Hi Jean,

We suggest you use the below code example to achieve the custom filtering on ODataV4Adaptor.

Find the code example here:

@using Syncfusion.Blazor.Data

@using Syncfusion.Blazor.DropDowns


<SfDropDownList @ref=ddlObj TValue="string" AllowFiltering="true" TItem="OrderDetails" Placeholder="Select a customer" Query="@Query">

    <SfDataManager Url="https://services.odata.org/V4/Northwind/Northwind.svc/Orders" Adaptor="Syncfusion.Blazor.Adaptors.ODataV4Adaptor" CrossDomain=true></SfDataManager>

    <DropDownListFieldSettings Text="CustomerID" Value="OrderID"></DropDownListFieldSettings>

    <DropDownListEvents TValue="string" TItem="OrderDetails" Filtering="CustomFiltering"></DropDownListEvents>



@code {

    SfDropDownList<string, OrderDetails> ddlObj { get; set; }


    async Task CustomFiltering(FilteringEventArgs args)


        args.PreventDefaultAction = true;

        var query = new Query().Where(new WhereFilter() { Field = "CustomerID", Operator = "contains", value = args.Text, IgnoreCase = true });


        query = !string.IsNullOrEmpty(args.Text) ? query : new Query();


        await ddlObj.FilterAsync(this.ddlObj.DataSource, query);



    public Query Query = new Query().Select(new List<string> { "CustomerID", "OrderID" }).Take(6).RequiresCount();


    public class OrderDetails


        public int? OrderID { get; set; }

        public string CustomerID { get; set; }

        public int? EmployeeID { get; set; }

        public double? Freight { get; set; }

        public string ShipCity { get; set; }

        public bool Verified { get; set; }

        public DateTime? OrderDate { get; set; }

        public string ShipName { get; set; }

        public string ShipCountry { get; set; }

        public DateTime? ShippedDate { get; set; }

        public string ShipAddress { get; set; }
