I have stable exception at use of function EnsureVisibleVertically() for scroll after addition new row to end of the grid.

Test project (VS2010) I has sent to you the day before yesterday, but has not received the answer.

Exception text: "Index was out of range. Must be non-negative and less than the size of the collection."
