Setting Blazor Grid EnablePersistence=true does not persist column filter

[David Adler]

I am using SyncFusion.Blazor v18.2.0.47

I have a grid where I have a FilterTemplate on a column to allow the user to select from a dropdownlist. This all works as expected. However, now I need to persist the selected filter when I navigate away from the page with the list so that the filter is applied once I navigate back to the list.

I have EnablePersistence="true" on the grid. When I apply the filter, navigate away and then navigate back, it does not apply the filter.

I tried applying a sort as well, using the built-in grid sorting, and when I sort, navigate away and then navigate back, the sort persists as expected. Just the filter is not persisting. 

Here is my Grid markup;

        <SfGrid @ref="@Grid" ID="productList" TValue="Product" AllowPaging="true" AllowFiltering="true" AllowSorting="true" EnablePersistence="true">

            <GridEvents OnActionComplete="ActionCompleteHanlder" TValue="Product"></GridEvents>

            <GridPageSettings PageSize="@DefaultPageSize" PageSizes="@PageSizes"></GridPageSettings>

            <SfDataManager Headers="@HeaderData" Url="@CdApiUrl" Adaptor="Adaptors.ODataV4Adaptor"></SfDataManager>

            <GridSortSettings>

                <GridSortColumns>

                    <GridSortColumn Field="Name" Direction="SortDirection.Ascending"></GridSortColumn>

                </GridSortColumns>

            </GridSortSettings>

            <GridColumns>

                <GridColumn HeaderText="" Width="150px" AllowFiltering="false">

                    <Template>

                        @{

                            var product = (context as Product);

                            <button Class="btn btn-outline-primary"

                                    @onclick="@(_ =>

                                              {

                                                  if (product != null) HandleProductSelectClick(product.Id);

                                              })">

                                <span class="far fa-edit"></span> Manage

                            </button>

                        }

                    </Template>

                </GridColumn>

                <GridColumn Field=@nameof(Product.PartNumber) HeaderText="Part Number" FilterSettings="@Filtering" Width="150"></GridColumn>

                <GridColumn Field=@nameof(Product.Name) HeaderText="Product Name" FilterSettings="@Filtering"></GridColumn>

                <GridColumn Field=@nameof(Product.ProductChannel) HeaderText="Channel" Width="150">

                    <FilterTemplate>

                        <SfDropDownList PlaceHolder="Channel Type" ID="Channel" Value="@((string)(context as PredicateModel).Value)" DataSource="@ChannelTypeValues" TValue="string" TItem="string">

                            <DropDownListEvents ValueChange="@HandleChangeChannelTypeFilter" TValue="string"></DropDownListEvents>

                            <DropDownListFieldSettings Value="string" Text="string"></DropDownListFieldSettings>

                        </SfDropDownList>

                    </FilterTemplate>

                </GridColumn>

                <GridColumn Field=@nameof(Product.Status) HeaderText="Status" Width="150px">

                    <FilterTemplate>

                        <SfDropDownList PlaceHolder="Status Type" ID="Status" Value="@((string)(context as PredicateModel).Value)" DataSource="@StatusTypeValues" TValue="string" TItem="string">

                            <DropDownListEvents ValueChange="@HandleChangeStatusTypeFilter" TValue="string"></DropDownListEvents>

                            <DropDownListFieldSettings Value="string" Text="string"></DropDownListFieldSettings>

                        </SfDropDownList>

                    </FilterTemplate>

                </GridColumn>

            </GridColumns>

        </SfGrid>

And here are my handlers for applying the filters;

        protected void HandleChangeStatusTypeFilter(ChangeEventArgs<string> args)

        {

            if (args.Value == "All")

            {

                Grid.ClearFiltering();

                ShowClearFilterButton = false;

            }

            else

            {

                Grid.FilterByColumn("Status", "equal", args.Value, null, true);

                ShowClearFilterButton = true;

            }

        }

        protected void HandleChangeChannelTypeFilter(ChangeEventArgs<string> args)

        {

            if (args.Value == "All")

            {

                Grid.ClearFiltering();

                ShowClearFilterButton = false;

            }

            else

            {

                Grid.FilterByColumn("ProductChannel", "equal", args.Value, null, true);

                ShowClearFilterButton = true;

            }

        }

What am I missing here?
