UITableviewCell GetCell未被调用

Question

I am using Visual Studio Community 2017 for Mac. I have a UITableview named SchoolSchedule . I am setting the Source from a button, but then when I click the button GetCell is not called, however, RowsInSection is called. Here is my class:

 public class ScheduleTableViewSource : UITableViewSource
{
    private Schedule[] school;

    public ScheduleTableViewSource(Schedule[] school)
    {
        this.school = school;
    }

    public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath)
    {
        var cell = (ScheduleCell) tableView.DequeueReusableCell("cell_id", indexPath);
        var school1 = school[indexPath.Row];
        cell.Updatecell(school1);
        cell.TextLabel.Text = school[indexPath.Row].Site;
        return cell;
    }

    public override nint RowsInSection(UITableView tableview, nint section)
    {
        return school.Length;
    }



}

here is my button code :

 partial void Get_button_TouchUpInside(UIButton sender)
    {

        bool check = NetworkInterface.GetIsNetworkAvailable();
        if(check)
        {

            Service1 client = new Service1();
            var school = client.CypressRidge("CypressRidge");
            SchoolSchedule.Source = new ScheduleTableViewSource(school);
            SchoolSchedule.ReloadData();

        }
        else{
            Console.Write("Error no Internet connection");
            return;
        }
     //   int stop =0;

    }

I have checked and there is data coming in from my service. so that is not the problem. can anyone help?

Answer 1

I had to deleted the table and make a new one. there a bug in Xamarin.

我有同样的问题，我设法修复它设置TableView第一个原型行的标识符属性 - 在故事板中

Answer 3

In addition to implementing the IUITableViewDelegate and IUITableViewDataSource interfaces in the .cs file, calling RegisterNibForCellReuse, and assigning the table view's EstimatedRowHeight, it's easy to forget to set the data source and delegate properties of the table view in the XIB.
