We would like to use an igPivotGrid to enter data related to business targets.  We have a prepopulated cube with empty values and would like to be able to enter target values into the onscreen cells and write them out to a dataset (not the input datasource, though previously filled-in data in this output dataset will wind up in the datasource when it is subsequently read).  I was looking for some functionality analogous to the Updating functions in igGrid, but have been unable to find any.  In lieu of that, is there a CellUpdate event that I can tap into to get the needed info to write out my record?
