How to display datagrid as childproperty in tree component

I have the following tree component

RadzenTree Data="@controlTypes" Visible="true">
RadzenTreeItem Text="Components">
RadzenTreeLevel TextProperty="Type" ChildrenProperty="TblControl">
RadzenTreeLevel TextProperty="ReferenceNum">

but I want to display datagrid with several columns in tblControl instead of just TextProperty="ReferenceNum" ( one text column) How can I achieve this?

Thank you in advance
