Brett,
short answer: attach the handler in the ctor.
TL;DR
the code at DialogViewController.cs line 63 is this (MonoTouch.Dialog
source is on github https://github.com/migueldeicaza/MonoTouch.Dialog/):
if (tableView != null)
throw new ArgumentException (You should set the handler before the
controller is shown);
*
*
i guess adding the handler after the tableView has been created is too late
for the MT.D core to wire it up
p.s. i'm not sure you need the NSTimer - i think in Miguel's sample that's
just to create a delay to simulate network activity. in your implementation
just do work to reload your data and call ReloadComplete() when you are
finished.
p.p.s. the MWC app sample implements pull-to-refresh in News Twitter
screens, also on
githubhttps://github.com/xamarin/mobile-samples/blob/master/MWC/MWC.iOS/Screens/Common/News/NewsScreen.cs

Hi Jason,
this is a DialogViewController(). So I implemented a new instance of the
DialogViewController, then put that block of code in the ViewDidLoad()
method.
The app just shuts down stating an exception at DialogViewController.cs
line 63. I have no idea what that means though. MD certainly doesn't
pronounce the exception very well if one is fired.
Any thoughts? Is there a particular order to where I should include the
RefreshRequested block of code?
Cheers,
Brett

what context are you doing this in (ie, what is this - a class derived
from DVC, or something else?)
what specifically is the error when it crashes?

Hi all,
I have a DialogViewController which I am trying to implement the
Pull-to-Refresh functions.
However, everytime I add the line:
this.RefreshRequested += delegate {
NSTimer.CreateScheduledTimer (1, delegate {
this.ReloadComplete();
} );
} ;
it crashes.
I've been trying to follow the example at:
https://github.com/migueldeicaza/MonoTouch.Dialog/blob/master/Sample/DemoRefresh.cs
which works when I run the sample project. But when I try to move the
logi to my own app, it crashes.
The Table displays just fine. It's only when I add the RefreshRequested
handler that it crashes.
Does anyone have any experience with this?
Many thanks!
Brett
