grid operations (sort, filter) release rows per page in pager

[Aleksandr]

so if you have several options to select from in pager & selected non default one (100 - default, 200 - selected) than filter or sort grid, the value in pager will be reset to default

Hi Aleksandr,

Here is a test page, which works as expected. I assume you need to change something in the Grid paging configuration. Let me know of your findings.

<TelerikGrid Data="@GridData"
             Pageable="true"
             @bind-PageSize="@PageSize"
             Sortable="true"
             FilterMode="GridFilterMode.FilterRow">
    <GridSettings>
        <GridPagerSettings PageSizes="@PageSizes" />
    </GridSettings>
    <GridColumns>
        <GridColumn Field=@nameof(Product.Name) Title="Product Name" />
        <GridColumn Field=@nameof(Product.Price) Title="Price" />
        <GridColumn Field=@nameof(Product.Quantity) Title="Units In Stock" />
    </GridColumns>
</TelerikGrid>

@code {
    List<Product> GridData;

    int PageSize { get; set; } = 5;
    List<int?> PageSizes { get; set; } = new List<int?> { 5, 6, 7, 20, null };

    protected override void OnInitialized()
    {
        GridData = new List<Product>();
        var rnd = new Random();

        for (int i = 1; i <= 50; i++)
        {

            GridData.Add(new Product()
            {
                ID = i,
                Name = "Product " + i.ToString(),
                Price = (decimal)rnd.Next(1, 100),
                Quantity = (short)rnd.Next(1, 100)
            });
        }
    }

    public class Product
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public decimal Price { get; set; }
        public short Quantity { get; set; }
    }
}
