title: DataPager not working in Silverlight 3 + RIA Services
body: <p>I have a Silverlight 3 app with RIA Services and I'm running into an issue where my DataPager is only loading data for the initial loadsize and then no longer reloading. It brings up two pages of data (PageSize=10, LoadSize=20.) It is correctly showing 119 pages of data but when I navigate to page 3, nothing appears in my datagrid and dataforms.</p>
  
  <p>This is my Domain Data Source:</p>
  
  <pre><code>&lt;riaControls:DomainDataSource x:Name="_dds" QueryName="GetCaseLoads" AutoLoad="True" PageSize="10" LoadSize="20"&gt;
      &lt;riaControls:DomainDataSource.DomainContext&gt;
          &lt;domain:FooContext /&gt;
      &lt;/riaControls:DomainDataSource.DomainContext&gt;
  &lt;/riaControls:DomainDataSource&gt;
  </code></pre>
  
  <p>Here's the snippet for the DataPager:</p>
  
  <pre><code>&lt;data:DataPager Source="{Binding Data, ElementName=_dds}" /&gt;
  </code></pre>
  
  <p>And here's the Domain Service query:</p>
  
  <pre><code>[RequiresAuthentication()]
  public IQueryable&lt;CaseLoad&gt; GetCaseLoads()
  {
      // Return all case loads
      return this.Context.CaseLoadSet;
  }
  </code></pre>
  
  <p>It's pretty straightforward so I'm not sure what's missing. Any help would be appreciated; </p>
