RadzenGrid event onScroll

Good day to all!
I have this situation, I would like to handle the oncroll event on RadzenGrid in order to upload data to Grid when I get to the end of Grid.
But the oncroll event does not work out and does not go into the onscroll handler, can you please tell me what is wrong?
Thanks a lot in advance!

<RadzenGrid @onscroll="OnScroll" AllowFiltering="true" FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" style="height: 800px; overflow-y: scroll; position:fixed;" FilterDelay="800" PageSize="20"
                AllowSorting="true" Data="@MyItems" LoadData="@LoadData" TItem="MyItem" ColumnWidth="200px" Count="@count">

@code {
async Task OnScroll()
        MyItems = await dbContext.techItems.Take((count += 20)).ToListAsync();
        count = MyItems.Count();

I’m afraid that there is no such event.

Can you please tell me how you would solve this situation with loading data from the database when scrolling through the grid?

Such functionally is not supported.
