In your case grid as subgrid - the subgrid is simple grid - so the json format should be the same as those of the main grid.

subGrid: true,
subGridRowExpanded: function(subgrid_id, row_id)
{
  var subgrid_table_id;
  subgrid_table_id = subgrid_id+”_t”;
  jQuery(”#”+subgrid_id).html(”<table id='”+subgrid_table_id+”'

  class='scroll'></table>”);
  jQuery(”#”+subgrid_table_id).jqGrid(
  {
    url:”inv0003?id=”+row_id,
    datatype: “json”,
    //mtype: GET,
    colNames: ['Division<br />Number','Name','On Hand<br />Weight','% of<br />Total','Per Lb<br />Cost','Avg Monthly<br />Sales','Months<br />Supply','Turnover<br />Rate'],
    colModel:
    [
      {name:"divisionNumber",index:"divNum",width:80,key:true},
      {name:"divisionName",index:"divName",width:130},
      {name:"onHandWeight",index:"ohWeight",width:80,align:"right"},
   {name:"percentOfTotal",index:"pctOfTotal",width:80,align:"right"},          
 {name:"perLbCost",index:"perLbCost",width:100,align:"right",sortable:false},
 {name:"avgMonthlyWeight",index:"avgMonthlySales",width:80,align:"right",sortable:true},
 {name:"monthsSupply",index:"monthsSupply",width:80,align:"right",sortable:true},
 {name:"turnoverRate",index:"turnRate",width:80,align:"center",sortable:true},
      ],
      height: 100,
      rowNum:20,
      imgpath: “../javascript/JQGrid/themes/green/images”,
      sortname: 'divisionNumber',
      sortorder: “asc”
    });
  },

Why do not see the examples in the docs? They speak quite.

One possible solution (from demo site):

{"rows":[{"id":"1","cell":["1","item 1","2.00","100.00","200.00"]},{"id":"2","cell":["2","item 2","3
.00","50.00","150.00"]},{"id":"3","cell":["3","item 3","1.00","50.00","50.00"]},{"id":"4","cell":["4"
,"item 4","1.00","200.00","200.00"]}]}

{"rows":[{"divisionNumber":..........}]}

Do I need to specify more things than just "rows"?  Because although the JSON string is correct, the subgrid is not being populated.

Since you use the subGridRowExpanded as of documentation:

This event is raised when the subgrid is enabled and is executed when the user clicks on the plus icon of the grid. Can be used to put custom data in the subgrid.

• pID is the unique id of the div element where we can put contents when subgrid is enabled,
• id is the id of the row

If you have the id then you can $("#mygrid").getRowData( id ) - this retun all the values from the current clicked row and before constructing the grid you can pass what you want from this array

Regards

For instance, if the first column is "Customer Number," and I click the plus sign on the row that has a customer number of "0001," then, I would like for the program call to appear something like "svrpgm?custNum=0001".

I think there must be better explanation of your problem

 beforeSubmit: function() {
                 var sr = jQuery("#list").getGridParam('selrow');
                 var rowData = jQuery("#list").getRowData(sr);
           
                  this.editData = {"NU_RIF_EMPRESA" : rowData['NU_RIF_EMPRESA']};
                  retarr = {"NU_RIF_EMPRESA" : rowData['NU_RIF_EMPRESA']};
                  return retarr;
  }

Here I take the field NU:RIF_Empresa and add it to my QueryString data..
