I am testing the Formula Range Selection Demo in you Essential Studio WPF Grid version 2010 Vol 3.
I can use the VLOOKUP formula, e.g. =Vlookup(340,A1:b50,2,false).
And the cell will show the reference cells data.
But when I updated the reference cells, the VLookup cell does not updated until I go and double click in the cell.
