    public string Name { get; set; }
    public int Age { get; set; }
}

    <Columns>
        <RadzenDataGridColumn T="Person" Property="Name" Title="Name" />
        <RadzenDataGridColumn T="Person" Property="Age" Title="Age" />
    </Columns>
</RadzenDataGrid>

@code {
    List<Person> persons;

    protected override void OnInitialized()
