Answer 1

I had this problem inside a GridView, but it had nothing to do with my GridView. I was splitting addresses by commas, ex addresses[index].split(',')[0], but I came across a address that had no commas which is why I suddenly got this error. Look closely through the debug console to find the exact line of the error, and test every piece of code in your GridView to pinpoint the error.
