Sorry for my english. I added a single line delete event from listview

                var button = sender as Image;
                var training = button.BindingContext as TDiary;
               
                HttpClient client = new HttpClient();
               
                var result = await client.DeleteAsync("Uri/api/training/" + $"{training.Id}");

My removal webapi is as follows:

  [HttpDelete("{id}")]
    public ActionResult Delete(int id)
    {

        var training = context.Trainings
                   .FirstOrDefault(m => m.Id == id);

        //czy zasob istnieje
        if (training == null)
        {
            return NotFound();
        }

        context.Remove(training);
        context.SaveChanges();

        return NoContent();
    }

In TDiary class I keep training Id. I don't know why, but I can't delete any lines.

ReVoPEP

are you asking how to remove it **from the ListView** after you delete it from your service? – Jason Dec 11 '20 at 00:42
I would like to delete a row in the database – ReVoPEP Dec 11 '20 at 01:01
then this really has nothing to do with Xamarin. If you're using Entity Framework, you should add that tag too – Jason Dec 11 '20 at 01:04
@ReVoPEP Hi, which type of database you used in project? – Junior Jiang Dec 11 '20 at 01:45
relational database ms sql – ReVoPEP Dec 11 '20 at 02:21
