Unable to load the DetailViewController.

Is there any way to load DetailViewController on rowSelected.

When you create your table, you need to place it within the context of a Navigation controller.

UINavigationController nav = new UINavigationController(myTableViewController);

Then, when you want to display your DetailViewController, you can push it onto the already existing Navigation controller. However, by default your TableSource does not have access to NavigationController - you will need to pass a reference to your TableView controller when you create the TableSource so that the TableSource can access the NavigationController:

// in your controller, when you assign the source
this.TableView.Source = new MyTableViewSource(this);

// in your source, keep a class level ref to the parent
MyTableViewController _parent;

// your Source's constructor
public MyTableViewSource(MyTableViewController parent) {
  _parent = parent;
}

// finally, in your RowSelected use the _parent reference to access the Nav controller
var detailController = new DetailViewController ();
_parent.NavigationController.PushViewController(detailController, true);
