<p>Better ListView provides methods for storing its content (items with
|
|||
|
|
columns and groups) in a file or stream:</p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">SaveContentBinary(string filename)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">SaveContentBinary(Stream stream)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">SaveContentXml(string filename)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">SaveContentXml(XmlWriter writer)</span></p>
|
|||
|
|
</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Analogically, there are methods to retrieving the stored content
|
|||
|
|
back:</p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">LoadContentBinary(string filename)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">LoadContentBinary(Stream stream)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">LoadContentXml(string filename)</span></p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><span class="code">LoadContentXml(XmlReader reader)</span></p>
|
|||
|
|
</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Storing Better ListView content in a file is very easy. The Following
|
|||
|
|
sample shows storing the content in a binary file:</p>
|
|||
|
|
|
|||
|
|
<p><strong>C#</strong></p>
|
|||
|
|
<pre class="prettyprint"><code class="lang-cs">// save Better ListView items, columns and groups in a XML file
|
|||
|
|
this.listView.SaveContentBinary("listview-content.dat");
|
|||
|
|
|
|||
|
|
// clear content to ensure it is loaded back correctly
|
|||
|
|
this.listView.Clear();
|
|||
|
|
|
|||
|
|
// restore content from file
|
|||
|
|
this.listView.LoadContentBinary("listview-content.dat");</code></pre>
|
|||
|
|
|
|||
|
|
<p><strong>Visual Basic</strong></p>
|
|||
|
|
<pre class="prettyprint"><code class="lang-vb">' save Better ListView items, columns and groups in a XML file
|
|||
|
|
ListView.SaveContentBinary("listview-content.dat")
|
|||
|
|
|
|||
|
|
' clear content to ensure it is loaded back correctly
|
|||
|
|
ListView.Clear()
|
|||
|
|
|
|||
|
|
' restore content from file
|
|||
|
|
ListView.LoadContentBinary("listview-content.dat")</code></pre>
|
|||
|
|
|
|||
|
|
<p>The content can be stored in either binary or XML format. For example,
|
|||
|
|
to store the content in a stream as formatted XML, use the following
|
|||
|
|
code:</p>
|
|||
|
|
|
|||
|
|
<p><strong>C#</strong></p>
|
|||
|
|
<pre class="prettyprint"><code class="lang-cs">XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8);
|
|||
|
|
|
|||
|
|
writer.Formatting = Formatting.Indented;
|
|||
|
|
|
|||
|
|
listView.SaveContentXml(writer);
|
|||
|
|
|
|||
|
|
writer.Close();</code></pre>
|
|||
|
|
|
|||
|
|
<p><strong>Visual Basic</strong></p>
|
|||
|
|
<pre class="prettyprint"><code class="lang-vb">Dim writer As New XmlTextWriter(stream, Encoding.UTF8)
|
|||
|
|
|
|||
|
|
writer.Formatting = Formatting.Indented
|
|||
|
|
|
|||
|
|
listView.SaveContentXml(writer)
|
|||
|
|
|
|||
|
|
writer.Close()</code></pre>
|
|||
|
|
|
|||
|
|
<p>Note that in this case it is necessary to have
|
|||
|
|
<span class="code">XmlTextReader.WhitespaceHandling</span> property set to
|
|||
|
|
<span class="code">None</span> when loading content from formatted XML stream because
|
|||
|
|
white spaces need to be skipped during the deserialization process.</p>
|
|||
|
|
|
|||
|
|
<p>Standard <strong><em><a href="chapter-serialization.html">Serialization</a></em></strong> mechanisms are
|
|||
|
|
used to store elements and its properties. The methods named above store
|
|||
|
|
also mapping between items and their corresponding groups. This cannot be
|
|||
|
|
done when simply serializing <span class="code">Groups</span> or <span class="code">Items</span>
|
|||
|
|
collection.</p>

cleared.</p>
