footer in subgrid


Can i attach the footer to a sub-grid? I want to do a sum on a column in the sub-grid.


Technically yes - sub-grid supports full set of API, so you can use attachFooter command from onSubGridCreated or onSubGridLoaded event, or define it in the same way as for normal grid in configuration XML.
There are few known issues with sizing subgrids with footers in current version , latest version of sub_row_grid extensions , where all known problems fixed, sent by email.
