Hi Nicolas Guinot,

You may use the Header property of the column you define. Within the header you may place any UI element instead of the string.
For example you may place a rotated TextBlock in the header to achieve your goal.

Something like :

<telerik:RadTreeListView ItemsSource="1234" AutoGenerateColumns="False" >
           <telerik:RadTreeListView.Columns>
               <telerik:GridViewColumn Width="40">
                   <telerik:GridViewColumn.Header>
                       <Border Width="100" Height="100">
                           <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="Rotated">
                           <TextBlock.RenderTransform>
                               <RotateTransform Angle="90" />
                           </TextBlock.RenderTransform>
                           </TextBlock>
                       </Border>
                   </telerik:GridViewColumn.Header>
               </telerik:GridViewColumn>
           </telerik:RadTreeListView.Columns>
       </telerik:RadTreeListView>
