Silverlight 3 - FindName returns null

This looks a bug to me.. Using Silverlight 3 and i have a user control defined in XAML and trying to access the object during runtime returns a null.

<Grid>
  <common:CommonGridEditPanel x:Name="scannerParameters" Grid.Row="0" DataContext="{Binding Parameters}">
  <common:CommonGridEditPanel.Columns>
</Grid>

scannerParameter variable is assigned with null value, on further digging i noticed the below code in auto-generated section of the file.

this.scannerParameters = ((CommonGridEditPanel)(this.FindName("scannerParameters")));

Is t开发者_开发技巧his a known bug ?
