Hi Menna,

I have reproduced the behavior without the usage of TreeView ItemTemplate. I have used this setup: 

<telerikDataControls:RadTreeView  x:Name="treeView" FlowDirection="RightToLeft" Grid.Row="2"
                                  ItemsSource="{Binding Source}">
            <telerikDataControls:TreeViewDescriptor DisplayMemberPath="Name"
                                            ItemsSourcePath="Cities"
                                            TargetType="{x:Type local:Country}"/>
            <telerikDataControls:TreeViewDescriptor DisplayMemberPath="Name" 
                                            TargetType="{x:Type local:City}"/>
</telerikDataControls:RadTreeView>

In order to apply the correct margin you need to implement a LevelToMargin converter

I have attached the xaml and xaml.cs files I used. Please check them. 
This is the result when RightToLeft flow direction is set to the TreeView and LevelToMargin is applied:
