RadGridView RowStyleSelector Condition With a Dataset ItemSource

[Yel]

Hi,
I want to use a RowStyleSelector in a RadGridView to make rows Expandable or not depends on the value of a column of my ItemSource.
ItemSource is a Dataset that contains a DataTable (ID, Name, Type, SerialNumber, ...).
I need to make rows expandable if the Type ='Updated'.

My actual code (below) is not working:
 
<telerik:RadGridView.RowStyleSelector>
                          <telerik:ConditionalStyleSelector>
                                <telerik:StyleRule Condition="Type = Updated">
                                    <Style TargetType="rad:GridViewRow">
                                        <Setter  Property="IsExpandable" Value="False" />
                                    </Style>
                                </telerik:StyleRule>
                            </telerik:ConditionalStyleSelector>
                      </telerik:RadGridView.RowStyleSelector>
