Column Frozen in datagrid

[SCosmos]

Hi,
I'd like to know if it's possible to freeze the column when the top text is added and covers several column headers.
Without Title column all columns are well frozen if I add the title column all columns are not frozen

Thanks in advance to your support

<Columns>
         <RadzenDataGridColumn TItem="Developer" Title="Title"   Frozen="true">
           <Columns>
              <RadzenDataGridColumn TItem="Developer" Context="dev" Filterable="false" Sortable="false" TextAlign="TextAlign.Right" Frozen="true" Width="90px">

....
          </Columns>
   </RadzenDataGridColumn>
</Columns>

Composite columns cannot be frozen - it’s not supported.
