Here are the solution of the error mostly come in such cases

Its Due to the Becoz you have added chart controls(or any thing)
and you forget to see that there is some thing wrong in toolbox on left side pane!
so just open it!

Actually you have two tabs with same name 'Data' just right click on the new tab(like tab which contain chart control) and rename it to any thing else like i have changed it to 'Chart Data'!
It will work fine!
ask me if you have any question!
