ProgressBar on GridView at row level??

Hi, it is about a Telerik RadGridView. Yes,I've posted a thread on their forums but I don't still get a response and it is urgent.

That's the XAML code for that but for GridView WPF 4.5 (VS 2012):

<DataGridTemplateColumn Header="Actual" Width="80" Visibility="Visible">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <ProgressBar Value="{Binding Path=Stock_Actual, Mode=OneWay}" Minimum="0" Maximum="{Binding Stock_max}" />
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

A picture is worth a thousand words, so I attach you my need (look at Actual field)

Thanks in advance for your help

Primary platform is Windows 7 Ultimate 64 bit along with VS 2012/Sql2k8 for WPF/SilverLight projects.
