Template Support Toolbar

Hi,
I want to ask about templating.

From the sample project, it gives some samples for templating the ProperyGrid.
But all template samples doesn't support IsToolBarVisible property.

Can we make template that support the toolbar?
And can we also change template for toolbar itself?

Another question about templating,
When the property is a collection,
at the end of every item there is a button mark with 'x'.
Is that for remove item from collection?
I don't want user to add/remove item from collection, can I hide that button for this purpose?

Thanks.

To add the standard toolbar to the template, just include a ViewCommandsToolBar in the template.  Bind its visibility to IsToolBarVisible and its Target to the BindingView of the property grid being templated (e.g. via a {RelativeSource AncestorType...}).  Typically you would wrap everything in a DockPanel with the ViewCommandsToolBar docked to the top:

<DockPanel>
  <ms:ViewCommandsToolBar DockPanel.Dock="Top"
    Visibility="{Binding IsToolBarVisible, RelativeSource={RelativeSource AncestorType={x:Type ms:PropertyGrid}}, Converter={StaticResource BooleanToVisibility}}"
    Target="{Binding BindingView, RelativeSource={RelativeSource AncestorType={x:Type ms:PropertyGrid}}}" />
  <ms:TreeListView x:Name="PART_Grid" ...

ViewCommandsToolBar is just a control and you can change its template using normal control templating techniques.  Your buttons should send the commands defined on the ViewCommandsToolBar class, and if you want filtering, you must include a TextBox called PART_FilterText.

You can hide the collection add/remove buttons by setting the grid's AllowModifyCollections property to False. 

Thanks, Ivan.
That's very helpful.

One another question.
How to make template with splitter and expander.

Poppy.xaml is an example of template overrides property grid, can split the column but the expander on the left most grid disappear.

Whalesong.xaml create template for ItemTemplate in TreeListView.
It has expander, but can't split the grid.
If I change the border which separate between property name column and value column in item template with grid splitter, it will split each column. Not whole of column.

How to make enable the expander and splitter.

Thanks.

There's an explanation of how to restore the expander to the Poppy sample at http://www.mindscape.co.nz/forums/Thread.aspx?PostID=1709 (scroll down to the last message but one).  Hopefully that will resolve your problem, but if not, just let me know!
