Horizontal scrolling does not work in DataGrid

I can't get the DataGrid to scroll horizontally. I use my own Layout

    <RadzenSidebar @bind-Expanded="@sidebar2Expanded">
        <NavMenu />
    </RadzenSidebar>
    <main>
        <RadzenBody>
            @Body
        </RadzenBody>
    </main>
</RadzenLayout>
<RadzenDataGrid 
            AllowFiltering="true" AllowColumnResize="true" AllowAlternatingRows="false"
            FilterMode="FilterMode.Advanced" AllowSorting="true" PageSize="10" AllowPaging="true"
            PagerHorizontalAlign="HorizontalAlign.Left" ShowPagingSummary="true" Data="@allrows" TItem="RegistryModel"
            LogicalFilterOperator="LogicalFilterOperator.Or" EmptyText="Нет записей"
             @bind-Value=@selectedRow RowClick="@(() => OnClick("Редактировать"))"
            Style="height: 300px;" ColumnWidth="200px">

Maybe the problem is in the Layout? Or did I forget to enable some property on the DataGrid? Thank you!

To scroll horizontally the DataGrid or some of the DataGrid containers will need to have width. Check the code of our demos for reference.
