Custom Toolbox shapes

[Zickige]

     Hi there,

I want to be able to show symbol shapes in the toolbox but create the actual shapes when it is dropped on the diagram. right now gallery items accept a shape but cant change the appearance of it. style templates didnt work either. any idea how to do this ?

I have the following template but If I remove the content presenter or the view box i cant create any shapes on the diagram. Currently used template:

<DataTemplate x:Key="ToolboxItemTemplate">
        <Grid Margin="0 1 1 0" Width="72" Height="auto">
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>

            <Viewbox VerticalAlignment="Bottom" HorizontalAlignment="Center" Margin="5 5 5 0">
                <ContentPresenter Content="{Binding Shape}" Margin="5" IsHitTestVisible="False"  />
            </Viewbox>

            <TextBlock Grid.Row="1" Text="{Binding Header}" TextWrapping="Wrap" Margin="5" FontSize="12"
                    TextAlignment="Center" FontFamily="Segoe UI Semibold" HorizontalAlignment="Center" VerticalAlignment="Top"/>
        </Grid>
    </DataTemplate>
