title: WebDataGrid sorting with a generic list
body: <p>I have a generic collection like this </p>
  
  <pre><code>Dim List(Of t) myData = data.GetData()
  myWebDataGrid.DataSource = myData
  myWebDataGrid.DataBind()
  </code></pre>
  
  <p>the config of the webdatagrid sort is this</p>
  
  <pre><code>&lt;Behaviors&gt;
     &lt;ig:Sorting Enabled="true" SortingMode="Multi"&gt;
        &lt;ColumnSettings&gt;
            &lt;ig:SortingColumnSetting ColumnKey="Key1" Sortable="true" /&gt;
        &lt;/ColumnSettings&gt;
     &lt;/ig:Sorting&gt;
  &lt;/Behaviors&gt;
  </code></pre>
  
  <p>but when I set the sortable property on this control and run the page...
  I just try to sort and all the data disappears.</p>
