<p>Every item within the list view can contain sub-items. These can be
|
|
accessed using <span class="code">BetterListViewItem.SubItems</span> collection.</p>
|
|
|
|
<p>Sub-items are displayed only in the <strong><em>Details</em></strong> view
|
|
when the columns are present. Each item can have any number of sub-items,
|
|
but the number of sub-items displayed is limited by the number of column
|
|
headers.</p>
|
|
|
|
<p>The following screenshot shows Better ListView with items and
|
|
sub-items displayed on the right of each items (in columns) with one
|
|
sub-item being focused (see <strong><em><a href="chapter-focus.html">Focusing
|
|
Elements</a></em></strong> for more information):</p>

<h2>Copying sub-items</h2>
|
|
|
|
|
|
<p>The sub-item collection behaves differently than other collections
|
|
present in Better ListView.</p>
|
|
|
|
<p>It always have to contain at least one sub-item. Even if you call
|
|
<span class="code">Clear</span> method, one sub-item remains in the collection. This is
|
|
because this sub-item represents properties of the item itself.</p>
|
|
|
|
<p>To copy sub-items from one item to another, you have to consider
|
|
<strong><em>setting</em></strong> the first sub-item, while adding the
|
|
other:</p>
|
|
|
|
<p><strong>C#</strong></p>
|
|
<pre class="prettyprint"><code class="lang-cs">itemTarget.SubItems[0] = (BetterListViewSubItem)itemSource.SubItems[0].Clone();
|
|
|
|
for (int indexSubItem = 1; indexSubItem < itemSource.SubItems.Count; indexSubItem++)
|
|
{
|
|
itemTarget.SubItems.Add((BetterListViewSubItem)itemSource.SubItems[indexSubItem].Clone());
|
|
}</code></pre>
|
|
|
|
<p><strong>Visual Basic</strong></p>
|
|
<pre class="prettyprint"><code class="lang-vb">itemTarget.SubItems(0) = DirectCast(itemSource.SubItems(0).Clone(), BetterListViewSubItem)
|
|
|
|
For indexSubItem As Integer = 1 To itemSource.SubItems.Count - 1
|
|
itemTarget.SubItems.Add(DirectCast(itemSource.SubItems(indexSubItem).Clone(), BetterListViewSubItem))
|
|
Next</code></pre>
