Application Error occurs when scrolling(mouse wheel) an empty grid

HI,
I'm getting an application error whenever I'm doing a mouse wheel scrolling on an empty grid.
Some details:

===================================

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index (mscorlib)
