The key is not in the dictionary; what makes you believe that it is supposed to be there? :-)
What's the point showing exception stack without showing the code throwing the exception?

The Strings dictionary on your custom Data class doesn't contain an entry with the key TitlesByFundsFY16.

Since we can't see the definition of your custom class, only you can find out why that entry doesn't exist.

yes thank you very much i got it ..there was no string named TitlesByFundsFY16. in my data class file i so declared it, since i duplicated TitlesByFundsFY15 i forgot to add string @data.cs . my code is doing good now thank you very much once again :)
