Need a little help

I have a RadzneDataGrid that is filled with data. The DataGrid has the option DataGridSelectionMode.Single and when I execute some other component that I reach with NavigateTo and return with same NavigateTo, the datagrid knows all the values based on which it could restore the table with all selected data that was before the call of the other component. In the OnAfterRenderAsync section I execute the following code:

‚‚‚

            if (pendingSelection && grid0 != null)
            {
                pendingSelection = false;
                await grid0.Reload();
                var match = gKGKNCollection?.FirstOrDefault(x => x.BRNAL == brnal);
                if (match != null)
                {
                    brnal = 0;
                    await grid0.SelectRow(match, true);
                    StateHasChanged();
                }
            }
‚‚‚

everything works as I expect and all the values in the variables are as they should be but the line in the RadzenDataGrid is not marked as selected.
What did I miss to do?

You need either @bind-Value or a RowSelect handler.

If you refer to RadzenDataGrid definition it looks like this:

        <RadzenDataGrid @ref="grid0" ColumnWidth="200px"   AllowFiltering="true"  Density="Density.Compact" FilterMode="FilterMode.CheckBoxList" AllowPaging="false"   AllowSorting="true" ShowPagingSummary="true"  Style="flex: 1; height: 100%;"
            Data="@(gKGKNCollection)" TItem="ErpBox.Models.ERPDATA.GKGKN" RowDoubleClick="@EditRow" AllowVirtualization="true"
                            SelectionMode="DataGridSelectionMode.Single" @bind-Value="@selectedGkn" RowSelect="@SelRow">

so @bind-Value and RowSelect are working as they suppose to but when I OnAfterRenderAsync I tried to reestablish selected row every property has values but selected record is not rendered as selected.

StateHasChanged() of the page might not cause rerender while Reload() will do. I don’t know the context of your scenario however you might need to call Reload() after SelectRow() to force the DataGrid to rerender with selected row styles.

Unfortunately no luck. Can you help me if I make a small example?
And if the answer is positive what is the proper way to send it?

Here is an example with DataGrid first demo:
