I searched here, but couldn't find solution to my problem.
I was trying to use the example code, Simple Subgrid worked fine. However, Subgrid 2 Level is not working.
displaygrid.php contains:
$grid->setSubGridGrid("displaysubgrid.php");
when I try to have the following code in displaysubgrid.php
$grid->querySubGrid(array(&$rowid));
I get output like
{"rows":[{"stockNumber":"LOT1","stock":"5","expiration":"2013-01-01"}]}
Which means data passing is okay. However, when I try to use the following
$subtable = $subtable."_t";
$pager = $subtable."_p";
$grid->renderGrid($subtable,$pager, true, null, array(&$rowid), true,true);
it's showing empty grid!
