Is there a way to repeat the column headers inside each group of a ListView.GridView when using a grouped CollectionViewSource as the source of the ListView?
I am using the example at http://msdn.microsoft.com/en-us/library/ms754027.aspx which uses an Expander control to display each group.
I would like the column headers to appear inside the expander for each group instead of at the top of the ListView.
I haven't tried this, but you may be able to include GridViewHeaderRowPresenters inside your group headers:
<GridViewHeaderRowPresenter
DataContext="{Binding View, RelativeSource={RelativeSource FindAncestor,ListView,1}}"
Columns="{Binding Columns}"
ColumnHeaderContainerStyle="{Binding ColumnHeaderContainerStyle}"
ColumnHeaderTemplate="{Binding ColumnHeaderTemplate}"
ColumnHeaderTemplateSelector="{Binding ColumnHeaderTemplateSelector}"
AllowsColumnReorder="{Binding AllowsColumnReorder}"
ColumnHeaderContextMenu="{Binding ColumnHeaderContextMenu}"
ColumnHeaderToolTip="{Binding ColumnHeaderToolTip}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
If that doesn't work, one sure-fire way to do it is to add a Rectangle that is painted with a VisualBrush that references the one-and-only GridViewHeaderRowPresenter at the top of the GridView.
This can be done with an attached property to be used on the Rectangle. When the attached property is set, it registers a low priority Dispatcher callback that:
The Rectangle itself would be something like this:
<Rectangle HorizontalAlignment="Stretch"
Height="{Binding Fill.Visual.RenderHeight}"
my:GridViewHeaderHelper.SearchForHeaderRowPresenterAndSetFill="True" />
