Filter datagrid with TItem with list of objects

Hi, i need to filter a column by item. This is a part of my code:

<RadzenDataGrid Data="@data" AllowAlternatingRows="false" AllowFiltering="true" AllowPaging="true" PageSize="20" AllowSorting="true" class="mb-3">
    <Columns>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Tutorando">
            <Template Context="data">
                <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item3.User.FirstName @data.Item3.User.LastName</RadzenText>
                <RadzenText TextStyle="TextStyle.Caption">@data.Item3.User.Email</RadzenText>
            </Template>
        </RadzenDataGridColumn>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Tutor">
            <Template Context="data">
                <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item1.User.FirstName @data.Item1.User.LastName</RadzenText>
                <RadzenText TextStyle="TextStyle.Caption">@data.Item1.User.Email</RadzenText>
            </Template>
        </RadzenDataGridColumn>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Mentor">
            <Template Context="data">
                @if (data.Item2.User != null)
                {
                    <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item2.User.FirstName @data.Item2.User.LastName</RadzenText>
                    <RadzenText TextStyle="TextStyle.Caption">@data.Item2.User.Email</RadzenText>
                }
                else
                {
....

i want to filter from a column: item1.something for example. It is possible to use advance filter like this away

I've been looking at the documents and I want something like DataGrid dynamic data. I will keep trying

Ya, but in some objects i have column template (Blazor DataGrid custom appearance via column templates)
It possible define a Property value to filter in the way that I have the code?

<RadzenDataGrid Data="@data" AllowAlternatingRows="false" AllowFiltering="true" AllowPaging="true" 
    FilterMode="FilterMode.Advanced" PageSize="20" AllowSorting="true" class="mb-3">
    <Columns>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Tutorando">
            <Template Context="data">
                <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item3.User.FirstName @data.Item3.User.LastName</RadzenText>
                <RadzenText TextStyle="TextStyle.Caption">@data.Item3.User.Email</RadzenText>
            </Template>
        </RadzenDataGridColumn>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Tutor">
            <Template Context="data">
                <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item1.User.FirstName @data.Item1.User.LastName</RadzenText>
                <RadzenText TextStyle="TextStyle.Caption">@data.Item1.User.Email</RadzenText>
            </Template>
        </RadzenDataGridColumn>

                {
                    <RadzenText TextStyle="TextStyle.Subtitle2" Class="mb-0">@data.Item2.User.FirstName @data.Item2.User.LastName</RadzenText>
                    <RadzenText TextStyle="TextStyle.Caption">@data.Item2.User.Email</RadzenText>
                }
                else
                {
                    <RadzenText TextStyle="TextStyle.Subtitle1">Sem mentor</RadzenText>
                }
            </Template>
        </RadzenDataGridColumn>

            <Template Context="data">

            </Template>
        </RadzenDataGridColumn>
        <RadzenDataGridColumn TItem="(Enrollement,Enrollement,Enrollement, Course,int,int)" Title="Nº reuniões">
            <Template Context="data">

            </Template>
        </RadzenDataGridColumn>

            </Template>
        </RadzenDataGridColumn>
    </Columns>
</RadzenDataGrid>

You can filter at data level only - no data from templates can be used when filtering.

what is the best option I have to do?
I pretend to filter this data:

If you need to construct some value runtime better add additional property to your data item with calculated value and later this property can be used in filtering, sorting, templates, etc.

I didn't understand very well, what if I create a class for this specific datagrid, so I use only 1 item object. it legit?

UPDATE: I created a custom class with the attributes I intended to place and this way it is already possible for me to filter

Thanks
