GroupBy Collumns in diferent levels

[Regula]

Hello!
I'm trying to use a RadGrid with two of the columns grouped.

If I try to group the two collums day are displayed at the same level like this:

Group A  Group 1
Data
Group A Group 2
Data
Group B Group 1

I would like to display the data this hierarchical way:

Group A
   Group 1
           Data
   Group 2
           Data
Group B
   Group 1
            Data

In this demo http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/outlookstyle/defaultcs.aspx if I drag From column I get the appearance I wish to have on my form.

My pseudo-code of what I have in the GroupBy zone:

<telerik:RadGrid.....

<GroupByExpressions>

                     <telerik:GridGroupByExpression>

                         <SelectFields>

                             <telerik:GridGroupByField FieldAlias="Field1" FieldName="Field1" HeaderValueSeparator=" : " SortOrder="Ascending" >

                             </telerik:GridGroupByField>

                             <telerik:GridGroupByField FieldAlias="Field2" FieldName="Field2" SortOrder="Ascending" FormatString="{0:D}"

                                 HeaderValueSeparator=" : "></telerik:GridGroupByField>

                         </SelectFields>

                         <GroupByFields>

                             <telerik:GridGroupByField FieldName="Field1" SortOrder="Ascending"> </telerik:GridGroupByField >

                             <telerik:GridGroupByField FieldName="Field2" SortOrder="Ascending"></telerik:GridGroupByField>

                         </GroupByFields>

                     </telerik:GridGroupByExpression>

                 </GroupByExpressions>
...</telerik:RadGrid>

Please! Can anybody help me?
I'm sure that this isn't difficult but I'm a newbie in the Telerik controls.

Any help is welcome!
