  WPF 4.0, VB, 2010.3.110.40
  
  If I put a button in the Header and click on it the IsExpanded property of the expander does not change (as I expected).
  If I put a checkbox in the Header and click on it the IsExpanded property DOES change (as well as the IsChecked of the checkbox.  How can I have a checkbox in my header but not have it process as if the Expander Headerbar was clicked?
  
  

  <telerik:RadExpander IsExpanded="True">

    <telerik:RadExpander.Header>

      <Grid>

        <Grid.ColumnDefinitions>

          <ColumnDefinition Width="Auto" />

          <ColumnDefinition Width="Auto" />

          <ColumnDefinition Width="*" />

        </Grid.ColumnDefinitions>

        <Label Content="Filter Options" />

        <Button Grid.Column="1" Content="Test" />

        <CheckBox Name="showgrouppanel" Content="Show GroupBy Area" Grid.Column="2" VerticalAlignment="Center" HorizontalAlignment="Right" />

      </Grid>

    </telerik:RadExpander.Header>

  Hi Heather,
  
  Unfortunately, this appears to be a bug in the RadExpander. I have logged it in our PITS system ( Expander: Checkbox in the Expander`s Header fires the Expand/Collapse event of the expander). I updated your points accordingly.

  I am having the same issue with a ComboBox in the header of an Expander. I was hoping to get a status update on this issue. We're hoping to launch a product at the beginning of April and would really like to be able to use this particular UI.

  Hello David,
  
  The issue should be fixed with the upcoming Q1 2011 official release. I hope this time frame is acceptable for you.
