I would appreciate an explanation as to why the data in the subgrid is not available immediately after the subgrid code executes.

I have a grid as a subgrid.  I am trying to read data from the subgrid in the function for the subGridRowExpanded event.  getRowData and getCell come back with undefined values.  This logic works fine if it is a click function external to the subgrid but not in the subGridRowExpanded event.

What am I missing here? Code below.

Thanks,

Jerry
