet it returns an error saying "InvalidArgument=Value of '2' is not valid for 'index'. Parameter name: index"

Answer 1

You could try:

if (songList.SelectedItems.Count > 0) 
{
    ListViewItem item = songList.SelectedItems[0];
    string s_you_want = item.SubItems[1].Text;
}

Taken a ListViewItem , you can take columns values using SubItems[] property.

Answer 2

SelectedItems returns a SelectedListViewItemCollection and with the indexer you are accessing elements in this collection, ie ListViewItems, not the columns. this means that if you have a single row selected the collection contains only one item, and trying to access the third one gives you the error.

Try (edit according to Marco's comment):

songList.SelectedItems[0].SubItems[1].Text

Answer 3

I think that you hould bound not your listView to doubleClick event, but listViewItem. sender will have DataContext, from which you can get your third column.

Answer 4

How do you fill the ListView ? Wihtout knowing this, it's difficult to help. May be you could try this:

Set a breakpoint in this line:

MessageBox.Show(songList.SelectedItems[2].ToString());  

As soon as the debugger hits the breakpoint you could select songList and hit Shift-F9.
Now you can explore the songList and check yourself how to get the string of the third column.
