I tried custom buttons, but it's a little different from what you've suggested. I can now delete and add but still having problem with it. Let me explain the situation in detail...

I'm having a master grid that lists out all book lists. When I click on a book list, it will list out the users who subscribed that book list in another gridvew (detail gridview). I followed the example from the demo page, "Master Detail", http://www.trirand.com/blog/jq.....qgrid.html.

What I want to do is to be able to add / delete users from the detail gridview. Literally, I can add / delete users of a book list. The problem now is that when I delete a user of a book list and then I click on another book list and try to delete the user, it doesn't delete that user. I don't see any problem with add.

                
$("#del").click(function(){
     var gr = jQuery("#tags").jqGrid('getGridParam','selrow');
     if( gr != null ) {
        var val = jQuery('#tags').jqGrid('getCell',gr,'list_id');
        jQuery("#tags").jqGrid('delGridRow',gr, {reloadAfterSubmit:true,

        onclickSubmit: function(params){alert(val); return {list_id:val};}});
     }
     else { alert("Please select row to delete!");  }
});

I notice that the culprit was the  on the onclickSubmit event. If you see the code, I'm trying to get the list_id from the gridview ("val" variable), and it is fine. Inside the onclickSubmit event, I try to display the "val", but it always displays the previous list_id.

Is this a bug? Or, is this probably cache? If yes, how to clear it?

I did exactly the same thing for add, I could get the correct list_id everytime.

$("#add").click(function(){
   var gr = jQuery("#tags").jqGrid('getGridParam','selrow');
   if( gr != null ) {
      var val = jQuery('#tags').jqGrid('getCell',gr,'list_id');
      jQuery("#tags").jqGrid('editGridRow','new', {closeAfterAdd:true, reloadAfterSubmit:true,

      onclickSubmit: function(params){return {list_id:val};}});
   }
   else {
      alert("Please put cursor on the grid!");
   }

});

1. you can use the pre-submit events to store global variables holding the rowid and the cellvalue (your userid).

2. then have a custom button function that triggers an ajax post:

example….

.jqGrid('navButtonAdd','#jQGridpager',{buttonicon:'ui-icon-wrench',
    onClickButton:function(){$.post('my-delete-url?rowid=therow&user=userid');},caption:'Delete!'});

[edit: if your post already works then just read #1 and store the cellvalue in a variable]

                });
                
                jQuery("#tags").jqGrid('navGrid','#pagernav2',
                    {add:true,edit:false,del:true,search:false}, //options
                    {}, // edit options
                    {mtype:"POST",closeAfterAdd:true,reloadAfterSubmit:true,
                        onclickSubmit: function(rowid){
                                                            var val = $('#tags').getCell(rowid, 'list_id');
                                                            return {list_id:val};
                                                        }
                    }, // add options
                    {mtype:"POST",reloadAfterSubmit:true,
                        onclickSubmit: function(rowid){
                                                            var val = $('#tags').getCell(rowid, 'list_id');
                                                            return {list_id:val};
                                                        }
                    }, // del options
                    {} // search options
                );

This part always returns false: var val = $('#tags').getCell(rowid, 'list_id');

Any clue??

This is what I tried but didnt work.

onclickSubmit: function(rowid) {
var val = $('#tags').getCell(rowid, 'user_id');
return {user_id:val};
}

Please help....I can't delete or add anything.
