If I correctly understand your question then you want to remove "+" (expand subgrid) icon for rows which have no elements in the subgrid. In the case you can follow the old trick described in the old answer. You can add loadComplete handle which removes some "+" icons from the grid having subGrid: true option. You need just know rowids of all rows of the grid which have no subgrid and do for the rows
$("#" + rowid + ">td.sgcollapsed").unbind("click").html("");
UPDATED: I posted the modification of free jqGrid which allows easy implement the requirement without the above hack.
The demo demonstrates the new feature. The implementation is very easy. It contains hasSubgrid callback inside of subGridOptions. The callback have options which is object with the properties rowid, data and two less important properties iRow and iCol. The code of the demo uses options.data which represent the data of the row. The demo creates subgrid only if input row have tax higher as 20.
subGridOptions: {
hasSubgrid: function (options) {
return parseFloat(options.data.tax) > 20;
}
}
You can use mySubgrids[options.data.rowid].length in your case, if I correctly understand the format of your input data.
