Question

Problem: jqGrid with subgirds. I want to disable the expand/collapse functionality for some rows of the main grid.

Answer 1

I actually found a way:

grid.jqGrid('setGridParam',{
                afterInsertRow: function(rowid, aData, rowelem) {

                    var rowData = grid.getRowData(rowid);
                    if(**Condition**){
                        $('tr#'+rowid, grid)
                         .children("td.sgcollapsed")
                         .html("")
                         .removeClass('ui-sgcollapsed sgcollapsed');
                    }
                }
            });

There was a bit of a problem. The code @Frank removed the icon, but the ‘click’ event was still triggered. Trying to unbind the ‘click’ event doesn’t seem to work, probably because it is attached later on ( maybe on gridComplete). Anyway, I figured that the click event is attached using one of the ‘ui-sgcollapsed sgcollapsed’ classes, so if you remove them, the event won’t be attached.

Hope it helps.
