Disable the editable for rows

[vivek gs]

HI,

I used to remove the editable for particular row.

i used this 

$("#pqgrid").pqGrid( "option", "editable", function(ui){

                    var rowIndx = ui.rowIndx;

                    if ( $(this).pqGrid("hasClass", {rowIndx: rowIndx, cls: 'inactive' } ) ) {

                        return false;

                    }

                    else {

                        return true;

                    }  

                });

In table > tr i having the class has inactive but it doesn't seem to be working
