How to access NavigationController.PushViewController under UITableViewSource?

Question

How can I access NavigationController inside UITableviewSource class?

On Row selection I want to navigate to another UIController.

This is my code,

public class RootTableSource : UITableViewSource
{
    IList<VendorDetails> tableItems;
    string cellIdentifier = "UIViewController";

    ReportsList reportList;
    AddNewReport addnewReport;

    public RootTableSource()
    {
    }

    public RootTableSource (IEnumerable<VendorDetails> items)
    {
        tableItems = items.ToList (); 
    }

    public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
    {
        tableView.DeselectRow (indexPath, true); 

        // Redirect to another UIController....
    }

    public VendorDetails GetItem (int id)
    {
        return tableItems [id];
    }
}

Answer 1

The way I do this is by passing a reference to the TableViewController when I create my Source. Then the Source can use this reference to access it's parent's NavigationController.

UITableViewController _parent;

public RootTableSource (IEnumerable<VendorDetails> items, UITableViewController parent)
{
    tableItems = items.ToList (); 
    _parent = parent;
}


public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
{
    tableView.DeselectRow (indexPath, true); 

    _parent.NavigationController.PushViewController(...);
}

have you instance UINavigationController in AppDelegate ?

like this...

@property (strong, nonatomic) UINavigationController *navigationViewController;

then you should can access UINavigationController from AppDelegate delegate

#import "AppDelegate.h"

@implementation yourClassName

-(void)functionName{

    AppDelegate *appdelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];

    appdelegate.navigationViewController;  //your UINavigationController

    [appdelegate.navigationViewController pushViewController:yourUIViewController animated:YES];

}

@end

wish help ~

edit:

Sorry i have never use Xamarin before

so i think this is a bad way to implement ...

but it look work

AppDelegates.cs

[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{

    UIWindow window;
    HomeScreen home;
    public static UINavigationController navigation;
    //set navigation public and static      

    public override bool FinishedLaunching (UIApplication app, NSDictionary options)
    {
        window = new UIWindow (UIScreen.MainScreen.Bounds);
        home = new HomeScreen ();
        navigation = new UINavigationController(home);
        window.RootViewController =  navigation;
        window.MakeKeyAndVisible ();
        return true;
    }
}

yourClassName.cs

AppDelegate.navigation
//access navigation
