Trouble downloading file from DB

Radzen Studio Blazor Server

Atanas,

I got the controller to work with the data from the db.

When i post this from a form all works as expected and the PDF apears as it should . Now i want to call this from a button in a datagrid. I have almost got it to works but not quite.

When i click the yellow button in my datagrid it routes correctly to the controller and it returns but I do not get the PDF.


        [Inject]
        NavigationManager navigationManager { get; set; }
        
        public async Task PostFormAsync(int docID)
        {
            HttpClient client = new HttpClient();

            var Json = JsonConvert.SerializeObject(docID);
            var stringContent = new StringContent(Json, Encoding.UTF8, "application/Json");

            var response= client.PostAsync($"{navigationManager.BaseUri}api/Download/DownloadFile/{docID}", stringContent);

What am I missing to get the PDF to finally display?

thanks

John
