I'm trying to do something like this...

```
<Style
    x:Key="TwoByTwoGridStyle"
    TargetType="Grid">
    <Setter
        Property="Grid.RowDefinitions">
        <Setter.Value>
            <ControlTemplate>
                <RowDefinition
                    Height="*" />
                <RowDefinition
                    Height="Auto" />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter
        Property="Grid.ColumnDefinitions">
        <Setter.Value>
            <ControlTemplate>
                <ColumnDefinition
                    Width="*" />
                <ColumnDefinition
                    Width="Auto" />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

```

`ControlTemplate` is not right. I get the error: "Property `VisualTree` does not support values of type `RowDefinition`". Is there some way to signify a collection of row/column definitions? Or, is there some other way to create a style/template for a 2x2 Grid?

Thanks.
