Question

How can I resize the height of a ListView depending on how many items are in that ListView? I’m trying to get the text of an item which is clicked, however whenever the user clicks on a space which has no item, there’s an error.
The exact error is:

InvalidArgument=Value of ‘0’ is not valid for ‘index’.
Parameter name: index.

I’m using the code:

label14.Text = myListView1.SelectedItems[0].Text.ToString();

I figured that removing the space below the items will solve this problem. Thanks!

What you should do to fix your error is check to see whether the user actually clicked on an item:

if (myListView1.SelectedItems.Count > 0) {
    label14.Text = myListView1.SelectedItems[0].Text.ToString();
}
