title: Progress Bar Bind Value
body: <p>Fixed.  Had to Bind both the Maximum and Value and it worked.  In the test I bound both to Int32 (did not test binding both to double). Microsoft I think this is a bug.</p>
  
  <pre><code>   &lt;ProgressBar Grid.Row="8" Grid.Column="0" HorizontalContentAlignment="Stretch" Height="20" Maximum="{Binding Path=DF.WFBatchFolderStatus.DocCount}" Value="{Binding Path=DF.WFBatchFolderStatus.DocCountComplete}" PresentationTraceSources.TraceLevel="High" /&gt;
  </code></pre>
  
  <p>What is protocol.  If I answer my own question should I delete the question?</p>
  
  <p>I get an error when I try to bind Value for a Progress Bar.  XamlParseException 'Set property 'System.Windows.Controls.Primitives.RangeBase.Value' threw an exception.' Grid.Row 8 fails and Grid.Row 9 Fails.  When I put in fixed values (Grid.Row 6 and Grid.Row 7) it works.  I can retrieve the value I want to bind to in a TextBlock (Grid.Row 5).  I have tried binding to Double and Int 32.  According to the documentation Minimum, Maximum, and Value are double.  The calculated value it is failing on is 2 (and it fails on other values).  Thanks in advance and I will mark the answer.</p>
