DataGrid LoadData not working in webassembly


I just want to ask for help because I can't make the DataGrid work in my Webassembly project but my other project with Server side it is working fine.

I follow the guide in your website and included false

The issue is on the first load of the page LoadData is not triggered.

Thank you!

Works normally on my end:

Hi Mr. enchev,

Good Day!

Thank You for the immediate response. I will try it in a new project and hope I succeed. I think there is no problem with it but it's not working. The LoadData is triggered only when you search/Filter.
Below is my code.

<div class="row">
<div class="col-md-12">
    <RadzenGrid AllowFiltering="true" FilterCaseSensitivity="Radzen.FilterCaseSensitivity.CaseInsensitive" AllowPaging="true" PageSize="10" AllowSorting="true" Data="@applications" TItem="Application" ColumnWidth="200px" LoadData="@(args => GetData(args))" Count="@cnt">
            <RadzenGridColumn TItem="Application" Property="AppID" Title="Application ID" />
            <RadzenGridColumn TItem="Application" Property="LName" Title="Last Name" />
            <RadzenGridColumn TItem="Application" Property="FName" Title="First Name" />
            <RadzenGridColumn TItem="Application" Property="MName" Title="Middle Name" />
            <RadzenGridColumn TItem="Application" Property="ExtName" Title="Ext. Name" />
            <RadzenGridColumn TItem="Application" Property="Address" Title="Address" />
            <RadzenGridColumn TItem="Application" Property="BrgyName" Title="Barangay" />
            <RadzenGridColumn TItem="Application" Property="TownName" Title="Town" />


@code {

HttpClient Http = new HttpClient();
List<Application> applications = new List<Application>();
ApplicantInspectionGrid applicantInspection = new ApplicantInspectionGrid();
int cnt = 0;    

async Task GetData(LoadDataArgs args)

        applicantInspection.Top = args.Top.ToString();
        applicantInspection.Skip = args.Skip.ToString();
        applicantInspection.OrderBy = args.OrderBy;
        applicantInspection.COAID = 114;

        var stringPayload = JsonConvert.SerializeObject(applicantInspection);
        var content = new StringContent(stringPayload, Encoding.UTF8, "application/json");
        var response = await Http.PostAsync("http://localhost:50197/api/Application/GetApplicantForInspection", content);
        var responseToString = await response.Content.ReadAsStringAsync();
        JObject obj = JObject.Parse(responseToString);
        applications = JsonConvert.DeserializeObject<List<Application>>(obj["Contents"].ToString());
        cnt = Convert.ToInt32(JsonConvert.DeserializeObject(obj["Count"][0]["TotalRows"].ToString()));
        //acctname = applications[0].AppName;

    catch (Exception ex)


Try to set null as initial value
