Dynamic Elements Scale

I've got custom items control container which uses a custom data template to display the hosted items.
I'd like to control the size of each item in order to support dynamic number of displayed items.
I've modified my custom data template to have binding to the ScaleX and ScaleY properties of the root grid Layout ScaleTransform .
When I launched the application I've noticed that the bindings don't work. The ScaleX and ScaleY properties of the ScaleTransform simply use their default value which is 1..
Any suggestions how to dynamically control the scale of my elements?

Could you please write a small piece of xaml so we can see the logical/visual tree. This way we can guess what could be happening.
Thanks.

Here it is -
Note that the binding for the visibility property works well..
<DataTemplate x:Key="CubrDataTemplate">
<Grid x:Name="grid" Height="Auto" Width="Auto" Background="{x:Null}" Margin="1" Visibility="{Binding TraineeVisibility, Mode=OneWay}">
<Grid.LayoutTransform>
<TransformGroup>
<ScaleTransform ScaleX="{Binding TraineeLayoutScaleX, Mode=OneWay}" ScaleY="{Binding TraineeLayoutScaleY, Mode=OneWay}"/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</Grid.LayoutTransform>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="64"/>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="64"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="40"/>
<RowDefinition Height="80"/>
<RowDefinition Height="40"/>
</Grid.RowDefinitions>
</Grid>
</DataTemplate>

Something I forgot to ask, are you using 1.1 or 1.2 version?
And about the DataTemplate, is it used something like this?
<ItemsControl ItemsSource="{Binding Items}" ItemTemplate="{StaticResource CubrDataTemplate}"/>

I'm using 1.1 and the usage is exactly as you mentioned.

I was able to reproduce the problem, we are looking into this issue.
I'll let you know when we found a solution.
Thanks for reporting.

In the meanwhile I was able to make it work by finding the host UI Container and apply the layout transform explicitly to it...

Ok, good to know.
Anyhow I found the source of the problem, so you will find this issue solved in the next release.
