Solved it myself with help from the blogs.

As far as I understand you simply can't do the attached property binding inside.

The following solves the problem in an instant (ItemContainerStyle!):

<DataTemplate DataType="{x:Type TestApp:GridVM}">
        <ItemsControl ItemsSource="{Binding Path=Children}">
            <ItemsControl.ItemContainerStyle>
                <Style>
                    <Setter Property="Grid.Row" Value="{Binding GridRow}" />
                    <Setter Property="Grid.Column" Value="{Binding GridColumn}" />
                </Style>
            </ItemsControl.ItemContainerStyle>
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <Grid ShowGridLines="True"  Style="{Binding Path=Style}">
                        <Grid.RowDefinitions>
                            <RowDefinition Height=".5*" />
                            <RowDefinition Height=".5*" />                            
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width=".5*" />
                            <ColumnDefinition Width=".5*" />
                        </Grid.ColumnDefinitions>                        
                    </Grid>
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
        </ItemsControl>
</DataTemplate>
