sub_row_grid $ GridConnector

How do i link a subgrid to a connector php?

You need to use the onSubGridCreated event:

mygrid.attachEvent("onSubGridCreated",function(subgrid,rId,rInd,data){ subgrid.setHeader("Sales, Book Title, Author"); subgrid.setInitWidths("70,250,*") subgrid.init(); subgrid.setSkin("dhx_skyblue") subgrid.load(url,function(){ subgrid.callEvent("onGridReconstructed",[]); mygrid.setSizes(); },"json"); return false; // block default behavior })
