PivotGrid Way to disable collapsing on a ColumnGroupDescription

[Fitz]

Is there a way within Wpf to disable collapsing of a Column Group Description?
I have a Type, SubType and then Aggregations. 
Currently the user can collapse the Type on the Column Group.
I want to prevent them from collapsing all the types and leave the last one open.

Hi David,

You should be able to hide the expand/collapse button by modifying the ControlTemplate of PivotGroupHeader, for example you can set the Visibility of the Grid named PART_ExpandIcon to Collapsed. However note that this will affect all the GroupHeader levels, so you might also need to use a ValueConverter in order to hide/show only the needed GroupHeaders.

Hope this helps.

Never mind I used a style and set the control template on the PivotGroupHeaders.

This is what I used to do this, but it isn't quite right.  How do I get to the named Grid to set the Visiblity?  Or do I have to use Blend?
This actually removed the PivotGroupHeader and replaced it with a Gird that was hidden.  I want to set the Visiblity on the Grid named PART_ExpandIcon.  Any help with it you can lend will be appreciated?

<Style TargetType="pivot:PivotGroupHeader">
        <Setter Property="Template">
          <Setter.Value>
            <ControlTemplate TargetType="{x:Type Grid}">
              <Grid Name="PART_ExpandIcon" Visibility="Hidden">
              </Grid>
            </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>

Here is the correct xaml:
 <Style TargetType="pivot:PivotGroupHeader">
        <Setter Property="Template">
          <Setter.Value>
            <ControlTemplate TargetType="pivot:PivotGroupHeader">
              <Grid Name="PART_ExpandIcon" Visibility="Hidden">
              </Grid>
            </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>
