It may possible you are face off the problem to synchronize some other items in your GUI when you delete a row in your jqgrid.

You can use this tip to do it :

var myDelOptions = {
    onclickSubmit: function(options, rowid) {
          var grid_id = $.jgrid.jqID($( "#tip" )[0].id),
             grid_p = $( "#tip" )[0].p,
             newPage = grid_p.page;

          // reset the value of processing option which could be modified
          options.processing = true;

          // delete the row
          $( "#tip" ).delRowData(rowid);
          $.ajax({
                url: 'backend/ip.php',
                type: 'POST',
                data : 'oper=del&id=' + rowid,
                dataType: "text",
                success: function(data, status, xr) {
                         $( "#troute" ).trigger("reloadGrid");
                         $( "#tip" ).trigger("reloadGrid");
                },
                error: function(e) {
                         //called when there is an error
                         //console.log(e.message);
                }
           });
           
           $.jgrid.hideModal("#delmod"+grid_id,
                             {gb:"#gbox_"+grid_id,
                              jqm:options.jqModal,onClose:options.onClose});

           if (grid_p.lastpage > 1) {// on the multipage grid reload the grid
                    if (grid_p.reccount === 0 && newPage === grid_p.lastpage) {
                        // if after deliting there are no rows on the current page
                        // which is the last page of the grid
                        newPage--; // go to the previous page
                     }
                     // reload grid to make the row from the next page visable.
                     $( "#tip" ).trigger("reloadGrid", [{page:newPage}]);
            }

            return true;
     },
     processing:true
}; // fin variable

 $("#tip").jqGrid({
     url: "backend/ip.php",
     datatype: "xml",
     mtype: "GET",
     colNames: [" ", "Prefix", "Longueur", "Device"],
     colModel: [
                { name: 'myac', width:80, fixed:true, sortable:false, resize:false,
                  formatter:'actions', formatoptions:{editbutton: false, onedit:null,
                  delbutton:true, delOptions: myDelOptions}},
                { name: "prefix", width: 125, align: "center" },
                { name: "longueur", width: 100, align: "center" },
                { name: "device", width: 75, align: "center" }
      ],
      [...]
      caption: "Affectation IP / Intf"
});

[...]

The great thing is that you are able to make some data / gui treatment. Here I make a data update by means of a jquery ajax call and update jqgrids by means of two trigger(“reloadGrid”) calls.

Hope this can help

It is been a while I check forums and Ubiquiti products. They are really good products. At the beginning the really interesting thing in ubiquiti was the Open minded / Open Source direction they used. I begun to use their product with SR and XR card (when they don’t seek any final products). It was really easy to make your own product firmware with an embedded MIPS motherboard and their cards. The SDK was available at this time.

I check recently and now it is not. Ubiquiti has been introduce in Wall Street. I am really disappointed because when I was interviewed by them for their papers to be introduce to Wall Street I insisted on the fact of they success OpenSource is one main of it.

I would want to make some patch on kernel to be able to pass PPP/IP DSCP to their Atheros card to be able to do the same thing with IP (http://wiki.ubnt.com/AirMax_-_QoS_DSCP/TOS_Mappings). Now SDK is not available and I am really disappointed.
