Hi everyone, 

i have a kendo Grid with columns virtualization enabled. It works perfectly but comes a weird behaviour when I add aggregate columns.

The problem consists in the constant relocation of aggregates cells values when scrolling horizontally the grid, i.e aggregate cell keeps changing column : the more you scroll, the more it jumps from a column to another.

I provided this jsFiddle sample to help you reproducing the problem.

Keep scrolling horizontally and keep an eye on "Field6"  and "Field8" columns where aggregates have been configured and you will see that the corresponding aggregates values will constantly go on wrong columns.
