Trying to Use LoadMoreElement in Monotouch.Dialog - dialog

Question

I am using Monotouch to write an Ipad app. The app uses tables to browse down through a directory tree and then select a file. I have used Monotouch.Dialog to browse the directories and I set up the directory tables as the app starts.However there are too many files to set up in a table as the app starts and so I want to set up the 'file table' as the file is selected from the lowest level directory table. I am trying to use LoadMoreElement to do this but I cannot make it work or find any examples online. I have coded the 'Elements API Walkthrough' in the Xamarin tutorial at:- http://docs.xamarin.com/ios/tutorials/MonoTouch.Dialog
I then add a new section to the code:-
_addButton.Clicked += (sender, e) => {
++n;
var task = new Task{Name = "task " + n, DueDate = DateTime.Now};
var taskElement = new RootElement (task.Name){
new Section () {
new EntryElement (task.Name,
"Enter task description", task.Description)
},
new Section () {
new DateElement ("Due Date", task.DueDate)
},
new Section()
{
new LoadMoreElement("Passive","Active",
delegate {MyAction();})
}
};
_rootElement [0].Add (taskElement);
Where MyAction is:-
public void MyAction()
{
Console.WriteLine ("we have been actioned");
}
The problem is that MyAction is triggered and Console.Writeline writes the message but the table stays in the active state and never returns to passive. the documentation says:-
Once your code in the NSAction is finished, the UIActivity indicator stops animating and the normal caption is displayed again.
What am I missing?

Answer 1

You need to set the "Animating" property in the element to false.
Like this:
LoadMoreElement loadMore = null;
loadMore = new LoadMoreElement (
"Passive", "Active",
delegate {loadMore.Animating = false;});
Where did you see any documentation that says that the animation stops when the delegate stops running? If that is documented anywhere, that is wrong.
