<div class="markdown level1 remarks"><pre><code>&lt;p&gt;The &lt;code class=&quot;paramref&quot;&gt;e&lt;/code&gt; is not strictly required, but is usually available since drag drop operations 
</code></pre>
<p>are initiated by mouse actions. If you don't have a <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.windows.input.mouseeventargs">MouseEventArgs</a> to provide, pass <b>null</b>
instead.</p>
<p>The method causes the drag operation to start, then returns immediately. The caller is responsible for
monitoring and completing the operation using the <a class="xref" href="C1.WPF.C1DragDropManager.DragStart.html">DragStart</a>, <a class="xref" href="C1.WPF.C1DragDropManager.DragEnter.html">DragEnter</a>,
<a class="xref" href="C1.WPF.C1DragDropManager.DragOver.html">DragOver</a>, and <a class="xref" href="C1.WPF.C1DragDropManager.DragDrop.html">DragDrop</a> events.</p>
