Hi Iki
for (int i = 0; i < newsList.Count; i++)
{
StringElement se = new StringElement(newsList[i]);
section.Add(se);
int localCounter = i; //grab it, 'cos you want to use it
inside the lamda, and "i" may have the wrong scope
se.Tapped += () =>
{
//DialogViewController with modified ctor (string name)
DetailViewController dvc = new
DetailViewController(newsList[localCounter]); //use the local one
this.NavigationController.PushViewController(dvc,true);
};
stringElementsList.Add(se); //you dont need this, you are
storing it in the section above!
}
you might not need the localCounter bit (you might just be able to use
i) - try it out. If it always shows the last element, regardless, then
use the localCounter bit. I know you need to do this for objects, just
not 100% sure on value types :)
you could rewrite it like this, too:
newsList = new List<string>()
{
"News - 1"
,"News - 2"
,"News - 3"
,"News - 4"
};
foreach(var s in newsList)
{
string temp = s; //capture outside, use inside the lambda/delegate
section.Add(new StringElement(s, () => {
DetailViewController dvc = new DetailViewController(temp);
this.NavigationController.PushViewController(dvc,true);
});
}
