DataLoad not working on RadzenDropDown

Radzen.Blazor Components

I’ve been having some trouble when using the RadzenDropDown along with the LoadData for custom filtering. Followed the example for the dropdown with custom filtering.

<RadzenDropDown AllowClear="true"
                    LoadData=@OnLoadData AllowFiltering="true"
                    Data=@users TValue="UserVm" @bind-Value=@selectedUser Style="width: 100%; max-width: 400px;" Name="DropDownFilteringLoadData" />

@inject AzureService AzureService

@code {
    UserVm selectedUser;

    IEnumerable<UserVm> users;

    async Task OnLoadData(LoadDataArgs args) // Load data from external source
    {
        if (args.Filter is null)
        {
            return;
        }

        users = await AzureService.GetAllUsersFromSearchPattern(args.Filter);
    }
}

It triggers the LoadData when the page renders. But it does not trigger when searching in the DropDown not even when pressing enter.

Running Radzen 8.3.8

How do i fix it?

Just checked our demo and it works normally:

You can debug/compare our demos to your app to check what’s different. The source code is here:

Make sure also your app is interactive. - i.e. a basic button can fire onclick event.
