<p>All Better ListView elements, element collections and some support

serialized</em></strong>. These classes implement <span class="code">ISerializable</span>

and <span class="code">IXmlSerializable</span> interfaces. They are also marked by

<span class="code">SerializableAttribute</span>.</p>

<h2>Comparing Elements and Collection by Value</h2>
|
||
|
||
|
||
<p>When you need to check whether two objects from Better ListView
|
||
(namely elements or collections) are same, you can serialize them and
|
||
compare the serialized data. More efficient way to do the same is to call
|
||
<span class="code">EqualsContent</span> method.</p>
|
||
|
||
<p>When using <span class="code">EqualsContent</span> on element instances, this
|
||
method checks whether the two elements have same text, font, color...
|
||
rather than whether there are the same instance (as happens with
|
||
<span class="code">Equals</span> ro <span class="code">ReferenceEquals</span>):</p>
|
||
|
||
<p><strong>C#</strong></p>
|
||
<pre class="prettyprint"><code class="lang-cs">// create some item
|
||
BetterListViewItem item1 = new BetterListViewItem("new iem");
|
||
|
||
// create second item as a clone of the first
|
||
BetterListViewItem item2 = (BetterListViewItem)item1.Clone();
|
||
|
||
// check whether item1 and item2 are different instances
|
||
item1.Equals(item2); // returns false
|
||
|
||
// check whether item1 and item2 have properties with the same values
|
||
item1.EqualsContent(item2); // returns true</code></pre>
|
||
|
||
<p><strong>Visual Basic</strong></p>
|
||
<pre class="prettyprint"><code class="lang-vb">' create some item
|
||
Dim item1 As New BetterListViewItem("new iem")
|
||
|
||
' create second item as a clone of the first
|
||
Dim item2 As BetterListViewItem = DirectCast(item1.Clone(), BetterListViewItem)
|
||
|
||
' check whether item1 and item2 are different instances
|
||
item1.Equals(item2) ' returns false
|
||
|
||
' check whether item1 and item2 have properties with the same values
|
||
item1.EqualsContent(item2) ' returns true</code></pre>
|
||
|
||
<br><hr>
|
||
<p class="note">When using <span class="code">EqualsContent</span> on collection instances,
|
||
this method check whether both collections contain the same instances of
|
||
collection items. It does not compare collection items by content. To do
|
||
this, you still need to iterate both collections and call
|
||
<span class="code">EqualsContent</span> on each collection element.</p>
