After doing some research, I came across the &lt;a href="http://msdn2.microsoft.com/en-us/library/ms745786.aspx" target="_blank"&gt;&lt;span style="mso-bidi-font-size: 11.0pt"&gt;MSDN how-to article&lt;/span&gt;&lt;/a&gt; that described a basic way of accomplishing this task. &lt;a href="http://blogs.msdn.com/atc_avalon_team/archive/2006/03/03/542803.aspx"&gt;&lt;span style="mso-bidi-font-size: 11.0pt"&gt;This blog post&lt;/span&gt;&lt;/a&gt; also has the same example explained. Unfortunately, though, it relied upon using the Column Header text as the property name on the underlying colllection on which to sort. After implementing the example, I decided this stank. Actually, I realized this stank beforehand, but wanted to implement the example anyways. &lt;?xml:namespace prefix ="" o /&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;It stinks because Column Headers can contain anything. They don&amp;#8217;t necessarily contain text. They could contain a button, a list, a drawing, a 3D animation, etc. Furthermore, even if they did just contain plain text, who&amp;#8217;s to say that the text in the column header is actually a property name on my underlying object? What if I used &amp;#8220;Birth Date&amp;#8221; as the column header text and the property value was &amp;#8220;DOB?&amp;#8221; While the example was simple and made to be that way, I wanted a bit more control of how my GridView sorted. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;I&amp;#8217;m not going to dive into all the problems I see with the GridView and the ViewBase aspects of WPF in this blog, but that isn&amp;#8217;t to say that I don&amp;#8217;t think there are a ton of problems with this half-assed implementation. I&amp;#8217;m just going to talk about the simple solution that I came up with.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;I decided that in order to make my solution semi-intuitive, I needed to describe on the column level, what property on the underlying object it should sort on. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;Something that looks like this written in XAML:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;&lt;&lt;span style="COLOR: #a31515"&gt;GridViewColumn&lt;/span&gt;&lt;span style="COLOR: blue"&gt; &lt;/span&gt;&lt;span style="COLOR: red"&gt;Header&lt;/span&gt;&lt;span style="COLOR: blue"&gt;=&lt;/span&gt;"&lt;SPAN style="color: blue"&gt;ID&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; &lt;/span&gt;&lt;span style="COLOR: red"&gt;DisplayMemberBinding&lt;/span&gt;&lt;span style="COLOR: blue"&gt;=&lt;/span&gt;"&lt;SPAN style="color: blue"&gt;{Binding ID}&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; &lt;/span&gt;&lt;/span&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;SortPropertyName&lt;/span&gt;&lt;/b&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;=&lt;/span&gt;&lt;/b&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;"&lt;SPAN style="color: blue"&gt;ID&lt;/SPAN&gt;"&lt;/span&gt;&lt;/b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt; &lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;Width&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;=&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;"&lt;SPAN style="color: blue"&gt;50&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; /&gt;&lt;/span&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;That being said, if I wanted to add properties I needed to extend the current GridViewColumn object to contain them so I was really talking about creating a new Grid View Column, extending the existing one. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;So my XAML would really look like:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;&lt;&lt;/span&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: #a31515; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;local&lt;/span&gt;&lt;/b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: #a31515; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;:SortableGridViewColumn&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt; &lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;Header&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;=&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;"&lt;SPAN style="color: blue"&gt;ID&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; &lt;/span&gt;&lt;span style="COLOR: red"&gt;DisplayMemberBinding&lt;/span&gt;&lt;span style="COLOR: blue"&gt;=&lt;/span&gt;"&lt;SPAN style="color: blue"&gt;{Binding ID}&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; &lt;/span&gt;&lt;/span&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;SortPropertyName&lt;/span&gt;&lt;/b&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;="ID"&lt;/span&gt;&lt;/b&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt; IsDefaultSortColumn&lt;/span&gt;&lt;/b&gt;&lt;b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt"&gt;=&amp;#8221;True&amp;#8221;&lt;/span&gt;&lt;/b&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt; &lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;Width&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;=&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;"&lt;SPAN style="color: blue"&gt;50&lt;/SPAN&gt;"&lt;span style="COLOR: blue"&gt; /&gt;&lt;/span&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;

Something like:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: red; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;xmlns:local&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;=&lt;/span&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;"&lt;SPAN style="color: blue"&gt;clr-namespace:ModelingTool&lt;/SPAN&gt;"&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;

This was actually quite easy. I created a new CS file named SortableGridViewColumn.cs and then inherited from GridViewColumn and added a new dependency property called SortPropertyName&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"&gt;&lt;span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Verdana','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'"&gt;Here&amp;#8217;s the code.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt"&gt;&lt;font face="Calibri" size="3"&gt;Defining the new SortableGridViewColumn control was the first step. For true encapsulation, the ListView should actually handle all of the sorting internally. (In fact, it should be the GridView that handles the sorting internally. Unfortunately, the GridView doesn&amp;#8217;t provide any mechanism to accomplish this as it isn&amp;#8217;t a real control, but is actually a View; a very important difference.)&lt;/font&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt"&gt;&lt;font face="Calibri" size="3"&gt;To complete the ListView&amp;#8217;s sorting capabilities, we have to create a new ListView that encapsulates the sorting functionality. We&amp;#8217;ll call it the SortableListView and it&amp;#8217;ll inherit from ListView.&lt;/font&gt;&lt;/p&gt;
&lt;p class="MsoNormal" style="MARGIN: 0in 0in 10pt"&gt;&lt;font face="Calibri" size="3"&gt;Here&amp;#8217;s the code in all it&amp;#8217;s glory.&lt;/font&gt;&lt;/p&gt;
